Three powerful world premieres by AMG

 

Mercedes-AMG is presenting three exciting high-performance products at the 61st Frankfurt Motor Show (IAA): the ML 63 AMG, the "Vision R 63 AMG" and the AMG 6.3-litre V8 engine. With these three world premieres, the DaimlerChrysler Group's high-performance division is demonstrating both its special status and its expertise in the development of exceptional vehicles and high-performance engines.

The Mercedes-Benz ML 63 AMG is the new benchmark among sporty off-roaders. Powered by the 375 kW/510 hp AMG 6.3-litre V8 engine, the new top-of-the-line M-Class model heads the competitive line-up and delivers the performance levels of a sports car: acceleration from zero to 100 km/h in just 5.0 seconds, with a maximum speed of 250 km/h (electronically limited). This new off-roader developed by Mercedes-AMG represents sportiness and dynamism at the highest level, while its exclusive appointments meet the expectations of even the most demanding customers.

The "Vision R 63 AMG" is a particularly dynamic, near-series interpretation of the new Mercedes-Benz R-Class, the Grand Sports Tourer. Powered by the all-new, completely independently developed AMG 6.3-litre V8 engine with an output of 375 kW/510 hp and a maximum torque of 630 newton metres, the "Vision R 63 AMG" represents an unprecedented combination of unique, sporty driving pleasure, outstanding spaciousness and top-class comfort for up to six occupants.

Alongside the series-production version of the new Mercedes-Benz R-Class, whose short wheelbase variant is celebrating its world premiere at the show, the "Vision R 63 AMG" with a long wheelbase, an avantgarde design and an extravagantly styled interior, will appear in the role of a sporty and dynamic trendsetter. This Mercedes-AMG interpretation of the Grand Sports Tourer confirms its exceptional position in the automotive market right from the very first glance. Externally, numerous details distinguish the muscular showcar from the series-production R-Class. The bodywork of the "Vision R 63 AMG" is resplendent in "dark titanium grey", whilst the external trim is in matt titanium grey. Newly designed front and rear aprons in the typical AMG look, bi-xenon headlamps with titanium-coated reflectors and the two twin chromed tailpipes of the AMG sports exhaust system convey unmistakable dynamism. Massive, matt titanium-painted 21-inch AMG light-alloy wheels in a 5-spoke design with 265/40 R 21 wide-base tyres all-round lend a striking effect to the side view of the almost 5.20-metre long Grand Sports Tourer. Behind the spokes of the AMG light-alloy wheels it is possible to discern the generously dimensioned AMG high-performance braking system, which ensures extremely short braking distances.

Sports-car performance from the "Vision R 63 AMG"

The new AMG 6.3-litre V8 engine provides the performance characteristics of a thoroughbred sports car. With an output of 375 kW/510 hp and 630 newton metres of torque, the newly-developed, large-displacement naturally aspirated AMG eight-cylinder engine makes for a supremely assured and dynamic driving experience. The "Vision R 63 AMG" accelerates to 100 km/h in approximately five seconds and has a maximum speed of 250 km/h (electronically limited). Power is transferred by an AMG SPEEDSHIFT automatic transmission with steering wheel gearshift paddles and a DIRECT SELECT shift lever. A combination of permanent all-wheel drive with a torque distribution of 40:60 between the front and rear axles, an AMG sports suspension based on the AIRMATIC air suspension with the Adaptive Damping System ensures the greatest possible handling safety and - at the touch of a button - allows a dynamic or more sporty style of driving.

The interior of the "Vision R 63 AMG" is impressively spacious, with a stylish colour scheme and luxurious appointments. Two-tone nappa leather, AMG sports seats in the first two seat rows, the AMG ergonomic sports steering wheel with gearshift paddles and the AMG instrument cluster convey sporty flair. Matching the exterior of the AMG showcar, most of the decorative trim in the interior features a matt titanium grey finish - complemented by trim in black piano lacquer on the front centre console. Thanks to a DVD player, passengers in the second and third rows are able to enjoy their own programme of entertainment in the "Vision R 63 AMG". Four 7-inch TFT flat-screen monitors are integrated into the head restraints of the front seats. For optimum convenience and a relaxed journey there are two folding tables for the individual centre seats, as well as the multi-zone THERMOTRONIC climate control system which ensures a pleasant interior climate for all six occupants.

ML 63 AMG: New benchmark among sporty off-roaders

Equipped with the 375 kW/510 hp AMG 6.3-litre V8 engine, the new top-of-the-range M-Class model occupies the peak position in its segment and sets a new standard among sporty off-roaders. The powerful heart of a high-performance athlete beats beneath the bonnet of the ML 63 AMG: a completely new unit, developed entirely by Mercedes-AMG, the AMG 6.3-litre V8 engine generates an output of 375 kW/510 hp at 6800 rpm and a maximum torque of 630 newton metres at 5200 rpm. This makes the new AMG powerpack the world's most powerful naturally aspirated V8 engine in terms of specific output and specific torque.

