Naturally efficient

At its launch in September the 308 will become the first model to carry a number ending in 8. It will build on the strengths of its predecessor, of which more than three million have been sold in 6 years, thanks to its concept based on a semi-high architecture, design, interior space, interior light levels and a unanimously recognised high standard of road holding. As a vehicle of a new generation, it develops further the plus points and at the same time decelops new ones, mainly in favour of environmental efficiency and quality. With this aim in mind, particular attention has been paid to aerodynamics in order to improve the overall performance. As a result, the 308 has a low drag resistance (SCx 0.67 and Cx 0.29), resulting in a reduction in fuel consumption and CO2 emissions. The 308 will be available with a choice of six lean burn engines, including three petrol engines, developed as part of the partnership with the BMW Group, and three HDi diesel engines, one of which will have an emission level of 120 g CO2 per kilometre in the combined cycle. In addition to the engine range available, the designers of the 308 have also used different solutions to improve environmental efficiency. Consequently, the 308 will have a manual gearbox with an electronic control system, electro-hydraulic power assisted steering and new Michelin Energy Saver tyres, to achieve a significant reduction in fuel consumption and therefore in exhaust emissions. Finally, the European End-of-Life Vehicles Directive has been taken into account in the choice of materials allowing the recycling or re-use of 99% of the 308. The 308 project has benefited from the full attention and creative energy of the Peugeot engineers and designers, who have committed themselves to create a car whose quality is of the highest standard. Designed by the Peugeot Design Centre, the elegant, sporty lines of the 308 invoke dynamism and efficiency, whereas the forms and materials of the interior offer the occupants a prestigious style and finish. But the design - the first "force" of the emotion and feeling that triggers the ultimate act of buying - has exceeded its aesthetic function, by also emphasising the perceived quality of the vehicle. In designing the 308 it was not sufficient just to rely on the qualities of the interior, the high levels of interior light and the driving pleasure that contributed to the success of the 307, but instead evolve these in order to take them to a new level. This applies particularly to the interior, which takes full advantage of the available length of 4,276 m to establish what will be a reference in the segment. The interior light levels have been improved even more thanks to the fitment of a glass panoramic roof; which provides a total glazed area of 4.86 m2. With this configuration the five door hatchback offers overhead natural light to all the passengers on board. And finally, Peugeot's know-how with regard to suspension systems has resulted in choices that give the 308 a high level of driving pleasure and an excellent compromise between comfort and efficiency. In addition to its exemplary handling, the 308 is equipped with technology aimed at providing the highest levels of safety. This includes, the Lane Departure Warning System (LDWS) for the benefit of primary safety, the airbags, which can number up to nine, for secondary safety, and finally, the Peugeot Emergency Service (emergency call) linked to the RT4 telematics system, for tertiary safety. With the 308, Peugeot is offering a vehicle that will meet the expectations of customers of the compact hatchback market, which is the largest market because of the volumes it generates in Western Europe in particular. In fact, with nearly five million vehicle registrations in 2006, it represents approximately one third of the all­brands market and has increased slightly since 2001, the year when the 307 was first introduced. This market is made up of a diverse clientele. Although essentially made up of families, this clientele has a varied profile; both in terms of age and car experience, but they all want a prestigious vehicle that does not compromise on performance. The 308 will be launched within a particularly short time frame, the day after the Frankfurt Motor Show, where it will have its world premiere. The 308 will be available in the main European countries between the 20th September - the date of the commercial launch in France - and the 27th September. It is fitting that this new hatchback should share the semi-tall architecture which first appeared on the 307. It enables, in addition to the recognised qualities of all of the Marque's models (dynamic styling, class leading handling, etc), an optimised specification for this type of body shape. It provides interior space, visibility, brightness and compact packaging and the qualitative points of reference which have already won more than three million buyers for the 307 worldwide. The 308 therefore builds on the 307's technical platform, but develops it further in order to meet the project's high objectives: an assertive style, comprehensive specification and a high level of quality. During its design, the engineers and stylists have paid particular attention to the perceived quality and "quality feel". With the 308, Peugeot has blended in all the ingredients to appeal to a highly diversified customer base in search of self expression, modernity, attention to detail, control and convenience.

An exterior style more feline than ever

The 308 embodies in its own way the characteristic Peugeot genes that give all of the Marque's models their strong identity. Strengthening the obvious feline look is two esigns of "front" both with a different finish depending on the model: one is a "classic" style (for the entry level model); the other is more dynamic or "sporty". The strongly contoured lines of the "nose" of the car serve as the focal point and create a dynamic and flowing "V" profile which follows back from the bonnet into the front windscreen pillars. The profile of the 308 creates a dynamic impression of movement, thanks to the elaborately styled panels and flowing design of the windows. The lines at the rear of the vehicle help to identify it. The large wrap around lower bumper - which on top-of-the-range models combines with a rear diffuser - and large rear lights emphasises the wider rear profile and the large curved rear tailgate glass.

A new and original interior

The style of the interior is perfectly in keeping with the exterior architecture, with the adoption of a steeply inclined fascia panel to accentuate the feeling of space. Its fluid and elegant design coupled with the use of high quality materials (both to look at and to touch) creates an impression of quality seldom encountered in models in this market segment. The use of large expanses of glass combined with a panoramic glass roof (as standard or as an option depending on version) creates a bright interior conducive to user-friendliness and the wellbeing of occupants. Rear passengers will be particularly at ease in the 308 thanks to its generous interior space resulting from its architecture and the design of the front seats. The attention to detail enjoyed by the occupants of the 308 is part of an approach designed to ensure their utmost wellbeing, thanks in particular to important work carried out on the control of the interior temperature and noise insulation, and also the availability of numerous and ingenious storage spaces.

