2007 MTM TT bimoto

07/24/07 – Record; 393km/h with bimoto. On Tuesday morning, the mtm TT bimoto hit a new top speed of 393km/h setting a new official record for the top speed on the test track in Papenburg.

The 2 engine vehicle Bimoto was driven by the current champion of the Seat Supercopa 2006 Florian Gruber who is also currently driving in the Porsche Carrera Cup.

The bimoto record ride was achieved in the second run of two trails, under windy conditions, partial rain and temperatures of around 20 degree Centigrade, The trials are intended as pre- tests for runs in Nardo/ltaly where with the support from our sponsors Rhino’s Energy Drink, Agip Germany, KW automotive GmbH / LSD GmbH and Continental, the Bimoto is set to beat the magic mark of 400 km/h.

The story

The mtm Bimoto, probably the most impressive vehicle produced by mtm, is based on the Audi TT and is equipped with two four cylinder turbo-engine. Even the starting performance makes overwhelming driving powers possible. Because of further engine-modifications together is a maximum 1000 HP possible.
The latest project – the mtm bimoto – is one of the exclusive and extraordinary special vehicles of mtm. Once more it shows that the founder Roland Mayer wants more engine power and perfection.

Mercedes made a similar study (two engines in a A 190) with 15 employees in 4 months which means 60 work-hours in a month, mtm developed the TT bimoto in only 50 work-hours. The idea of two engines sounds strange at first, but it has lots of advantages compared with other ideas. To construct a vee eight turboengine for example we would have had to choose a central engine arrangement, which would have required the development of a special and more expensive allroad transmission.

For the drive of his two axles the mtm bimoto has two engines and two transmissions. Below the slightly changed body of the Audi TT hides more than expected at first sight. Both in front and rear every transmission is driven by its own 1.8 I four cylinder turbo-engine. A partition made of carbon including a rear window separates the maximum two passengers from the second drive unit in the rear. What you can find in it is that almost every component is doubled like the front one. Likewise there is a manual six gear transmission installed on the opposite of the driven direction which is driven by a 1.8 I cylinder in almost he same axis of the front part. To make power shifts possible double-clutches-transmissions will be obstructed in the new future. A welded cage stabilizes the complete car and includes the both aggregates.

The engines in the rear and in front move independently. The power comes from the street which is the connecting part between the two engines. Loading air, oil and water cooler, clutch and a second petrol pump, everything exits twice. Air not needed is lead back to the aerodynamic formed parts below the body and should especially at high speed improve the drive at the rear and it is supported by a diffuser. A marked carbon lip at the mtm tail wing supports this effect, too.

By the standard rear window, similar to a Ferrari 360 Modena, it is possible, even desired, to look at the technology of the second drive unit. According to Roland Mayer the plastic covers only use is not to have tc tidy up electronic cables and lines. This expenditure is operated by mtm because the customer should be able to look at the technology of the bimoto.

The customer will feel the technology, that’s already sure. The project double engine vehicle is remarkable but for a firm with the entitlement of mtm not sufficient. Both engines will be far away concerning th performance output compared to the series. Unwaveringly and also everyday life-suited 740 HP, thus 370 H for each engine, are the minimum. Even 501 HP per four-cylinder are possible, which will be reached by capacity enlargement to 2 litres, big turboloaders and working on the periphery, says Mayer full of proud Finally however the customer should have the choice to decide on performance variant respectively deployment purpose of the vehicle.

The target is to give the car a handling, which is any time calculable. It may not surprise the driver with a change between under- and overriding but has to show the tendency to override. In Wettstetten we use therefore the standard sensors for the ABS system. The monitoring of the number of revolutions at all four wheels allows, by the help of the engine-electronic, an exact invasion to the handling of the bimoto. For example with slip at the front axle performance will be taken back from the front four-cylinder to avoid under riding. Similarly to that traction problems and power influences of the driven front axle to the steering will be avoided.

Behind the front, forged 19M-light metal rim a Brembo braking system is installed. Ventilated disc brakes, 32 millimeters strong and 355 millimeters in the diameter are taken there by a four-piston caliper into the pliers. At the rear axle acceleration will be converted to delay with ventilated, 330 millimeters big brake discs and a four-piston caliper.

With six-point-belts in Recaro full-bucket seats in future maximally two passengers have the possibility to feel the experience double engine in the exclusive MTM bimoto.

The development costs for the prototype are about 600.000 euro, A small series of 10 vehicles is planned. Optionally also a race-suspension and/or race-suspension-parts can be ordered.
