The diesel Audi R8 V12 TDI 500hp engine should drop four tenths of a second off the 0-60 time to bring it down to 4.2 seconds. Fuel consumption will be brought down from the gas model’s from 16mpg to 23.5mpg. The diesel motor in Audi’s R10 LeMans racecar revolutionized the race by needing less fuel and providing more than enough power. It’s just leaked onto the web that Audi could be bringing a V12 turbodiesel Audi R8 V12 TDI to Detroit’s NAIAS this month. The Audi R8 V12 TDI is labeled a concept, but rumor has it that production is already planned. Given the leaks and new-car debuts we’ve already seen, diesels may be the story of the Detroit show like plug-in hybrids were the story in Frankfurt. More efficient and more powerful is an odd combination, but one made possible by diesel power. The R8 V12 TDI powerplant Audi has shoehorned into the Audi R8 V12 TDI will produce 500bhp and 738ft/lbs of torque. Compared to the already very respectable 420hp provided by the gas motor in the standard Audi R8, the new motor - sourced from the Audi Q7 - is even more monstrous. In a particularly prescient moment, we predicted this very occurrence over a year ago. By putting a tiny Audi R8 under the Audi V12 TDI motor instead of the rather gargantuan Q7, Audi should be able to eek something like 28mpg out of the combination. For those thinking the R8 TDI just might be the perfect car, there is one, rather huge, drawback: there is reportedly no luggage space. The longer and larger V12 engine extends into the room reserved for luggage in the Audi R8’s rear compartment, near the engine. However, something others have missed is the luggage space up front, which is adequate for a solid weekend’s worth of clothing for two - which puts the R8 V12 TDI right back in the running for the ultimate weekend tourer.