This unique combination of a high-revving engine design and a large displacement offers the best of both worlds: exhilarating liveliness accompanied by powerful torque from low engine speeds. The driver of the ML 63 AMG experiences the decidedly sporty character of the new AMG V8 engine as tremendous agility and dynamic responsiveness in all engine speed ranges.

The leader in displacement and performance

No other off-roader in the direct competitive line-up has a larger displacement and output than the new ML 63 AMG. The AMG 6.3-litre V8 engine provides the performance levels of a sports car, with acceleration from zero to 100 km/h in just 5.0 seconds and a maximum speed of 250 km/h (electronically limited). Compared to the preceding ML 55 AMG with 255 kW/347 hp and 510 newton metres, the new ML 63 AMG generates 46 percent more output and 23 percent more torque.

Power transfer in the top M-Class model is via an AMG SPEEDSHIFT 7G-TRONIC automatic transmission with a DIRECT SELECT shift lever mounted on the steering column. Three shift modes specially configured for the sporty performance characteristics of the AMG V8 engine ensure that the power is used to best effect. These shift modes - "S" (Sport), "C" (Comfort) and "M" (Manual) - are selected using a switch in the centre console and differ in their gearshift characteristics and speed.

As in a Formula One racing car, the seven gears can be changed using the gearshift buttons on the AMG ergonomic sports steering wheel. The permanent all-wheel drive of the ML 63 AMG is also configured for sporty performance: in the interests of the best possible agility and performance on bends, the generous power of the AMG V8 engine is distributed to the front and rear axles on a 40:60 basis. A specially strengthened drive train ensures an optimal power transfer and characteristic Mercedes reliability.

AMG sports suspension and AMG high-performance braking system

The AMG sports suspension based on AIRMATIC ensures high cornering speeds, precise directional stability and low levels of body roll while providing excellent long-distance comfort. The air suspension features AMG-specific damper struts and a specially configured version of the Adaptive Damping System (ADS). A level control system automatically lowers the suspension at higher speeds.

Road contact is via high-sheen 19-inch AMG light-alloy wheels in a 5-spoke design. Featuring 295/45 R 19 wide-base tyres all-round, this wheel/tyre combination is not only impressive for its muscular appearance, but also gives the car the roadholding it needs for sporty performance. High-sheen 20-inch AMG light-alloy wheels in a five-spoke design with 295/40 R 20 wide-base tyres are available as an option. The shortest possible braking distances are ensured by the generously dimensioned AMG high-performance braking system, which features internally ventilated and dimpled brake discs all-round.

Striking appearance with AMG styling and flared wings

Wide, muscular, with a broad stance and poised to surge forward - the visual appearance of the new ML 63 AMG leaves no doubt that this is an exceptional vehicle. The athletic design of this powerful off-roader is characterised by its striking AMG bodystyling with a front and rear apron, an AMG-specific radiator grille, flared wings, stainless steel running boards with rubber studs and tinted rear lights. Both visually and acoustically, the AMG sports exhaust system with two chromed twin tailpipes emphasises the power and dynamism of the top-of-the-range M-Class model.

Dynamically designed interior with exclusive standard appointments

Sportiness is the dominant theme in the interior of the ML 63 AMG too. The exclusive interior features include AMG sports seats with nappa leather upholstery, Alcantara inserts in the shoulder areas, a multicontour function and heating, the AMG ergonomic leather sports steering wheel with gearshift buttons, AMG door sills and stainless steel sports pedals with rubber studs. The AMG instrument cluster is equally dynamic with its specially styled markings, red needles and 320 km/h speedometer scale.

The ML 63 AMG also meets the highest requirements in terms of safety: standard safety features include the anticipatory occupant protection system PRE-SAFE®, crash-responsive NECK-PRO head restraints in the first seat row, adaptive, two-stage airbags for the driver and front passenger, front sidebags, windowbags and belt tensioners with belt force limiters for all the seats. Following the world premiere at the Frankfurt Motor Show (IAA), the official market launch of the ML 63 AMG will take place during the second quarter of 2006.

AMG 6.3-litre V8 engine: high-revving design and large displacement

Mercedes-AMG has taken a completely new line in drive technology: the new AMG 6.3-litre V8 engine is the first in the world to combine a high-revving design with a large displacement. Developed entirely by AMG, this high-performance engine has a displacement of 6.3 litres and generates an output of 375 kW/510 hp at 6800 rpm with a maximum torque of 630 newton metres, which makes the new powerpack by AMG the world's most powerful naturally aspirated V8 engine in terms of specific output and specific torque. Thanks to its large displacement, the V8 by AMG develops around 20 percent more torque than comparable naturally aspirated engines in this output class.

This unique combination of a high-revving design with a large displacement offers the best of both worlds: exhilarating liveliness and high torque at low engine speeds. For the AMG driver the result is lively, ultra-spontaneous response. The high agility, the exciting, fast-revving characteristics and the high torque are very noticeable in all engine speed ranges. The new AMG V8 already delivers 500 newton metres to the crankshaft at 2000 rpm, and the maximum torque of 630 newton metres is available at 5200 rpm - more than any other naturally aspirated engine in this output and displacement class.

