Q7 V12 Tdi
Audi is proud to present a world first the first twelve-cylinder diesel engine in a series passenger car. This six-litre V12 makes its debut in the Audi Q7. It produces a colossal 500 PS and 1,000 Nm of torque. With this engine Audi has opened a new chapter in diesel history.
The V12 TDI is reminiscent of the engine featured in the new R10 Le Mans racing car it catapults the driving performance of the Audi Q7 into the echelons of top-class sports cars. The car sprints from 0 to 100 km/h in just 5.5 seconds, and has an electronically governed top speed of 250 km/h. Maximum torque is available from just 1,750 rpm. The high-tech diesel engine, with the worlds first 2,000 bar Bosch Common Rail system, provides the high-performance Audi SUV with superior power reserves in any situation. The impressive sound of the new Audi is provided by the ultra-modern piezo-injection system. The V12 TDI transmits this power through a new six-speed tiptronic gearbox to the quattro permanent four-wheel drive system.
Although the V12 TDI belongs to the Audi V-engine family, this model features a special cylinder angle of 60° perfect for this engine type. Apart from the light and highly durable crankcase, a further highlight is the new chain drive assembly. This includes the two newly developed high-pressure pumps in the common rail injection system.
Up to 2,000 bar of pressure is kept within the twelve piezo injectors a further technological breakthrough. Both performance and efficiency are optimised by this high injection pressure, and the running smoothness also remains excellent. Exhaust emissions are also low. The twin-turbo V12 TDI conforms to the Euro 5 emissions class which should come into force in 2010. Fuel consumption is only 11.9 litres per 100 kilometres. With the high-tech twelve-cylinder engine using TDI technology, the diesel pioneers at Audi have opened new horizons in motoring.
500PS, 1000Nm between 1,750 - 3000 rpm, 0-100km/h in 5.5s
