( Motor Authority )- Audi has shoehorned its mighty V12 TDI engine into the Q7 to create the most powerful diesel-powered passenger vehicle in the fullsize SUV class. The monster mill under the hood generates 500hp (368kW) and 1,000Nm (757.56 lb-ft) of torque from its 6.0L of displacement and makes this one of the quickest SUVs on the planet.
On demand, the V12 engine catapults the Audi Q7 from 0-100km/h (62mph) in 5.5 seconds and effortlessly takes up to its electronically controlled top speed of 250km/h (155mph). Despite the impressive performance numbers, on average, the new model requires just 11.9L of diesel per 100 km (20mpg).
The car also rides on an aluminum chassis with a double wishbone suspension set-up up front and Audi's adaptive air suspension and electronically controlled shock absorbers with dynamic roll stabilization. The V12 Q7 also gets optional 21in wheels housing standard 20in carbon-ceramic brake discs. The front disks are gripped by eight-piston brake calipers, while the rear brakes function with four pistons each.
Inside, passengers are treated with aluminum inserts and velours carpet, carbon and aluminum trim and stainless steel pedals. Verano leather covers the electrically adjustable sport seats, the center armrest and the door inserts. The front and rear seats can be heated, while a special lighting package provides ambient mood lighting.
Complementing the engine transplant is a sportier chassis, custom bodykit and more extensive standard equipment list. Production of the new model will be handled by Audi's quattro subsidiary and the first cars will roll onto showroom floors by the middle of the year.
