Audi Q7 V12 TDI

From Audi press: Audi has stood at the forefront of diesel technology for the last three decades. The Ingolstadt brand now presents a further world first – the first V12 diesel engine in a passenger car. The new Audi Q7 V12 TDI is powered by a twelve-cylinder diesel engine containing a wealth of pioneering technology. With an outstanding 500 PS and 1,000 Nm of torque, the six-litre engine of the high-performance SUV provides the driving performance of a sports car.

Sprinting from 0 to 100 km/h in just 5.5 seconds and achieving an electronically governed top speed of 250 km/h, the Audi Q7 V12 TDI is catapulted into the echelons of top-class sports cars. New horizons have been set in the diesel market thanks to this outstanding power. None of our competitors can offer a comparable engine.

The big performance SUV from Audi accelerates with impressive ease. Superior power reserves in any situation are provided by the world’s first 2,000 bar Bosch Common Rail system. The ultra-modern piezo-injection system offers impressive acoustics at the highest levels of driving comfort.

The new six-speed tiptronic gearbox, which features extensive reinforcements, shifts quickly and comfortably. It transfers the enormous power to the quattro permanent four-wheel drive system. The new Audi Q7 V12 TDI has an average fuel consumption of just 11.9 litres per 100 kilometres.

All diesel engines from Audi are highly dynamic thanks to their high performance and high torque characteristics. Audi has often proved its sporty character in series production, most recently through the six and eight-cylinder 3.0 TDI and 4.2 TDI engines. Audi also rewrote the record books earlier this year on the racetrack. Following its debut in Sebring, Florida, the premium R10 prototype sports car won every long-distance race it entered.

These included the Le Mans 24 Hours road race, probably the most difficult race in the world for both man and machine.

The V12 race engine in the R10 squeezed 650 bhp from its 5.5-litre engine capacity, reaching a top speed of 330 km/h. The power and endurance of the R10 was an immediate hit with fans and experts alike. However, what completely surprised them was the sound of the engine: unlike most racing engines, the powerful Audi diesel engine runs whisper-quiet.

Like most Audi V-engines, the maintenance-free chain drive is located on the back of the engine in a space-saving arrangement. A new layout is used in the new V12 TDI. The chain wheel of the crankshaft locks into the gearwheel. From here two simplex chains drive the camshaft. Two further chains drive the oil pump and both high-pressure pumps in the common rail injection system.

The Audi Q7 V12 TDI is impressive not only with regard to technology but also in terms of appearance. The most striking visual changes to the Audi Q7 are the underbody panels at the front and rear. The chrome-plated single-frame radiator grille evokes the tradition of the Audi S6 and S8. These two cars, with their

V10 FSI engines, are the top sports models in their class. The V12 TDI features a powerful braking system which is every bit its equal.
