September 15, 2006 Audi is set to debut the first twelve-cylinder diesel engine in a series passenger car. A six-litre V12 will be available in the Audi Q7 that is reminiscent of the engine featured in the all-conquering R10 Le Mans racing car and it catapults the driving performance of the Audi Q7 SUV into the echelons of top-class sports cars. The V12 TDI engine produces a colossal 500 PS and 1,000 Nm of torque giving the car a 0 to 100 km/h time of just 5.5 seconds, and 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 world’s 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.
