While we were playing with Audi's smaller V8-powered diesel Q7 (thanks to the folks at Honeywell), it looks like the multi-ringed brand was working on taking the rocket-powered powerhouse of an SUV to a whole new oil-burning level with the new Audi Q7 V12 TDI. With the new bigger, longer and more uncut diesel engine under the hood it officially makes the new Q7 the most powerful diesel-powered passenger vehicle around. That big 6.0-liter engine generates a whopping 500 HP and (wait for it) an astonishing 757.5 lb-ft of torque. That means the new Q7 has a 0 to 100 km/h (62.14 mph) time of just 5.5 seconds. On average, it requires just 11.9 liters of fuel per 100 km — a figure translating to roughly 19.77 MPG. Do want. Oh yes, definitely do want. Presales of the Audi Q7 V12 TDI will begin in Germany during the second half of 2008 and we're of the assumption people will be calling it a 2009 model. Full details below the jump.