Dynamic efficiency: exceptional road holding

The chassis and suspension of the 308, assisted by the excellent body rigidity, have been meticulously developed to obtain the best possible combination of road holding and comfort, making the 308 a benchmark in its category. The electro-hydraulic power steering offers the driver maximum precision, assured by pseudo McPherson type front struts and a rear torsion beam. In addition, a wider front and rear track and larger tyres (up to 18'') enhances the overall efficiency of the vehicle.

Environmental efficiency

The search to lessen the environmental impact of the vehicle was a key objective in all stages of development of the 308. Whether it was with regards to recycling, aerodynamics, its petrol and diesel engines based on recent or original technology, the additive-based diesel particle filter system on the HDi diesel versions, its wheels and suspension (including Michelin Energy Saver tyres and electro-hydraulic power steering), reducing weight (involving the use of composite materials, aluminium and high-strength steel), everything has been carefully studied to optimise fuel consumption and reduce CO2 emissions. Indeed, the CO2 emissions of the 1.6 litre HDi 66kW (90bhp) 308 has been reduced to just 120 g in the combined cycle. A wide range of modern, high-performance engines that are economical and environmentally-friendly The 308 offers a wide choice of power trains; there are 10 in all, to meet the requirements of the broadest possible customer base: three petrol engines, three HDi diesel engines and five gearboxes. Petrol versions of the 308 feature the most recent engines developed jointly by the PSA Peugeot Citroën group and the BMW Group: The 308 HDi offer consists of engines all featuring HDi direct injection technology: (*) engines and gearbox options available at the time of launch; others wil follow shortly after the launch.

Maximum efficiency in terms of safety

The objective to provide exemplary road holding forms the basis of the primary safety of the 308. This is supplemented by a range of equipment such as a Lane Departure Warning System (LDWS) and bi-Xenon directional headlamps. At the level of secondary safety, the structure (particularly through the use of 3 impact absorption structures at the front) and bodywork that has been designed in terms of its rigidity and ability to deform in a controlled manner, provides optimal impact protection. In addition, the 308 can be equipped with up to 9 airbags, including 2 rear side air bags and a steering column air bag. According to countries, the "Peugeot Emergency" service, linked to the RT4 telematics system, ensures tertiary safety by pinpointing the vehicle's location and organising the dispatch of appropriate assistance.

Colours, trims and structure of the range

With 12 exterior body colours, 5 trim levels, different choices of interior ambience, cloth or leather trim, and even an integral leather fascia panel, the 308 knows how to play the "exclusive" card to appeal to customers.

The market

Maintaining a range strategy, consisting of a number of different models able to meet if not exceed the requirements of a varied customer base, has always been a key objective for Peugeot. In 1934, the Peugeot range consisted of four individual models: The top-of-the-range 601, the 401 (upper medium segment), the 201 in the most popular segment and of course, even then, a 301 between the latter two models, most of the models were also available in different body styles (saloon, two door versions, open-top coupé, etc). With the introduction of the 3 series, Peugeot entered the compact vehicle market segment, which has grown steadily over recent decades. Young professionals looking for a dynamic, expressive and modern vehicle, older people in search of versatility, couples without children, young families: whether coming from the next range down or the next range up, customers in this segment (M1) are today particularly diversified. This segment offers many different choices and numerous benefits, be it in terms of value for money, vehicle size and interior space. Indeed the latter is of particular importance in explaining the success of the 307.

The 307

Launched in 2001, the 307 stood out completely from other hatchbacks in its segment thanks to its semi-tall architecture. Taking on board the possible demands of future customers, Peugeot took the innovative risk of proposing a single volume vehicle with a very forward-positioned front windscreen and unusually tall architecture for the time. The result was a vehicle which offered generous interior space, excellent visibility and interior brightness for its occupants. Benefiting also from a resolutely elegant style, impeccably dynamic road holding and particularly innovative equipment for its segment, the 307, thanks to its excellent versatility, it has already sold more than 3 million during the six years since its launch, a record figure for the Marque in the compact vehicle segment. The 307 has left its mark; its concept, now an essential part of the motoring landscape, was naturally the basis for the conception of the 308.

Conception

From the outset, the aim of the project was to ensure the 308 featured all of the strong points upon which the success of the 307 was built, but also develop them even further. The experiences gained with the 307 and its architecture and the technological advances made by the Marque, have made it possible to pull off this challenge and, at the end of the day, meet very high quality targets. As a result, the project named “T7� was built around the 307 platform and its architecture. It was on this basis that all design studies were carried out and that teams in the Styling, Engineering and Marketing departments worked together to create the 308.

Exceptional style, road holding and aerodynamics

The platform

The “T7� project is based on platform 2 of the PSA Peugeot Citroën group. This ensures straight away that the 308 had a solid foundation for its development. This platform, modified and optimised, stands out due to its excellent rigidity, ensuring optimal performance of the mechanical assemblies and suspension but also providing good noise and vibration suppression.