Aluminium V8 engine with motorsport technology

Made completely from high-strength aluminium, this naturally aspirated V8 engine has a wealth of exciting features derived from motorsport, and stands as an impressive reference to the successful motor racing history of AMG. Together with a variable intake manifold featuring two integral throttle flaps, the vertical arrangement of the intake and exhaust ducts ensures optimum cylinder charging. Bucket tappets in the cylinder heads allow a stiff valve train and therefore high engine speeds. Variable camshaft adjustment, a particularly rigid closed-deck crankcase and cylinder walls with a new, revolutionary LDS coating are further attributes of this ultra-modern Mercedes-AMG V8 engine.

For the crankcase, the engineers and technicians opted for a particularly rigid bedplate design with closed-deck technology. Special, cast-in steel components ensure even more rigidity, a reliable oil supply in all day-to-day operating situations and optimum long-term durability.

The new powerpack is produced at the ultra-modern AMG engine facility, according to the "one man, one engine" philosophy. This means that a single specialist assembles the complete engine by hand. To reflect this, the engine's AMG badge bears the specialist's signature.

ML 63 AMG

 

Pole position in the off-road segment

The Mercedes-Benz ML 63 AMG is the new benchmark in the sporty off-roader segment. With its 375 kW/510 hp AMG 6.3-litre V8 engine, the new top-of-the–range M-Class model heads its competitive segment. This new off-roader developed by Mercedes-AMG stands for sportiness and dynamism at the highest level, while its exclusive appointments meet even the most exacting requirements. The muscular design of the ML 63 AMG is visual confirmation of the car's exceptional position. The new high-performance off-roader will be launched during the second quarter of 2006.

The powerful heart of a high-performance athlete beats beneath the bonnet of the ML 63 AMG: a completely new unit, developed entirely by Mercedes-AMG, the AMG 6.3-litre V8 engine generates an output of 375 kW/510 hp at 6800 rpm and a maximum torque of 630 newton metres at 5200 rpm. This makes the new AMG powerpack the world’s most powerful naturally aspirated V8 engine in terms of specific output and specific torque. Thanks to its large displacement, the new V8 by AMG generates approx. 20 percent more torque than comparable naturally aspirated engines in this output class.

Unique combination of a high-revving design and large displacement

This unique combination of a high-revving engine design and a large displacement offers the best of both worlds: exhilarating liveliness accompanied by powerful torque from low engine speeds. The driver of the ML 63 AMG experiences the decidedly sporty character of the new AMG V8 engine as tremendous agility and dynamic responsiveness in all engine speed ranges.

Naturally aspirated aluminium V8 engine with a wealth of motorsport technology

Made completely from high-strength aluminium, this naturally aspirated V8 engine has a wealth of exciting features derived from motorsport and stands an impressive reference to the successful motor racing history of AMG. Together with a variable intake manifold featuring two integral throttle flaps, the vertical arrangement of the intake and exhaust ducts ensures optimum cylinder charging. Bucket tappets in the cylinder heads allow a stiff valve train and therefore high engine speeds.

Variable camshaft adjustment, a particularly rigid closed-deck crankcase and cylinder walls with a new, revolutionary LDS coating are further attributes of this ultra-modern Mercedes-AMG V8 engine. The electronically controlled fuel supply system with newly developed components operates on a demand basis with a system pressure of 3.8 to 5.0 bar. The fuel pressure is variably and instantly adjusted depending on the performance requirement and ambient temperature. The engine electronics execute commands from the accelerator pedal within milliseconds to set the required pressure. This control system ensures outstanding responsiveness and sporty performance in all load and engine speed ranges.

Patented oil and water cooling with separate heat exchangers

The entire cooling system in the new ML 63 AMG is also a new design. A high-performance water cooler ensures an efficient cooling performance under all operating conditions, while large engine and transmission oil coolers help to cool the lubricants effectively. Optimal efficiency is also guaranteed by a technology for which Mercedes-AMG has registered a patent. Intelligent coupling of the water and oil circuits enables the performance of both systems to be variably controlled. The major component is a DC heat exchanger which links the two circuits. If the engine oil temperature increases markedly, e.g. when driving briskly on mountain roads, the engine electronics activate an additional water pump to increase the rate of coolant flow in the heat exchanger. In this way the temperature difference between the engine oil and coolant ensures a cooling effect on the engine oil throughout the system. At high ambient temperatures this effect is increased by the large ram-air-vent-controlled suction-type fan of the water cooler, with an output of 850 Watts.

