B9 A4 (2017-present)


The B9 chassis is an evolutionary change from the B8 rather than a revolutionary one. The B9 grew a bit in size but sheds some weight due to lightweight construction. The powertrain is the most significant change with the new engine coming with 248 HP / 273 TQ from Audi, with an APR tune this increases by a staggering amount to 306 HP / 376 TQ!
