I doubt diesel engines will be able to rev as high as the current gasoline powered engines... but if diesel were to make it into F1, we might actually get to see an F1 car with Torque!
Engine
The main novelty of the R10 is its engine: a TDI turbodiesel engine, running on Shell V-Power Diesel. It is a 5.5 L (335.6 ci) all-aluminium bi-turbo 90° V12, with common rail direct injection of more than 1600 bar (23,206 psi). Its output should be 650 hp (485 kW) (regulated) and 1100 N·m (811 ft·lbf) of torque, and its usable power band is between 3000 and 5000 rpm. Its benefits are a broad range of usable power, high torque and economy. Two Garrett TR3076R turbochargers limited by the regulations to 2.94 bar (42.64 psi) absolute breathe through two 39.9 mm intake air restrictors. It uses the latest Bosch Motronic (MS14) management, provided by Bosch Motorsport, 1600 bar piezo injectors, and makes a low noise for a race car.
It will be difficult for Audi to overcome the weight of this engine. The latest Audi TDI 3.0 L V6 (183 ci) weighs 220 kg (485 lb) and the 4.2 L V8 255 kg (256.2 ci, 562 lb) but their blocks are made of CGI iron. The V12 is rumoured to weigh upwards of 200 kg,[4] Audi engineers admit that the weight per cylinder is the same as the precededing 3.6-litre FSI V8 of the Audi R8.[5] The wheelbase has been increased over the R8 to 2980 mm to account for this. This is unfavorable against the 130 kg (287 lb) of a concurrent Judd V10, and even the 180 kg of the Ricardo turbodiesel prototype based on it.[6]
Audi's decision to use a diesel engine emphasizes the commercial success of TDI (and its competitors) on Europe's roads. It isn't however, the first diesel to be raced at Le Mans. In 2004 a Lola equipped with a Caterpillar re-badged VW V10 TDI ran for a few hours before breaking its gearbox. The first diesel-engined car to qualify and race at the 24 h race at Le Mans was a French entry in 1949, the first race held after the war. The car was the Delettrez Diesel entered by brothers Jean and Jacques Delettrez and was a 4395 cc 6-cylinder. It did not finish, running out of fuel about half way into the race. Delettrez entered again in 1950, as did another diesel car, the MAP. Again both cars DNF with engine problems, a cooling system leak in the case of the MAP. The MAP was interesting in that it was the first mid-engined car to race at Le Mans, the engine was located immediately behind the driver, and was a two-cylinder opposed piston two-stroke with rocking levers connected to a single crank, similar to the later Commer TS3 engine. Peugeot will compete with its new diesel effort in 2007 in its 908 race car.