AMG sports exhaust system with enlarged pipe cross-sections

Under acceleration, the driver of the ML 63 AMG experiences the exhilarating sound of the high-revving engine – courtesy of the all-new AMG sports exhaust system - and the extraordinary power of the naturally aspirated eight-cylinder engine. Needless to say, this smooth-running powerpack also ensures effortless progress at constant motorway speeds. In conjunction with some highly sophisticated engine technology, the AMG sports exhaust system ensures effective emissions control. The new AMG high-performance off-roader meets not only the EU-4 standard but also the stringent current and planned US exhaust emission limits.

Continuous camshaft adjustment makes a major contribution to efficient emissions control. The engineers at AMG have used the principle of valve overlap to achieve a dual advantage, since reducing gas cycle losses cuts both untreated emissions and fuel consumption. The afterburning effect of the secondary air injection system results in higher exhaust gas temperatures and supports the heating-up process. As a result of this complex system the carbon monoxide and hydrocarbon content in the untreated exhaust gases is reduced. The lambda sensors continuously monitor the constituents of the mixture and supply this information to the computer, which readjusts the mixture.

Sophisticated exhaust technology with four ceramic catalytic converters

The new AMG V8 engine also has a demand-related lambda control system. This means that in all operating conditions, the constituents of the intake mixture can be precisely controlled to avoid damaging the catalytic converters. This also benefits the fuel consumption under full load, as the mixture can be leaner than in engines without this intelligent control system. Four lambda sensors are used to control and monitor the exhaust system: the two upstream sensors ensure an optimal control range, while the downstream sensors are responsible for Onboard Diagnosis II.

Effective aftertreatment begins in the air-gap-insulated manifolds, which have a wall thickness of only 1.0 millimetres. Tens seconds after starting, these already allow an exhaust temperature of 280 degrees Celsius – a precondition for rapid response by the close-coupled catalytic converters. All four ceramic catalytic converters feature thin-wall substrates; thanks to their maximised surface area these not only provide the best conditions for effective emissions control, but also aid performance with their low exhaust backpressure. Large exhaust pipes with a generous diameter of up to 70 millimetres enhance this effect still further. The two oval, chromed twin tailpipes provide a striking note – both visually and acoustically.

AMG SPEEDSHIFT 7G-TRONIC automatic transmission with steering wheel gearshift

Power transfer in the top M-Class model is via an AMG SPEEDSHIFT 7G-TRONIC automatic transmission with a DIRECT SELECT shift lever mounted on the steering column. The seven gears are finely graduated in the interests of a sporty response. Torque converter lockup from first gear further improves dynamism and efficiency, as it reduces slip losses. As in a Formula One racing car, the seven gears of the ML 63 AMG can be shifted using the gearshift buttons on the AMG ergonomic sports steering wheel.

The AMG SPEEDSHIFT 7G-TRONIC transmission adapts to both a dynamic and a more comfortable style of driving. Three shift modes specially configured for the sporty performance characteristics of the AMG V8 engine ensure that the power is used to best effect. These shift modes - "S" (Sport), "C" (Comfort) and "M" (Manual) – are selected using a switch in the centre console and differ in their gearshift characteristics. In the manual "M" mode the driver gets additional benefit from the high torque of the V8 engine, as the transmission does not perform an automatic downshift under full load or during kickdown, but rather remains reliably in the selected gear. Neither does AMG SPEEDSHIFT perform an automatic upshift when the engine speed limit is reached in manual mode. This means that particularly sporty drivers are able to make even fuller use of the effortless performance potential.

Permanent all-wheel drive with 40:60 torque distribution

The permanent all-wheel drive of the ML 63 AMG also has a decidedly sporty configuration: in the interests of optimal agility and cornering dynamics, the extraordinary power of the AMG V8 engine is distributed to the front and rear axles on a 40:60 basis. The transfer case is directly flanged to the 7G-TRONIC transmission. Propeller shafts transfer power to the front and rear axles, while a bevel differential compensates for differences in speed between the axles.

A heavier-duty drive train ensures the optimum power transfer and typical Mercedes reliability, with larger wheel carriers, wheel bearings and lower supporting joints at the front axle. A rigid connection between the front subframe and the bodyshell also ensures greater steering precision when negotiating bends. At the rear axle, strengthened components are used for the hydro-mounts of the wishbones, the wheel flanges, half-shaft joints and differential cage.

Traction control in the ML 63 AMG is by means of the well-proven Electronic Tractions System 4ETS, which now has additional functions and is even more effective than before. 4ETS controls the distribution of torque to the wheels by using the signals received from the ABS wheel sensors to trigger brief braking pulses. If these sensors report that one or more wheels have lost their traction, they are automatically braked. At the same time the distribution of drive torque is changed: the torque fed to the wheels with good traction is increased in line with the braking effect on the spinning wheels, allowing progress to continue on loose or slippery ground.

Newly developed AMG sports suspension based on the AIRMATIC package

The AMG sports suspension based on AIRMATIC ensures high cornering speeds, precise directional stability and low levels of body roll while providing excellent long-distance comfort. The air suspension features AMG-specific damper struts and a specially configured version of the Adaptive Damping System (ADS). Both the air springs and dampers have a considerably stiffer set-up. AMG shock absorbers with modified characteristics in all three stages reduce body movements, while larger torsion bar stabilisers at both axles reduce body roll when cornering at speed.

