Audi revealed full details on the 2009 Q7 V12 TDI quattro: the world’s most powerful diesel-engined SUV. The SUV is priced at 130,600 Euros (although no U.S. pricing has been announced, the current exchange rate puts the price at about $184,000.) Ouch!

With a completely redeveloped common rail injection system the twelve-cylinder delivers a mighty 368 kW (500 hp) and 1,000 Nm (737.56 lb-ft) of torque from a capacity of six liters – giving the big SUV the performance of a sports car.

In everyday use the twelve-cylinder diesel is relatively frugal with economy of 11.3 liters of fuel per 100 km (20.82 US mpg). On demand, the six-liter engine catapults the Audi Q7 from zero to 100 km/h (62.14 mph) in 5.5 seconds like a top-class sports car. Speed is electronically capped at 250 km/h (155.34 mph).

The world’s most powerful diesel-engined SUV will make its way to dealers towards the end of 2008.
