An important component of the B-cycle combustion process is the central position of the injectors in the combustion chamber. In the area around the inlet valve, this makes possible a geometry which, in interaction with the inlet ports, allows for targeted mixing up of the gas charge. The common-rail system injects the fuel into the combustion chamber with 250 bar of pressure - the high injection pressure ensures a homogeneous spray pattern and consequently a uniform propagation of the flame front.
The bi-turbo‘s power flows through a sportily-tuned, eight-speed tiptronic transmission with optimized shift times and on to the quattro permanent all-wheel drive which features a self-locking central differential. The drive forces are asymmetrically distributed between the axles in the ratio of 40:60. Dynamic handling with optimum traction and the best-possible levels of safety are thus guaranteed. Audi Sport also offers an optional rear sport differential.
The high-output V6 doesn’t just impress with its strong performance, but also with its high level of efficiency. In the NEDC, it consumes just 8.7 liters of fuel per 100 kilometers (27.0 US mpg), which corresponds to 197 grams CO2 per kilometer (317.0 g/mi). This means a 17 percent consumption saving compared with the previous model. A decisive factor in this is the new TFSI combustion process from Audi, which is known as the B-cycle. It has been specifically designed for the partial-load range, which is the predominant operating mode during normal use.
