January 16, 2008 Audi looks set to create a new class of road-going supercar following the first showing of its R8 TDI Concept at NAIAS this week. Using the V12 6.0-liter bi-turbo TDI engine first seen in the forthcoming Q7 V12 TDI SUV, the 6.0-litre twin-turbo V12 with 500 bhp is similar in basic concept to the R10 TDI’s 5.5-litre race engine, and delivers – wait for it - 1,000Nm of torque - between 1,750rpm and 3000 rpm, guaranteeing the effortless delivery of a 4.2-second 0-62mph acceleration time and a top speed in excess of 186mph. The 4WD beauty has a full set of goodies, such as Audi’s magnetic adaptive suspenders, it already meets the proposed EU6 emission limits expected to apply from 2014 and comes with a GPS system that incorporates race circuit information and centrifugal force / boost pressure data when the car is in race mode. Hey guys, you’ve gotta make this one!