Exterior dimensions

Through its exterior dimensions, the 308 offers an excellent compromise between interior space and overall dimensions. A length of 4.276 m, or only 74 mm more than the 307 despite a very high level of safety and repairability, with: A generous width of 1.815 m, an increase of 85 mm compared to the 307, ensuring excellent lateral passive safety and interior passenger compartment width. A height, which continues to set the car apart in the compact saloon segment and makes possible its generous interior space - 1.498 m (12 mm less than the 307 as a result of the optimised styling and aerodynamics). Similarly, to meet the requirements of the styling and road holding, the front and rear tracks have been widened compared to those of the 307 (e.g. with 15’’ wheels): Larger wheels, clad with 195/65R15, 205/55R16, 215/55R16, 225/45R17 and even 225/40R18 tyres (available on numerous versions), also enhances the general style of the 308 and its road holding efficiency.

Aerodynamics

The styling and dimensions of this new Peugeot allow for a particularly efficient aerodynamic specification. Indeed in this respect, the 308 is clearly one step ahead of its predecessor; its exceptional Cx of 0.29 is better than that of competitor’s five door models. This excellent result and the SCx that results (0.67), despite a cross sectional area (S) of 2.3 m2 due to the height and width of the car, is the result of extensive work carried out in the wind tunnel on the vehicle’s body. The final result is a reduction in fuel consumption combined with low running costs and optimal environmental efficiency.

Exterior style: more feline than ever

On the basis of the 308 specification which determined its semi-tall architecture, stylists worked at a very early stage on giving the future model a true Peugeot identity. From 2003, mock-ups were built and used to illustrate general ideas. >From the end of that year, in the design studio then still based at the La Garenne Centre, project T7 ran alongside that of the 907, the fabulous concept car revealed at the 2005 Paris Motor Show. It was in this creative atmosphere that the idea of a particularly sculpted and expressive design at the front was born, with the Lion badge resting on what could truly be called the “nose� of the bonnet. Looking at the Marque “lion� badge at the front, the flowing styling lines rise up over the bonnet and into the front windscreen pillars. The prescribed “V� outline gives the entire car its shape and creates an impression of motion even when the vehicle is at a standstill. This impression is further enhanced when the car is equipped with a panoramic glass roof, ensuring a perfect visual continuity with the large front windscreen. The particularly feline looking front headlights extend harmoniously along the bonnet profile. Four “circular lights� with an attractive technical finish give the vehicle a “look� that is both bright and eye catching, and are clearly visible through the clear headlamp lenses. The design of the front with its visible feline characteristics is accentuated still further by a single two part air intake grille. According to the version, the front grille has either two chrome mouldings or is in an aluminium finish; both (particularly the latter) emphasise the car’s dynamic and distinguished character, while integration of the front bumper strengthens the impression of overall solidity. The shape of the fog lamps is reminiscent of those of the 907. Positioned at each end of the lower front bumper panel, they make the vehicle visually appear much wider and give the impression that the 308 is “glued to the road�. The design of front of the vehicle sums up in essence all the Peugeot traits, while further accentuating the feline appearance. This strong identity, immediately recognisable and evolving with each new model and generation, means that the Marque always stands out, capitalising on and strengthening its image and brand awareness, particularly in new markets. The Peugeot stylists also sought to give as dynamic a feel as possible to the profile of the 308. Accordingly, a visual “waist line� runs the length of the body, plunging from the rear lights to the front wheel arches. This line also follows the curved shape of the rear lights, marking out the function of the direction indicator before tapering towards the lower rear panel and disappearing, before reaching the wheel arch. In parallel, the glazed areas and the tapering waist line and particularly the front corner window, create a visual extension to the body, enhances the fluidity of the shape. This becomes even more pronounced on the three door 308, thanks to the steeply inclined design of its rear quarter panel window. Similarly the wide curved rear tailgate glass, by “encroaching� upon the rear quarter panel pillars, gives a very original and innovative feel to the profile of the body. The shape of the doors, and also the side mouldings, are designed to capture the light in an optimal way and give a real sensation of robustness and quality. The design of the rear doors emphasises the bold contours of the rear wings of vehicle. Lastly, the particularly expressive finish of the lower section and the sill panels helps to establish the overall design. At the rear, horizontal lines visually “extend� the vehicle; this styling effect is intentional, creating the impression that the 308 is in its natural element on the road, if not at one with it. The large lower rear bumper panel further enhances this feeling, particularly in the top of the range version, which includes a stylish diffuser trim panel – in the manner of the 407 Coupé – in which two chrome inserts appear to give the impression of exhaust nozzles. The rear lights exhibit a rich, hi-tech appearance with visual detailing forming diagonal strips. These bear resemblance to the lights of the 307CC, particularly when they are on, and also those of the 504 coupé cabriolet of 1969. To sum up, each detail, each visible component of the vehicle has been carefully studied and designed in a mutual exchange of ideas between stylists and engineers. This relationship made it possible to break new ground in terms of perceived quality, with a precise study made of how best to treat each surface, each convergence, each element of the vehicle.

Interior style: dynamic, stylish contours and materials

To determine the interior style of the 308, the intention firstly was to highlight and exploit as far as possible the space made available by the semi-tall architecture. One objective was to give the interior a very prestigious feel, both in terms of the design and the materials used, by offering an unmistakeable perception of quality. From the end of 2002, i.e. well before the launch of the “T7� project and even before the first exterior designs, the general idea for the fascia panel took shape among Peugeot’s designers, who were working on innovative “advanced� projects. There was a wish from the outset to make the fascia panel pure, elegant and dynamic, offering a particularly clear view of the exterior thanks to its steeply inclined profile, almost symmetrical with the front windscreen pillars. After exploring other alternatives at the launch of the T7 programme, the decision was finally made to adopt this theme. Engineers were therefore able to reflect, find and implement all of the technical solutions needed to create this interior architecture, without detracting in any way from the vehicle’s performance levels in terms of ergonomics, practicality (storage volume) or temperature regulation (thanks to the design of a compact, high-performance air conditioning unit). The quality of the finish and a concern for the wellbeing of the occupants inside the car then became a true obsession among the stylists: Bold shapes, the appearance and softness to the touch of each element, the overriding sense of space and interior brightness: everything inside the car captures the senses and encourages the desire to spend time inside... The interior is available in three ambiences, creating a luxurious and welcoming feeling, flattering the senses of all the occupants.