The system operates on a speed-related basis, automatically lowering the suspension by 15 millimetres when a speed of 140 km/h is reached to reduce wind resistance and improve handling stability. The suspension is returned to its normal level when the speed drops below 40 km/h. Other features of the air suspension system include automatic all-round level control. This ensures the same degree of suspension travel even when the vehicle is heavily loaded. For off-road journeys, this system allows the ground clearance to be increased by 70 millimetres at the touch of a button. The body can be raised and lowered either when idling or on the move.

Adaptive shock absorber control in line with the driving situation

The AMG sports suspension works together with the Adaptive Damping System (ADS), which controls the shock absorber response in line with requirements while taking the road surface, driving style and load into consideration. Switchable solenoid valves in the shock absorbers enable the rebound and compression damping to be modified according to the situation, which considerably reduces body movements. The 'skyhook algorithm' controls the damping forces at each wheel in such a way that the wheel-induced forces acting on the vehicle body are reduced. Thanks to this precise control for each individual wheel it is possible, for instance for the two front wheels to be damped more heavily than the rear wheels to reduce the tendency of the body to dive when braking. Depending on the control command, the valves select one of four characteristic curves within an extremely short response time of less than 0.05 seconds:

When body movements are small the ML 63 AMG operates in ADS stage 1. If body acceleration values exceed a certain level, the system changes over to the skyhook algorithm and uses its rapid-response solenoid valves to continuously switch between the second and third damping stage to suppress the rolling and pitching movements of the vehicle body. The current driving situation is identified by means of a steering angle sensor, three body-mounted acceleration sensors, four wheel-mounted level sensors, further data from the Electronic Stability Program (ESP®) and signals from the engine and transmission control systems. On the basis of this information the electronic control unit calculates the most efficient damping forces and selects the relevant characteristic curves for the shock absorbers.

In addition the driver is able to influence the changeover thresholds between the four ADS stages at the touch of a button on the centre console. There is a choice of three modes: "Auto", "Sport" and "Comfort".

Speed-related power steering with variable assistance

Thanks to its direct steering ratio, the standard speed-dependent power steering ensures precise handling in any driving situation. At speeds below 100 km/h its servo assistance is automatically increased in the interests of reduced steering effort. The servo effect is gradually reduced above this threshold value, improving the driver's feel for the road. A newly developed, highly efficient steering cooler ensures that the power steering functions reliably even when subjected to high dynamic stresses. This cooler is located behind the AMG front apron and integrated into the radiator package to save space.

19-inch AMG light-alloy wheels and an AMG high-performance braking system

Road contact is via high-sheen, 9.5-inch wide, 19-inch AMG light-alloy wheels in a 5-spoke design. Featuring 295/45 R 19 wide-base tyres all-round, this wheel/tyre combination is not only impressive for its muscular appearance, but also gives the car the roadholding it needs for sporty performance. High-sheen 20-inch AMG light-alloy wheels in a five-spoke design with 295/40 R 20 wide-base tyres are available as an option. The best possible deceleration, sensitivity and fade-resistance is guaranteed by the AMG high-performance braking system. Internally ventilated and dimpled brake discs all-round, measuring 390 x 36 millimetres (front) and 365 x 26 millimetres (rear) guarantee outstanding thermal resistance.

Vision R 63 AMG

 

Particularly dynamic, near-series interpretation of the new Mercedes-Benz Grand Sports Tourer

Output and torque in abundance, an exclusive appearance and first-class travelling comfort are key attributes of the "Vision R 63 AMG", a particularly dynamic, near-series interpretation of the new Mercedes-Benz R-Class. This AMG showcar is the crowning glory of a unique concept developed by Mercedes-Benz, which combines the advantages of familiar vehicle types such as sporty luxury saloons, estates, MPVs and SUVs.

The Grand Sports Tourer made by Mercedes-AMG is powered by the all-new, completely independently developed AMG 6.3-litre V8 engine with an output of 375 kW/510 hp and a maximum torque of 630 newton metres, producing the performance levels of a sports car. Featuring permanent all-wheel drive, an AMG sports suspension based on the AIRMATIC air suspension system, and the AMG SPEEDSHIFT seven-speed automatic transmission with gearshift paddles, the "Vision R 63 AMG" guarantees its six occupants a sporty driving experience of the highest order.

Alongside the series-production version of the new Mercedes-Benz R-Class, whose short wheelbase variant is celebrating its world premiere at the show, the "Vision R 63 AMG" with a long wheelbase, an avant-garde design and an extravagantly styled interior, will appear in the role of a sporty and dynamic trendsetter. An unrivalled power unit, generous spaciousness, top-class comfort and an impressive appearance are uniquely combined in a completely new interpretation.

