The heart of the S models is a newly developed V6 engine with petrol direct injection and turbocharging. The 3.0 TFSI has an output of 260 kW (354 hp); its 500 Nm (368.8 lb‑ft) of torque is available across a wide range of speeds from 1,300 to 4,500 rpm. The engine outstrips its predecessor in terms of power and torque, while simultaneously offering significantly lower fuel consumption and weight. The engine can accelerate the Audi S4 from 0 to 100 km/h (0 to 62 mph) in 4.7 seconds, and the electronic limiter kicks in at 250 km/h (155.3 mph). Despite its considerably improved performance, the V6 is extremely efficient. In the NEDC cycle, the S4 Sedan consumes less than 7.4 liters of fuel per 100 kilometers with 170 grams CO2 per kilometer (31.8 US mpg [273.6 g/mi]).
