In conjunction with the 24 Hours of Le Mans, Audi is presenting the new top model of its recently revised Q5 model series – the Audi SQ5 TDI.
Boosted by two turbochargers, its 3.0 TDI produces a brawny 230 kW (313 hp) and 650 Nm (479.42 lb-ft) of torque between 1,450 and 2,800 rpm. The Audi SQ5 TDI will roll into dealerships in the first quarter of 2013 and is the first S model in the history of Audi with a diesel engine.
The powerful TDI, which displaces 2,967 cc, 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. The 3.0 TDI biturbo has a great sound. This sound is further modulated by a sound actuator in the exhaust system – a loudspeaker in short side channel.