Avant-garde exterior with dynamic highlights

The "Vision R 63 AMG" confirms its exceptional position in the automotive market right from the very first glance. Externally, numerous details distinguish the muscular showcar from the series-production R-Class. The bodywork of the almost 5.20-metre long "Vision R 63 AMG" is resplendent in "dark titanium grey", with all items of external trim in matt titanium grey rather than the standard shining chrome. These include the trim strips on the radiator grille, the circular foglamp surrounds in the front apron, all window surrounds, the door handle inserts and the boot handle. The newly designed front apron has the typical AMG look and features large air intakes with black expanded-mesh covers, an unmistakable indication of the extraordinary power residing in the new AMG 6.3-litre V8 engine. Bi-xenon headlamps with matt titanium coated reflectors and titanium-look indicators are further highlights. Sheer dynamism is suggested by the muscular rear apron with the two integral, chromed twin tailpipes of the AMG sports exhaust system.

Massive, matt titanium-painted 21-inch AMG light-alloy wheels in a 5-spoke design with 265/40 R 21 wide-base tyres fill the generous wheel arches and lend another striking aspect to the side view of the Grand Sports Tourer. Behind the spokes of the AMG light-alloy wheels it is possible to discern the generously dimensioned AMG high-performance braking system with internally ventilated discs all-round, which ensures extremely short braking distances and high fade resistance.

Sports-car performance thanks to an output of 375 kW/510 hp

The impressive bonnet of the "Vision R 63 AMG" conceals the new AMG 6.3-litre V8 engine. With an output of 375 kW/510 hp at 6800 rpm and 630 newton metres of torque at 5200 rpm, this newly-developed, large-displacement AMG V8 engine makes for a supremely assured and dynamic driving experience coupled with the performance potential of a thoroughbred sports car. It accelerates the Grand Sports Tourer to 100 km/h in approximately five seconds, with a maximum speed of 250 km/h (electronically limited).

Thanks to its large displacement, the world's most powerful naturally aspirated V8 engine in terms of specific output and specific torque generates around 20 percent more torque than comparable units in this output class. This unique combination of a high-revving design and a large displacement offers the best of both worlds: exhilarating liveliness accompanied by powerful torque at low engine speeds, as well as great agility and dynamic responsiveness in all engine speed ranges, are the typical attributes of this new AMG powerpack.

40:60 torque distribution for great agility

The "Vision R 63 AMG" has permanent all-wheel drive, with the power transferred to the front and rear axles on a 40:60 basis to ensure outstanding agility and cornering characteristics. Gearshifting is by the AMG SPEEDSHIFT seven-speed automatic transmission 7G-TRONIC with a DIRECT SELECT shift lever. DIRECT SELECT has enabled the transmission tunnel to be completely redesigned, the absence of a shift lever providing plenty of space for covered stowage compartments and a large cup holder.

The close spacing of the seven gears ensures that the optimum ratio is available, thereby optimising the sporty performance. As in a sports car, the seven gears can be changed by means of gearshift paddles on the AMG ergonomic sports steering wheel.

Three shift programmes for perfect driving pleasure

The AMG SPEEDSHIFT 7G-TRONIC transmission allows both a dynamic and a comfort-oriented style of driving. Three shift modes specially configured for the sporty performance characteristics of the AMG V8 engine ensure that the power is used to best effect. These shift modes - "S" (Sport), "C" (Comfort) and "M" (Manual) – are selected using a switch in the centre console and differ in their gearshift characteristics. In the manual "M" mode the driver gets additional benefit from the high torque of the V8 engine, as the transmission does not perform an automatic downshift under full load or during kickdown, but rather remains reliably in the selected gear. Neither does AMG SPEEDSHIFT perform an automatic upshift when the engine speed limit is reached in manual mode. This means that the more sporty driver is able to make even fuller use of the effortless performance potential.

AMG sports suspension based on AIRMATIC air suspension

The newly developed AMG sports suspension is based on the AIRMATIC system with the Adaptive Damping System (ADS) and allows the driver to select a dynamic or more comfortable suspension setting at the touch of a button, as required. There is a choice of three characteristic maps, and AIRMATIC also has an automatic level control function which lowers the suspension during fast motorway driving, thereby reducing air resistance.

Variable interior with an exclusive feel-good atmosphere

The variable interior of the "Vision R 63 AMG" impresses with its generous spaciousness, exceptional freedom of movement, stylish colour scheme and great opulence, with an immediate and exclusive feel-good atmosphere. Nappa leather for all six seats, a leather roof lining in metallic titanium and black leather on the door panels further enhance the exclusive look and feel, with colour-coordinated, double topstitching in titanium as a contrast. A sporty atmosphere is provided by the AMG sports seats in the first two rows and the AMG ergonomic sports steering wheel with gearshift paddles, plus an AMG instrument cluster with its specially styled markings, red pointers and a speedometer scale which extends up to 320 km/h. The large dial instruments projecting from circular, slightly inwardly inclined cylinders are framed by matt titanium surrounds, while an aluminium panel between them frames the multifunction display; it is also in matt titanium and bears the letters AMG.