Enjoyment and wellbeing …

The semi-tall architecture of the 308, offering interior freedom, space and brightness, provides occupants with a high level of comfort and perceived quality.

Come in and take a look …

With a total glazed surface area of 3.60 m2 in the five door version, unrivalled in its segment, the 308 offers its occupants a much appreciated interior brightness. The interior brightness can be increased even further with the fitment of a panoramic glass roof, which also removes a visual barrier between the rear passengers and the exterior. With the fitment of the panoramic glass roof the total glazed surface area increases to 4.86 m2. The spectacular brightness diffused through the panoramic glass roof can be increased or reduced by means of an electric sunblind with two sliding sections and a safety auto-reverse function. On some versions, sun blinds built into the top of the rear door interior trim panels can be pulled up covering the window and shading the passengers.

Organisation of the passenger compartment for optimal space and comfort …

For occupants … The semi-tall architecture of the 308 means that organisation of the passenger compartment can be dedicated solely to the wellbeing of passengers through the use of bespoke features. The elegant and uncluttered circular-shaped fascia panel, soft to the touch, provides everything necessary for driving and comfort and is anything but invasive. The ergonomically designed and stylish door panels are very welcoming and offer good elbow support. The front seats with their contemporary styling express comfort and support without monopolising the interior space. Their special design of the frame frees up space for the legs and feet of the rear passengers. The raised position of the rear seats combined with the compactness of the front seats creates an “amphitheatre� effect which favours forward visibility and also improves leg room. At ease in a bright and roomy car, passengers can enjoy the available interior space with dimensions that speak for themselves:

.. and for luggage …

The rectangular shape and clever layout of the boot allows for easy and practical use of the available space 430 litres (or 348 dm3 VDA) under the rear parcel shelf, or 442 litres (368 dm3 VDA) above the seat backs, including: A “ski flap� allows the transportation of long objects which can extend into the passenger compartment, while the design of the rear seats – which divides 40/60 (seat back and seat cushions) – makes it possible to increase the boot volume to 1 398 litres (1 201 dm3 VDA). Adjustable straps and a luggage net (according to versions) complete the practical aspects of the boot. The luggage net can be installed in different ways by means of twelve fixing hooks from which shopping bags can also be suspended. The boot carpet can be raised using a strap and held in a raised position to enable hands-free use, by means of a red hook located on the rear parcel shelf.

Numerous storage spaces …

Testifying to the attention paid to the comfort and convenience of the car’s occupants, storage spaces are numerous and cleverly appointed, offering a total storage volume of nearly 42 litres. They include: According to versions, other storage areas are proposed:

An ingenious rear parcel shelf

On some versions the traditional rear parcel shelf is replaced by a parcel shelf with a storage area of 8.75 litres, with a lid, able to hold objects, an umbrella or a tennis racket. Its clever lid has two opposing handles, making the contents of the storage area accessible from inside the car or from the rear with the tailgate open. Like the traditional parcel shelf, it can be stored upright behind the rear seats or flat at the bottom of the boot.

Welcoming seats …

Symbolic of comfort and an important factor to user-friendliness, the seats of the 308 have been lavished with creativity and attention. Rear passengers will thank the stylists for having designed front seat backs with them in mind… Their compact dimensions save space and enhance forward visibility. Designed around a new frame - compact to maximise space and rigid to resist the severest impact thereby providing optimal protection to the occupants – the seats of the 308 are welcoming and offer comfort and support. Their different original and distinctive finishes, according to level, are manufactured from in situ foam which facilitates the successful moulding of complex shapes. Complete with leather trim, they offer more pronounced support. Heated seat cushions are also available as an option. Installed slightly lower than those of the 307 (- 15 mm) to offer a driving position more in keeping with a saloon than an MPV, they nonetheless offer a height adjustment of 50 mm (+ 13 mm and - 37 mm) with respect to nominal height by means of an active seat height adjustment allowing a multitude of driving heights. They slide over a distance of 230 mm to ensure driving comfort for all sizes of seat occupants. In another innovation, the front seats can benefit from lumbar adjustment, and the driver’s seat (on leather versions) can be equipped with a 4-way electrical seat adjustment with memorisation of seat positions. The rear seats divide 40/60 and feature a ski flap on many versions. Thanks to their practical operation they can be tilted and folded, and the seat cushions can be removed very easily to benefit from maximum length as required.

No effort spared…

To enhance the comfort of 308 users numerous features have been developed and are available on certain versions. To see better

To breathe more easily …

The ventilation system of the 308 has been carefully designed to enhance in-car comfort thanks to an exceptional air distribution system supplied by five air vents on the fascia panel, heating rails under the fascia panel directed at the feet, and two air vents with adjustable flaps for the rear passengers. In addition, the 308 benefits from a new and even more powerful air conditioning unit available in two levels: manual air conditioning and automatic dual-zone air conditioning; the latter can also operate in single-zone mode, with a single control, when only the driver is present. A filter protects the passenger compartment from dust and pollen. With dual-zone air conditioning, an active charcoal filter also eliminates certain hydrocarbon odours. On some versions, an athermic front windscreen, rear side sun blinds and the electric sun blind on versions with a panoramic glass roof further enhance the comfort of the occupants.

