The legend lives

 

The reinterpretation of automobile and tire technology of the ultra-high performance partners Maybach and Fulda

 

Just imagine an automobile that combines the elegance and first-class quality of a high-end limousine with the powerful suppleness of a sports coupé.

Create a vehicle in your mind's eye which, with an unladen weight of over 2.66 tons and the dimensions of a small transporter, achieves a maximum speed of over 350 km/h.

Conceive an ultra-high performance tire which not only copes with the aforementioned weight, the dimensions and the speed, but also makes the automobile safe, stable and comfortable.

Such a vehicle and such tires do not exist?

Now they do.

 

Always something special

 

For 99 years, Fulda has been making car tires. For most of this time, the company has advertised its products with special vehicles. Luxury buses, advertising vehicles with special bodies, high-speed buses for tire tests, a whole series of showtrucks, racing cars and - in the 1930s something quite special - streamlined car from the Maybach company which could conduct tire tests at speeds of over 200 km/h.

 

Unfortunately, not for too long, because the test car designed in 1938 and delivered in 1939 disappeared during the war years and never reappeared again.

 

66 years later: Fulda is introducing a new sophisticated high-tech tire to the market. For the most extreme dimension of this tire line, 315/25 ZR 23, licensed for speeds of more than 350 km/h, and that as a series tire, not a racing tire, what was needed was a high-speed vehicle but not a racing car.

A few years ago, one the most exclusive German automobile makes was revived, why not organize a joint project together once again, just like in the old days?

 

Cooperating with Maybach

 

The contacts were made and thanks to René Staud, a world-class photographer of automobiles and an outstanding "networker" of DaimlerChrysler and Fulda Reifen, they were purposefully and effectively developed. Following several coordinating discussions with Leon Hustinx, Maybach's manager, agreement was reached: Maybach would build a car for Fulda. Objective: to position the vehicle as an impressive ambassador for the new ultra-high performance tire generation Exelero.

 

An indispensable helper in the boat with the project partners: two professors and four students from Pforzheim Polytechnic's Dpartment of Transport Design. Together with the design professionals from DaimlerChrysler, under the direction of Professor Harald Leschke, the team went to work and after three-quarters of a year of promising design proposals, it was decided to realize the outline of the student Fredrik Burchhardt. He succeded in producing the most elegant symbiosis of design elements of former and present vehicle generations.

 

The model phase starts

 

Three model construction phases in the manufacture of a special vehicle are decisive in the development process:

·          the exterior design reference model (for the construction of the negative molds)

·          the interior reference model and

·          the chassis order with auxiliary frame.

 

Based on detailed and strict time schedules, all three phases were realized simultaneously. The well-known Italian vehicle study manufacturer Stola in Turin was commissioned by DaimlerChrysler to build the Exelero.

The sports coupé was also now given its final project name: Maybach Exelero.

 

On 31 May 2005 everything was ready. All three phases were completed. The 1:1 model for the exterior had been tested in the wind tunnel many times, modified and adapted. The interior details were fixed: natural leather, neoprene, coated punched aluminum sheet as well as carbon fiber in glossy black and red are the main materials. And the technicians who worked on the vehicle had arranged, rebuilt and made ready for use all the functions and the parts needed for this.

Dipl.-Ing. Jürgen Weissinger, the responsible project technician and development manager at Maybach, connected the battery, turned the ignition key and the car growled into life. The short burst of gas suggested record speeds.

 

The construction and test phase concluded with a outstanding success

 

Transforming a limousine, the basis for the Exelero is the Maybach 57, into a coupé is extremely demanding. Jürgen Weissinger and his team were astonished to find that, although the dimensions of the former SW 38 differed in the length (the Maybach 57 has a 290 millimeters longer wheelbase), in terms of breadth and height they were very similar. That simplified a whole series of structural measures.

 

When considering the engine alternatives, it soon became clear that the basic twelve-cylinder engine used in the Maybach limousines would not achieve the desired maximum speed of around 350 km/h despite the Biturbo turbo charger. Here, the Mercedes Car Group leapt into the breach. The engine specialists in Untertürkheim, the place where all basic engines are developed, provided energetic support for the project.

 

After several optimization of the Maybach type 12 engine, the cubic capacity was increased from 5.6 to 5.9 liters and the turbo charge optimized. The result was convincing: on the test bed almost 700 hp and at least 1,000 newton meters of torque were recorded, sufficient to achieve the targeted maximum speed of 350 km/h.

