INGOLSTADT, Germany — After showing a diesel concept of its R8 supercar in Detroit, Audi is bringing diesel to the sports-car market with the TT 2.0 TDI. Audi claims to have the first diesel sports car with its unique package that combines the TT's iconic sloping roof line and respected handling with a fuel-sipping engine.
Due to the engine's torque output, all diesel TTs will come equipped with Audi's Quattro four-wheel-drive system. In normal operation, it sends 85 percent of the power to the front wheels, but is capable of diverting all power to either the front or the rear axle. Sales of the TT 2.0 TDI are currently only planned for Europe.