Select a fragranced atmosphere …

A further testimony to the attention paid to the occupants of the 308, a fragrance diffuser dispenses into the passenger compartment, with the required intensity, a fragrance from among a range of six proposed: Spring flower, Exotic vanilla, Cocoon lodge, Wood sensation, Sweet air and Pure sensation (with anti-smoking properties). These fragrances have been selected with due regard for the health of occupants and the environment. The re-sealable cartridge is located in the middle of the central air vent.

Acoustic comfort …

An essential feature of in-car comfort, noise insulation has been taken into account at all levels of the design and entailed: A sign of attention to acoustic comfort rarely encountered at this level in the range, the 308 offers optional “laminated side windows�.

A very high level of primary, secondary and tertiary safety

For all of the Marque’s new vehicles, safety is a crucial factor in any project. It is therefore factored in at the earliest design stage. The 308 benefits from the Group’s wide experience in this respect and from the latest technological advances to ensure safety of the highest order at all levels. Primary safety: the excellent rigidity of the structure, wheels and suspension (a historic strong point of Peugeot) and electronic assistance systems, will ensure that the 308 becomes the benchmark vehicle for road holding in its segment. Secondary safety: the body structure is very generously dimensioned to withstand even the severest impact, such as those used in EuroNCAP tests. The designed controlled deformation of the structure and its individual protective devices (air bags, seat belts, seats) will ensure that the 308 meets the requirements to achieve five stars in the adult occupant protection test. In respect of tertiary safety, the Marque continues to pave the way thanks to the Peugeot Emergency service which is included with the RT4 telematics system available on the 308. This system, launched in 2003, has proven its effectiveness by saving many lives. Today it is accessible in many European countries.

An optimised structure

The 308 is designed structurally to dissipate impact energy in a designed and controlled way. It follows the fundamental design principles of the 307 while incorporating a number of improvements, such as three impact absorption structures, to satisfy the more stringent safety objectives and allow for compatibility with this new specification, such as the fitment of a panoramic glass roof. The aim is thus to protect the passenger compartment in optimal fashion (and its occupants), to limit the consequences in the event of collision with a pedestrian, and to facilitate repairability; which obviously has a direct affect on insurance costs for the car’s user.

Front impact

While the principle of the rigid steel one-piece structure of the 307 is adhered to in general terms, the engine compartment, however, has been entirely redesigned, with: In the event of a front impact, three fifths of the impact energy is absorbed via the main impact structure, 1/5th via the lower impact structure and 1/5th via the third impact structure. The use of these “three� impact force absorption structures enables all the forces to be concentrated and theassociated forces directed along pre-determined “channels� into specially strengthened areas: the bulkhead, the sub frame and the sides of the body. This enables the creation of an occupant protection cell around the passenger compartment. In addition, the steering column of the 308 is fully collapsible: in the event of an impact, it can retract to a predetermined position to protect the driver. An “active� footrest maintains the angle of the driver’s foot, thereby reducing the risk of injury to the ankle. Lastly, the ongoing objective of raising the level of safety whilst limiting its impact on vehicle weight led to the widespread use of lighter materials than ordinary steel. For example, the use of high-strength steels accounts for 11 % of the weight of the metal structure (compared to 6 % on the 307). With this in mind, the bonnet, lower impact absorption structure and door reinforcements are all manufactured from aluminium, while the wings and many other body components are manufactured from composite materials.

Side impact

To offer occupants optimal protection in the event of side impact, the ‘B’ post has been strengthened on the 308 through the use a “multi­layer� technique. Indeed the ‘B/C’ posts are made from three different thicknesses of metal, two of which are high-strength steel. The B post is also strengthened at its base, evident by its shape where it meets the lower sill panel and clearly visible with the front doors open. All the doors help effectively to ensure the car’s structural rigidity by creating a solid barrier between the ‘A’ and ‘B/C’ posts and the rear wheel arch. They are fitted with aluminium side impact reinforcements and door sill stiffeners. Impact absorption padding is also fitted inside the doors. Similarly, the side panels of the body structure are reinforced and cross members have been added between the outer body sill panels helping to ensure the vehicle’s rigidity.

Rear impact

At the level of the boot sill, an aluminium alloy impact bar has been incorporated to absorb rear impacts, reducing the effect on the body and thus ensure a good level of repairability. The rear style takes this structural element into account in the design of the tailgate, its rear lights and the large lower rear bumper panel.

Efficient means of restraint

To supplement the performance of the structure in terms of impact resistance, a range of protective devices has been developed to restrain and protect the occupants: Particular attention has been paid to child safety: indeed the 308 is fitted with three Isofix mountings to accommodate a child seat – one at the front and two in the rear side seats. The 308 can also be equipped with an electrically operated child safety device which simply and safely locks the rear doors and disables the electric rear windows.