 

Before, during and after the aforementioned work, the individual evolutionary steps were supported by corresponding tests. Either on engine test beds in the plants or on test tracks like the high-speed oval in Nardo/Southern Italy or the test track in Cloppenburg.

 

The final test measurements at the end of April/beginning of May 2005, once again on the high speed Motodrom Nardo, then produced the well-earned success of lost of hard work: a top speed of 351,45 km/h - a world record for limousines - on standard tires.

 

And yet another world record: between the Fulda idea, the outstanding cooperation of all concerned and the delivery of the Maybach Exelero sports coupé, just 25 months passed.

 

Thanks to all cooperation partners

 

Yet again in Fulda Reifen's company history, a cooperation has led to an exceptional final result: a top-class product like the Exelero ultra-high performance tire is matched by an exceptional vehicle, unmatched anywhere else in the world, the Maybach Exelero sports coupé.

 

The result can never be the product of just one individual, only within the framework of a partnership at the highest level and the uncompromising efforts of all concerned can such a project succeed.

Fulda Reifen: dedicated to "high-performance" products

 

·          Long years of tradition in special vehicle construction

·          First high-speed tests with the streamlined Maybach in 1939

 

In the 1920s, the sales managers at Fulda Reifen, known at that time as Gummiwerke Fulda, were quite sure that the brand's image should not be communicated in isolation from the end-product that stands on four tires.

 

Consequently, they bought a bus, had it converted into a luxury coach and as of 1925, presented Fulda's new patented Parabel tire all over Germany and the neighboring countries. The first of a long series of special models was born.

 

Whether advertising vehicles equipped with record players and loudspeakers, the tail section shaped like huge tires, standing in front of the Reichstag in Berlin (1931), whether as a tire test streamlined bus with special license for speeds over 140 km/h (1961), or as a show truck series (from 1985) to demonstrate the respective latest high-tech truck tire generation - in all chapters of the Fulda company history there have been Fulda special vehicles.

 

The most challenging technical commission to produce a special model in the first half of the company's history with the simultaneous mysterious conclusion was awarded by Fulda in 1938. The starting point was the rapid development in automotive design in the 1930s which, due to the increasingly refined aerodynamic automobiles, permitted higher and higher speeds. In addition, the construction of the "Autobahn" provided motorists with the opportunity to travel further at higher speeds.

 

That was a challenge to the tire industry. Bernd J. Hoffmann, Managing Director of Fulda Reifen comments: "My pragmatic predecessors did not hesitate long: At Dörr & Schreck, a renowned vehicle-maker in Frankfurt, they commissioned the construction of a vehicle for tire tests. Precondition for this order was the assurance of the manufacturer that the vehicle could regularly make high-speed tests at more than 200 km/h."

 

Dörr & Schreck accepted the order and looked for the absolute leading cooperation partner in automobile manufacturing at that time: Maybach Motorenbau. Together and with the help of the well-known aerodynamic specialist, Freiherr Reinhard Koenig Fachsenfeld, they designed a three-seater streamlined car on the basis of a Maybach SW 38 chassis. The Fulda coupé with its two-color paint job and pontoon form had a long extended tail section sloping to the rear. From a bird's eye-view the overall line looked like a rectangle with rounded edges. The rear wheel arches were completely panelled, as was the underbody, even the door handles were partly recessed.

 

To reach the speed of over 200 km/h demanded by Fulda, the technicians installed a 6-cylinder engine with 140 hp. The exceptionally low air resistance coefficient of 0.25 (a figure of 0.6 was usual at that time for series-produced vehicles), also helped guarantee this speed. The precondition was, however, that the chassis did not exceed a weight of 1,600 kg.

 

On 27 July 1939, Dörr & Schreck finally announced the completion of the SW 38: "The car is extremely interesting and beautiful. It lies well on the road and the streamlined shape already makes itself felt at 60 km/h. Soon afterwards the car was delivered, but as a result of the outbreak of war its use was soon to be very limited. During the chaos of war the test vehicle disappeared and was never found again - its whereabouts remain a mystery to this day.

 

Looking back, it seems that the Fulda managers at that time could not foresee two future developments:

·          the imminent outbreak of war, which practically prevented the use of the coupé and

·          the emotional avalanche that the streamlined car triggered off several management generations later at Fulda Reifen.

 

An idea wins space.
