Filed under: Crossovers, Audi Q7, SUVs, Luxury
INGOLSTADT, Germany - Audi is proud to present a world first – the first twelve-cylinder diesel engine in a series passenger car. This six-liter V12 makes its debut in the Audi Q7. It produces a colossal 500 hp and 738 ft.-lbs. 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 62 mph in just 5.5 seconds, and has an electronically governed top speed of 155 mph. Maximum torque is available from just 1,750 rpm. The high-tech diesel engine, with the world’s first 29,000 psi 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 29,000 psi 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 nearly 20 mpg. With the high-tech twelve-cylinder engine using TDI technology, the diesel pioneers at Audi have opened new horizons in motoring.