Matching the external appearance of the AMG showcar, almost all the interior trim is finished in matt titanium grey - for example the trim strips on the instrument panel and doors, the trim parts and trim rings on the COMAND system, on the air conditioning control unit, on the steering-column stalks and the light switches, the door sills with the illuminated AMG logo, the rubber-studded sports pedals and the KEYLESS-GO starter button. As an elegant contrast the decorative trim on the front centre console is in black piano lacquer. The sophisticated interior of the showcar underlines the painstaking attention to detail with which AMG designers and technicians created the "Vision R 63 AMG". Hand-finished materials such as wood, leather and aluminium offer a feast for the senses, and a passion for precision is discernible everywhere in the luxurious interior.

The seats in the second row can be repositioned longitudinally and feature adjustable armrests for the best possible long-distance comfort. The single seats in both rear seat rows can be individually folded down as required, and the rear centre console is easily removable. This allows the interior to be adapted to suit with changing space requirements or transport tasks – carrying mountain-bikes, skis, snowboards or other recreational equipment is no problem. Even when the vehicle is carrying six occupants, there is still sufficient room to accommodate a large golf bag behind the third seat row.

With the rear seats folded down, the level loading surface has a length of 2217 millimetres measured from the front seat backrests to the tailgate. At a maximum of 2385 litres (acc. to VDA measuring method) when loaded to roof height, the loading volume exceeds the capacity of large estate cars. With the third seat row folded down, the "Vision R 63 AMG" has a maximum load capacity of 1067 litres.

Rear entertainment system with DVD player and four flat-screen monitors

Thanks to a DVD player, passengers in the second and third rows are able to enjoy their own programme of entertainment in the "Vision R 63 AMG". Four 7-inch TFT flat-screen monitors are integrated into the head restraints of the front seats. For optimum convenience and a relaxed journey there are two folding tables for the individual centre seats, as well as the multi-zone THERMOTRONIC climate control system which ensures a pleasant interior climate for all six occupants.

Panoramic sliding roof increases the feeling of spaciousness in the interior

The "Vision R 63 AMG" is also equipped with a panoramic sliding sunroof as standard, whose technology and size are unique. It provides a continuous area of glass extending from the windscreen to the rear aerial, and therefore allows a great deal of light into the interior even when closed. The result is an enhanced feeling of spaciousness and an even more enjoyable journey for the passengers. The transparent glass surface of the panoramic sliding roof is in line with the "XXL" dimensions of the Sports Tourer; it measures approx. 1.2 square metres, and is therefore roughly twice the size of a conventional sliding roof.

The panoramic sliding sunroof consists of two glass sections, of which the front section is movable. At the touch of a button the front section is raised and slides to the rear. The travel of the moving section takes place outside the vehicle body. This allows a larger roof aperture and ensures that the panoramic sliding sunroof does not restrict the headroom of the occupants. As in the case of a tilting/sliding roof, the moveable roof section can be adjusted to a tilted position. The panoramic sliding sunroof can also be operated by remote control, using the electronic ignition key. Electrically operated, perforated fabric roller blinds on the inside of the panoramic sliding roof provide effective protection from the sun when required.

Outstanding safety thanks to NECK-PRO head restraints, sidebags and windowbags

With two-stage front airbags and belt force limiters (front), belt-buckle and inertia-reel tensioners, sidebags and windowbags, the "Vision R 63 AMG" conforms to the high Mercedes-Benz standard in terms of occupant protection systems, too. Newly developed NECK-PRO head restraints optimise protection for the driver and front passenger in the event of a rear-end collision.

The AMG 6.3-litre V8

 

The world's most powerful naturally aspirated V8 engine in terms of specific output and specific torque– made by Mercedes-AMG

Mercedes-AMG has broken completely new ground: the new AMG 6.3-litre V8 engine is the first in the world to combine a high-revving design with a large displacement. Developed entirely by AMG, this high-performance engine has a displacement of 6.3 litres and generates an output of 375 kW/510 hp at 6800 rpm with a maximum torque of 630 newton metres, which makes the new powerpack by AMG the world’s most powerful naturally aspirated V8 engine in terms of specific output and specific torque. Thanks to its large displacement, the V8 by AMG develops around 20 percent more torque than comparable naturally aspirated engines in this output class.

Made completely from high-strength aluminium, this naturally aspirated V8 engine has a wealth of exciting features derived from motorsport, and stands as an impressive reference to the successful motor racing history of AMG. Together with a variable intake manifold featuring two integral throttle flaps, the vertical arrangement of the intake and exhaust ducts ensures optimum cylinder charging. Bucket tappets in the cylinder heads allow a stiff valve train and therefore high engine speeds. Variable camshaft adjustment, a particularly rigid closed-deck crankcase and cylinder walls with a new, revolutionary LDS coating are further attributes of this ultra-modern Mercedes-AMG V8 engine.

