About the Audi S4 B9
The B9-generation Audi S4 underwent a significant shift for the European market in 2019, replacing its petrol V6 with a 3.0-litre TDI diesel engine. This unit features a 48-volt mild-hybrid system and an electrically powered compressor (EPC) to virtually eliminate turbo lag, delivering a massive 700 Nm of torque. While the change was controversial among enthusiasts, it transformed the S4 Avant into a formidable long-distance cruiser with effortless overtaking ability and improved fuel efficiency. The Avant body style remains the quintessential choice for this model, offering 505 litres of luggage space and Audi's signature high-quality interior finish.
