Audi, the inventor of TDI, is preparing to launch a diesel offensive in the North American market. The brand with the four rings will introduce the world’s cleanest diesel to the U.S. market in early 2009, almost simultaneous with its introduction in Europe. The 3.0 TDI with its ultra low emission system, which fulfills the world’s most stringent emission standards, will first be offered in the Audi Q7 and then in the new Audi A4 at a later date.
The ultra low emission system ensures that the engine conforms with the limits included in the LEV II Bin 5 standards that apply in all 50 U.S. states. Engine features optimize the combustion process along with engine emissions, while a cleaning system reduces nitrogen oxide exhaust emissions by up to 90%.
The V12 TDI unleashes the kind of incredible power that also makes it a suitable engine for a supercar – Audi unveiled a concept car based on the R8 at the Detroit Auto show earlier this year. Again – in a mid engine configuration – the engine produces a whopping 500 hp and 737 lb/ft of torque, which is reached at only 1,750 rpm. In terms of design, the Audi R8 V12 TDI is reminiscent of the Audi R10, the two time winner of the Le Mans 24 hour race, and the engines are also close relatives.