This eight-cylinder unit was developed to series production maturity exclusively by the engineers and technicians in Affalterbach. The AMG 6.3-litre V8 engine is celebrating its premiere in the new Mercedes-Benz ML 63 AMG, and will subsequently ensure rousing and sporty driving pleasure in further AMG models.

The high expectations of AMG customers and the impressive history of AMG eight-cylinder engines were both an incentive and an obligation for the engineers and product planners at Mercedes-AMG to come up with a superlative new V8 power unit. A mere glance at the key technical data shows that they have fulfilled their mission. From a displacement of 6208 cubic centimetres, the AMG V8 aluminium engine develops a peak output 375 kW/510 hp at 6800 rpm and a maximum torque of 630 newton metres which is available at 5200 rpm. The maximum engine speed is 7200 rpm.

This unique combination of a high-revving design with a large displacement offers the best of both worlds: exhilarating liveliness and high torque at low engine speeds. For the AMG driver the result is lively, ultra-spontaneous response. The high agility, the exciting, fast-revving characteristics and the high torque are very noticeable in all engine speed ranges. The new AMG V8 already delivers 500 newton metres to the crankshaft at 2000 rpm, and the maximum torque of 630 newton metres is available at 5200 rpm – figures which surpass those of any other naturally aspirated engine in this output and displacement class. In short, the new AMG eight-cylinder allows dynamic acceleration, rapid intermediate sprints and sheer driving pleasure at the highest level. With its new, sporty AMG exhaust note which was designed during an extensive series of tests, the eight-cylinder unit from Affalterbach offers the excitement of a high-revving V8 engine in unmistakable audible and tangible form at low, medium and high engine speeds.

Unique variable intake manifold and revolutionary cylinder walls

Aside from the large overall displacement, the extremely high output and torque are due above all to the sophisticated intake system. Here, AMG has taken a completely new approach. The major characteristics of this system are large cross-sections, the streamlined design of the entire intake and exhaust tracts, and the vertical arrangement of all ducts in line with the practice in the field of motorsport. Built from magnesium, the newly developed and patented variable intake manifold, which has two parallel-action internal throttle flaps, is a world first. Owing to the short distances between the throttle flaps and the combustion chambers, the combined action of these components, which are highly unusual in regular engine production, ensures dynamic responsiveness and optimum cylinder charging.

Revolutionary LDS-coated cylinder walls

The 32 valves in the cylinder heads are operated by bucket tappets, which allow stiff valve guidance and therefore high engine speeds. This is a familiar and very successful technology adopted from motor racing. Continuous adjustment of the camshafts on both the intake and exhaust sides is another special feature of this ultra-modern AMG V8 engine. The interior of this powerful new unit features a genuine world first: the AMG 6.3-litre V8 engine is the very first series production engine to feature a special LDS coating (twin wire arc spraying) on the cylinder walls, a new process which produces optimum low-friction characteristics.

Motor racing genes are recognisable in the crankcase, too: as in the supercharged AMG V8 engine for the Mercedes-Benz SLR McLaren, the engineers and technicians opted for a particularly rigid bedplate design with closed-deck technology. Special, cast-in steel components ensure even more rigidity, a reliable oil supply in all day-to-day operating situations and optimal long-term durability.

Completely independent development from Affalterbach

In design terms the new eight-cylinder engine by Mercedes-AMG is the first completely autonomous development, with no characteristics or components whatsoever in common with other eight-cylinder units by Mercedes-Benz. The new 6.3-litre unit differs from the other AMG V8 engines based on Mercedes designs in the distance between cylinders, the crankcase concept, the sophisticated intake and exhaust tracts and the valve train; the bore/stroke ratio is also a completely new departure for Mercedes-AMG.

The new powerpack is produced at the ultra-modern AMG engine facility, according to the "one man, one engine" philosophy. This means that a single specialist assembles the complete engine by hand. To reflect this, the engine’s AMG badge bears the specialist's signature.

Successful history of high-performance AMG engines

AMG engines have always been in a class of their own. The first highlight was the 6.8-litre, 309 kW/420 hp V8 racing engine in the legendary 300 SEL 6.8 AMG of 1971. At its first participation in the 24-hour race in Spa-Francorchamps this speedy Mercedes saloon secured a highly acclaimed class victory and took second place overall. Other milestones in the history of AMG included the first four-valve V8 (built in 1984), which generated 250 kW/340 hp from a displacement of five litres, and the 6.0-litre eight-cylinder unit with 283 kW/385 hp. The 368 kW/500 hp 5.5-litre, supercharged V8 engine in the SL 55 AMG, the supercharged AMG V8 engine generating 460 kW/626 hp in the Mercedes-Benz SLR McLaren and the AMG V12 biturbo engine with an output of 450 kW/612 hp and 1000 newton metres of torque are further highlights in the history of AMG engine technology.

In 2003 and 2004, the AMG 5.5-litre supercharged V8 and the AMG 6.0-litre V12 biturbo engine took first place against well-known competitors in the "Best Performance Engines" category of the "Engine of the Year Awards".
