Audi has introduced the SQ5 TDI—the brand’s first S model with a diesel engine. The biturbo SQ5 TDI accelerates from 0 to 100 km/h (62 mph) in 5.1 seconds, with an average fuel consumption of 7.2 liters per 100 km (33 mpg US).

Boosted by two turbochargers, its 3.0 TDI produces 230 kW (313 hp) and 650 N·m (479 lb-ft) of torque between 1,450 and 2,800 rpm. The Audi SQ5 TDI will be in dealerships in the first quarter of 2013.
The 2,967 cc TDI uses a twin-turbo design in which the two turbochargers are connected in series via a flap. Cylinder head cooling, the timing and lift of the intake cam shafts, the pistons, their oil-jet cooling and the piston pins have been specially designed for the high-performance concept. The common rail system develops as much as 2,000 bar of pressure and injects as many as eight shots of fuel into the cylinders per cycle.
Innovative thermal management, a start-stop system and the regulated oil pump all contribute to the fuel economy. A fast and smooth-shifting eight-speed tiptronic and quattro permanent all-wheel drive with torque vectoring transfer power to the road.
