"The Exelero project is actually a joint venture between Maybach and German tire manufacturer Fulda. Fulda has been making all sorts of high-performance rubber for almost a century, and is well known for using high-profile one-off vehicles to advertise itself. Past vehicles include high-speed buses, special trucks and racing cars. Oh yeah, Fulda also once used a super streamlined Maybach to test high-speed tires (over 200 kph) way back in 1938.

As you well know, car and tire technology has changed a lot, so Maybach and Fulda can't just rebuild a mere 200 kph (148 mph) car and call it a day. Fulda needs a car to test its 315/25ZR23 tire that is capable of speed of over 350 kph (217 mph). For those of you not literate in reading tire sizes: this tire will fit a 23-inch rim, be 313 millimeters wide (or over a foot wide) with a super-low profile sidewall. More importantly: this tire is not designed for race cars it's designed for standard street legal ride. Well, a street-legal ride that can go almost 220 miles per hour.

This optimized Maybach Type 12 engine is capable of making 700 brake horsepower and 1,000 newton meters (737 lb.-ft.) of torque. Obviously, those are some very impressive power numbers, but how does the car perform? Well, the Maybach Excelero was able to achieve a top speed of 351.45 kph (or about 218 mph). "

Maybach er vel mercedes sitt tidligeere super/luksus merke, lansert det igjen på geneve utstillingen for noen år siden. De hadden en mørk bil i ett klassmonter som det nesten var umulig å se igjennom, så lyste de opp en del av bilen av gangen, fikk ikke mulighet til å se hele. Jeg sto der lenge...

Tror ikke de har noen planer om å produsere bilen i flere eksemplaner, hvis du ønsket å kjøpe den...

Som sainsbury sier så er dette kun en engangs modell fra Maybach! På spesial bestilling fra superdekk-produsenten Fulda, brukt som reklame for sine nye høyhastighets-dekk, godkjent for 350km/t + :D

Det er altså ikke snakk om noen "ny, egen maybach-coupe" som skal settes i masse produksjon :(

Maybach Exelero er en utrolig tøff bil, den er en slik vi kan hvos vi vil bil fra DCAG, her er utdrag fra pressemeldingen om bilen:

The project Exelero - the legend lives

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

Stuttgart, May 18, 2005

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.

Greatest challenge to technology and material - TÜV inspection approves test start

Stuttgart, May 18, 2005

Sunday, 1 May 2005, 5.45 hrs., sunrise in a radiantly blue Southern Italian sky. The atmosphere is tense on Nardo’s 12.5-kilometer circuit. Klaus Ludwig, a three-time DTM winner sits in his racing gear and helmet, apparently completely calm, at the wheel of the Maybach Exelero and waits for the signal to start in his attempt on the record.

This highlight of the project had been preceded by a number of intensive tests, starting with the various wind tunnel phases. In accordance with the results, the Exelero was optimized correspondingly.

Then in March came the roll-out in Turin where the Maybach Exelero was officially handed over to the client, Fulda Reifen.

In mid-April, it then went to the so-called "running-in track” at the Sindelfingen plant. Here, the vehicle was subjected to intensive checks of its engine functions, brakes, chassis and handling etc., already at speeds of around 200 km/h.

Finally, at the end of April, the technical inspection of the Exelero was carried out on the DaimlerChrysler test track in Papenburg, i.e. the test measurements conducted provided the basis for preparations for the attempt at the high speed record in Nardo. For example, Spoilers were tried out in various positions and further adjustments made to optimize the speed and stability.

Since the Exelero vehicle is intended to prove itself in the long run in practical use, it was appropriately designed as a road machine and needed a license. That meant that the TÜV (Technical Control Board) had to give its technical blessing to the Exelero. Peter Kühlwein, one of the most experienced experts of TÜV Automotive GmbH, Gruppe Süd, tested and evaluated the safety-relevant vehicle components like the seats with the safety belts and the weight distribution within the car. All points were checked off to the satisfaction of the TÜV engineer or otherwise reconfigured.

When all the reservations from the side of the DaimlerChrysler specialists, the tire engineers and the TÜV experts, had been satisfied, nothing stood in the way of the final mission in Southern Italy.

The entire team already arrived on Thursday. On this day and the next, the Exelero was completely checked yet again. On Saturday the team checked all the measuring facilities and conducted trial measurements as well as several test laps with technical project manager Jürgen Weissinger at the wheel. Early on Sunday morning then everything was ready: The final test could begin.

At 7.09 hrs., Klaus Ludwig already completed his first lap at a speed of 346 km/h. Just one lap later the targeted record of 350 was broken. The FIA standardized measuring unit registered a world record top speed of 351.45 km/h! Klaus Ludwig’s comments after breaking the record: "It was unbelievable how easily the vehicle could be handled at this record speed. Particularly the tires conveyed an absolutely safe feeling. Everything was simply just right: technology, chassis and tires."

Bernd J. Hoffmann, Managing Director of Fulda Reifen, thanked all the teams involved for their outstanding efforts: "Everybody gave their best and thus made this success possible. The vehicle and tires supplement each other perfectly."

An idea becomes reality.