Tertiary safety: a valuable time saver

The RT4 telematics system, available as an option, offers in addition to its audio, telephone and navigation functions access to an assistance service and to the Peugeot Emergency service. This emergency call service pinpoints the car’s location and is available free of charge for an unlimited duration. To date it is proposed in France, Germany, Spain, Italy, Belgium and Luxembourg. It puts the occupants in contact with a professional who speaks the customer’s own language. This service can be initiated manually or automatically (if a pyrotechnic device is triggered), ensuring rapid intervention by the emergency services. Since its launch in 2003, Peugeot Emergency has come to the assistance of more than 1,200 users. This emergency call system meets the requirements of the French civil defence organisation; it is approved by the Civil Defence and Security Department (DDSC), an annex of the French Interior Ministry.

A range of modern, efficient and environmentally-friendly engines

Shortly after the launch the 308 will be available with a wide choice of ten different power trains which will meet the different requirements of the largest possible number of customers in the segment. For the petrol versions, the 308 will be equipped with all new engines designed and developed in partnership between the PSA Peugeot Citroën and the BMW Group: the 1.4 litre and 1.6 litre VTi engines and also the 1.6 litre THP in its 110 kW (5 150 bhp) version. All benefit from particularly innovative technology, if not wholly original at this level of engine capacity. For the HDi diesel versions, the 308 is powered by the recent 1.6 litre 66 and 80 kW (5 90 and 110 bhp) engines and the 2.0 HDi developing a power of 100 kW (5136bhp), acknowledged for their driveability, performance and low running costs. An additive based diesel particle filter system comes as standard with the 80 and 100 kW engines. All of these four cylinder engines benefit from the most advanced technologies in their category. They all feature a cylinder head with 2 overhead camshafts and 16 valves.

1.6 litre THP: 110 kW (5 150 bhp) – EP6DT (*) The 1.6 litre THP (“Turbo High Pressure�), with a capacity of 1598 cm3, available in the 308 offers great operating flexibility thanks to its maximum torque of 240 Nm available from only 1400 rpm and ensures a remarkable driveability at low engine speeds. It produces a maximum power of 110 kW at 5800 rpm (103 kW at 6000 rpm in the automatic gearbox version). Its innovative Twin-Scroll turbocharger combines exhaust gases in an optimal fashion to ensure maximum pressure with minimal lag, while its high-pressure direct petrol injection system improves combustion and the engine’s overall efficiency. On the 308, this system creates a remarkable synthesisofperformanceandfuel consumption. For example, it takes the car only 8.8 s to go from 0 to 100 kph, with driver only, and in gear acceleration is exceptional: 7.8 s in 4th gear from 80 to 120 kph, with a petrol consumption of 7.1 litres/100 km in the combined cycle. 1.6 litre VTi: 88 kW (5 120 bhp) – EP6 (*) The 1.6 litre VTi (Variable Valve Lift and Timing injection) is an indirect injection naturally aspirated engine developing a maximum power of 88 kW (5 120 bhp) at 6000 rpm and a maximum torque of 160 Nm at 4250 rpm. This torque is available very uniformly, since even at low engine speeds (2,000 rpm), it attains 140 Nm, or 88 % of its maximum capacity, thereby ensuring a wide operating range. 1.4 litre VTi: 70 kW (5 95 bhp) – EP3 The newest arrival in the recent family of “EP� engines, this 1398 cm3 engine develops a power of 70 kW at 6000 rpm and a torque of 136 Nm at 4000 rpm. It also produces 86 % of its maximum torque, i.e. 117 Nm, at only 2000 rpm. Apart from the smaller capacity resulting from a shorter stroke, this engine features all of the technology found on the 1.6 VTi engine, such as the dual VVT system and the variable inlet valve lift system. This is no mean technological feat on a small 1.4 litre engine; the latter enables the basic level 308 to offer an excellent compromise between drive ability and fuel consumption.

HDi Diesel engines

2.0 litre HDi DPFS: 100 kW (5 136 bhp) – DW10BTED4 (*) With a capacity of 1997 cm3, the “DW10B� develops a maximum power of 100 kW at 4000 rpm and a generous maximum torque of 320 Nm at 2000 rpm. This torque can even attain 340 Nm thanks to the “overboost� function activated during hard acceleration, making for example overtaking much safer. To obtain this outstanding performance, the engine is equipped with a variable geometry turbocharger, an electronically controlled high­pressure pump (allowing a maximum pressure of 1650 bar in the common rail according to required load) and piezoelectric injectors with six apertures which send a fine spray of fuel into the combustion chamber (resulting in optimal injection both in terms of quantity and duration). This engine gives the 308 a dynamism that accentuates its road holding. With driver only, it accelerates from 0 to 100 kph in 10.1 s and in 5th gear from 80 to 120 kph in 8.4 s, while limiting fuel consumption to 5.5 litres / 100 km in the combined cycle. remarkable responsiveness and flexibility, with a maximum torque of 240 Nm from 1750 rpm. These characteristics are attained thanks to technologies such as its variable geometry turbocharger and its high-pressure direct injection system (up to 1600 bar). This maximum torque can be increased momentarily to 260 Nm thanks to the “overboost� function. This engine, which will form the “base of the diesel range� of the 308, thus offering an excellent compromise between performance and running costs (4.7 litres to travel 100 km in the combined cycle, or 0.2 litres less than a 307 with an equivalent engine). 1.6 litre HDi: 66 kW (5 90 bhp) – DV6ATED4 This 1.6 litre HDi engine develops a maximum power of 66 kW at 4000 rpm, for a maximum torque of 215 Nm from an engine speed of only 1750 rpm. Derived from the 1.6 litre 110 bhp engine, it is equipped with a fixed geometry turbocharger and uses the same direct injection technology. This basic level diesel engine will offer its owner excellent driveability on a day-to-day basis plus the benefit of particularly low fuel consumption for this segment, with 4.5 litres / 100 km in the combined cycle, or only 120 g of CO2 per km (approval pending).

