Audi unveiled the new 2017 Audi S4 sedan and S4 Avant at the 2015 Frankfurt Motor Show. The most important change in the new S4 is the adoption of turbocharging technology in place of the current model’s supercharger.
The heart of the 2017 Audi S4 models is a newly developed V6 engine with gas direct injection and turbocharging. The 3.0 TFSI has an output of 354 hp and 368.8 lb-ft of torque is available from 1,300 to 4,500 rpm.
Its extra torque from the turbo engine is the reason why Audi is switching from the current model’s seven-speed dual-clutch transmission to an eight-speed, torque-converter automatic. Its eight speed tiptronic transmission can sprint from 0 to 100 km/h in just 4.7 seconds (0.2 seconds faster than the current model) and the top speed is electronically limited to 250 km/h.
