The Car to Beat in 2007

A new design distinguishes the further developed Audi R10 TDI from its successful predecessor that started its winning streak exactly one year ago and remains unbeaten since then. To ensure that it remains the car to beat in 2007, innumerable details were optimized on the LM P1 Prototype.
The R10 TDI carbon-fibre monocoque is identical to last year’s design. Minor aerodynamic modifications, which are only visible to the trained eye, were made to the exterior surfaces.

The friction and weight levels of the entire powertrain were reduced. The two diesel particle filters are also now smaller and lighter. Tire partner Michelin supplied new compounds and constructions to improve the balance between front and rear axles. The R10 TDI suspension and dampers were also refined.

Audi improves upon the R8

At first glance, it is visible that the new Audi R10 TDI carries genes from the extremely successful R8. Nevertheless, the LM P1 sportscar’s chassis is a new design, during which Audi Sport explored many new avenues. “The R8 originates from 1999, we’ve gathered a huge amount of know-how since then,” says Wolfgang Appel, Head of Vehicle Technology at Audi Sport. “All this experience found its way into the new R10 TDI.”

Innovative details

Audi’s target with the sports-prototype – currently the world’s most interesting motorsport category – is to set the standards once again and to highlight the company slogan “Vorsprung durch Technik”. Numerous innovative details and new design principles were used in the Audi R10 TDI.

One of the most significant differences to its predecessor, the R8, is the integration of monocoque and bodywork. The R8 still had a traditional chassis clothed in synthetic bodywork, whereas the majority of the carbon-fibre parts belonging to the R10 TDI monocoque are now suspended directly in the air flow and therefore require no additional fairings.

Increased comfort

Although the R10 TDI prototype’s carbon-fibre monocoque is more waisted than that of the R8, the drivers can sit comfortably in the cockpit – a factor not to be underestimated in a 24-hour race like at Le Mans. The servo steering, which is now electric instead of hydraulic, also helps to increase comfort.