Manual gearbox (*)

Five of the six engines in the 308 range are coupled with a 5-speed “BE� manual gearbox, adapted to the special features of each engine. The 2.0 HDi DPFS for its part comes with an “ML6C� 6-speed gearbox.

“Porsche Tiptronic system� automatic gearbox with sequential control

Two types of “Porsche Tiptronic� sequential control are available on the automatic gearboxes fitted to the 308. These gearboxes will appeal to customers particularly keen on convenience and ease of use, while still offering a more active driving style in sequential mode. An “AL4� 4-speed automatic gearbox is fitted on the 1.6 litre VTi 88 kW and 1.6 THP 110 kW petrol engines. The characteristics of this gearbox have been calibrated to optimise fuel consumption and offer the best possible compromise between fuel consumption and performance. On the 2.0 litre HDi DPFS, the “AM6� gearbox, which appeared on the V6 petrol and HDi engines of the 607 and 407, tops the diesel offering in the 308. Dynamic, responsive and able to adapt to the user’s driving style, this 6-speed transmission fully exploits the characteristics of this engine. In automatic mode, the controlled manual gearbox offers fuel savings compared to a traditional manual gearbox as a result of its electronic management and optimised gear change times.

6-speed electronically controlled manual gearbox (BMP6)**

The “MCP� piloted manual gearbox constitutes an all new offer within the Peugeot range. Coupled with the 1.6 litre HDi DPFS engine developing 80 kW (5 110 bhp), this 6-speed controlled manual gearbox, eliminates the need for a clutch pedal, it is a genuine alternative to a traditional gearboxes thanks in particular to its limited additional cost compared to the familiar manual gearbox. This new unit will appeal to drivers who like to change gear which can either be completed via the gear lever or paddles behind the steering wheel. Its inbuilt intelligence will meet the expectations of those who prefer stress-free driving by changing gear unaided, although the driver is able to “take over� at any time. (*) Note that engines and transmissions marked with an asterisk are those that wil be immediately available at launch, with other units being marketed shortly after (their characteristics, currently pending approval, will be communicated at a later date).

Peugeot expertise

Suspension

Road holding, directly affects the overall driving pleasure and is a recognised strength of Peugeot, but it also benefits active safety, and is central to the design of all vehicles in the Peugeot range. In this field, where the 308 aims to be a reference, particular attention has been paid to all factors associated with it. Structurally, the 308 benefits from an excellent torsional rigidity of 0.73 mrad for a torque of 100 daNm (a 10% improvement compared to the 307) allowing optimal use of its suspension. Based on the same platform as its predecessor, the 308 logically benefits from the same suspension layout that contributed to the recognised qualities of the 307. The front suspension is an inverted pseudo McPherson strut design with a linked anti-roll bar, in which the technology allows rigorous control and a good level of vibration filtration. The rear suspension, composed of a rear torsion beam, two suspension arms and an integral anti-roll bar, is compact in size and highly rigid, guaranteeing good vibration control and structural strength. Designed and produced by Peugeot for accurate fine-tuning, the 308’s hydraulic multi valve shock absorbers are pressurised to 3 bar to ensure a good compromise between comfort and road holding. On the 308, the mountings between the body and the sub-frame have been redesigned to improve the transverse rigidity of the front axle. Wider front and rear tracks, and also the generous width of the tyres and wheel (1/2 inch more than the 307), have a direct positive effect on body rigidity and the car’s precision and stability, both on straight roads and when decelerating and braking in curves. Similarly, the modified camber angle of the front suspension of -0.3, favours accuracy and control. The centre of gravity of the 308, lowered by 5 mm compared to the 307, also contributes to the car’s handling.

Steering

Accurate and ensuring good feedback, the rack and pinion steering of the 307 is renewed on the 308. Its variable assistance is controlled by a hydraulic electro-pump unit (GEP) in which the assistance varies according to vehicle speed, the speed of rotation of the steering wheel and the temperature of the power steering fluid. This allows continuous changes to the assistance levels as required. One new feature at this level: two types of GEP are available in the 308 range. This allows optimal parameter setting according to the engine and therefore the car’s weight and ensures enhanced directional control and road holding during manoeuvres. The 2.0 litre HDi DPFS 308 thus has a GEP with an output of 650 Watts, while that of other engines offers an output of 575 Watts.

Wheels: Michelin Energy Saver tyres

During development of the T7 project, Peugeot included Michelin in its programme of innovations. The aim was to significantly reduce the tyre’s rolling resistance, without any effect on its performance levels in terms of traction and safety, and ensuring a mileage among the best on the market. This work led to the development of a hi-tech tyre for the 308 belonging to the all new Michelin Energy Saver range. This tyre, while optimising rolling resistance by 20 %, reduces the amount of energy needed for vehicle traction, thereby obtaining a reduction of fuel consumption compared to the market average for a traditional tyre. The technology used for the first time in the world in the Michelin Energy Saver tyre featured on the Peugeot 308 contributes to the vehicle’s environmental efficiency. This technology allows a saving of almost 0.2 litres of fuel per 100 km in the combined cycle, or a reduction of 4 g of C02 per km*. This corresponds to around one tonne of C02 less emitted during the life of a vehicle. *ISO test carried out by the TÜV SÜD Automotive in 2005 on the 195/65R15 tyre. It will be available in 15 and 16’’ versions, on the 1.6 litre HDi 66 and 80 kW (5 90 and 110 bhp) 308 models.

Braking

At the front, braking is assured by large ventilated discs with a diameter of 283 mm and a thickness of 26 mm. Disc dimensions are 302 x 26 mm on the 2.0 litre HDi DPFS 308. The front brake calipers have an increased piston diameter of 57 mm to provide a good level of “feel�, performance and durability. At the rear solid discs measuring 249 x 9 mm are fitted. The 308 is equipped as standard with an ABS system, electronic brake force distribution (EBFD), and emergency brake assist (EBA). Automatic illumination of the hazard warning lights in the event of sharp deceleration completes the specification. The ESP, as standard or optional according to versions, adds to these functions: traction control (ASR) and stability control (CDS). It can be disconnected for enhanced traction on difficult road surfaces and is reconnected automatically above a speed of 50 kph.

Materials and recycling

The 308 complies with European directive 2000/53/EC on processing end of life vehicles to ensure this result, steps were taken concerning a number of criteria.

Choice of materials

Knowledge of the vehicle’s materials composition

The 308 anticipates the future recycling approval applicable at the end of 2008, which stipulates a fully exhaustive weight distribution of the materials that make up a vehicle. The 308 has benefited from the introduction of the MACSI application (Material Composition Information System) an IT system designed to determine the precise composition by weight and material of parts coming from our suppliers. 99 % of the weight of the 308 is composed of only five main categories of materials, most of which can be easily recycled or upgraded: metals, plastics, fluids, rubber and glass.

Prohibited and controlled substances

To ensure compliance with regulations (in particular European directive 2000/53/EC) concerning substances that are damaging to the environment (in particular heavy metals), particular attention has been paid to the different materials that make up the 308. Therefore, with the exception of some components that have an exemption (such as the battery) and which are subject to special processing at the end of the vehicle’s life, the 308 is free from cadmium, lead, hexavalent chromium and mercury.

The design of the vehicle

Three main principles guided the design of the 308 with regard to the environment: facilitating the removal of pollution from the vehicle at end of life Designing of the “drain� points of the tanks (fuel, windscreen washer fluid, etc.), together with optimised accessibility to them, makes it possible to guarantee complete draining; The electronic disarming of pyrotechnic devices ensures that the latter can be made safe quickly and protects recycling personnel; optimising the reclamation of materials Via the IDIS (International Dismantling Information System) database, the pollution removal and dismantling procedures are supplied to recycling professionals, in order to guarantee optimised processing; Plastic and rubber parts are marked to make them easier to identify and recycle; using parts made from recycled materials Some parts of the 308 use a proportion of recycled plastics, particularly mud flaps, the jack storage compartment and certain heat shields. In addition, in accordance with European Directive 2000/53/EC, Peugeot is also committed to informing the consumer about the various actions undertaken to encourage recycling of the vehicle.

Important measures for ambitious quality targets

Industrial process

The 308 assembly lines at the Sochaux and Mulhouse sites have been designed and planned to ensure maximum build quality. For the panel and metalwork, each vehicle is checked by laser cameras to ensure the perfect geometrical accuracy determined for the car’s specification. During assembly, where 75 % of components are assembled by hand, special attention is paid to workstation ergonomics and personnel training to guarantee the best possible results. At every stage, quality inspections, particularly strict with regard to tolerance intervals, have been multiplied and made more stringent. In addition, the two phase launch strategy of the 308 range allows better control of the industrial process as production lines build up speed, ensuring maximum quality as the very first cars roll off the production lines. The first models to be launched will include the “basic range� of the 308 programme: the four main engines with manual gearboxes, the five door model and the Premium, Premium Pack and Féline levels of finish.

Tests

Peugeot, in accordance with the quality improvements stipulated by the Group’s new management, an extended test mileage programme was undertaken as part of the T7 development programme. 2,000,000 km or double the normal mileage programme has been completed before the launch of the car. The aim was to obtain as much feedback as possible with a view to improving or correcting the slightest detail to ensure the 308 meets the stringent quality objectives set for it.

Total cost of ownership

The vehicle’s operating costs and its residual value (forecasting of resale price after a specific period of time) are factors of great importance to some customers when they buy their car and are decisive for their satisfaction and their loyalty. This is particularly true of fleet customers, who represent a not insignificant share of the compact saloon segment. Factors directly influencing these were considered throughout the development of the 308. All of these points will impact positively on the residual value of the 308. The appeal of the Peugeot 308, through its style and its specification, i.e. by the attractiveness and image it generates, will condition a part of this residual value and therefore its total cost of ownership.

The 308… coming next…

The 308 programme as a whole evidently includes a large number of projects. Several body shapes will therefore be launched over the coming months and years. Even if some can already be guessed at, each will surprise its public when the time is right. In terms of engines and transmissions, the year 2008 will be rich in events for the 308 with, in particular, the launch of a “BioFlex� petrol model. In this way Peugeot is keen to be in at the start of the bio-fuel market. This proposal will enable the car to be driven with a fuel composed of up to 85 % ethanol. Note that today, all HDi diesel engines in the Peugeot range, operated within a captive fleet, can run without any modification a mix of 30 % biodiesel. As part of the research and development programme concerning HDi Hybrid technology, the 308 is the first vehicle which could one day benefit from this, should its cost/economy ratio prove favourable to customers. This technology, combines the thermodynamic advantages of an HDi diesel engine with those of an additional electric motor which is designed to operate at low speed, will allow a gain in fuel consumption of around 30 %.
