Super FAST Autobahn ACCELERATION and SOUND shootout between the recently facelifted 2015 / 2016 Mercedes-AMG A45 (2.0 R4, 381hp, 475Nm) and the new Audi RS3 (2.5 R5, 367hp, 465Nm). As I drove both of these powerful compacts in the past month it was time to put them head-to-head and compare how they accelerate and sound in real-life. While the A45 has raw and lound sound which includes raw pops & crackles the RS3 is more hollow-sounding and creates an addicting noise like a V10. In this particular shootout the RS3 has the optional “Sports Exhaust” and the A45 the optional “performance exhaust”, both with active valves (Klappenauspuff) Inside the cabin the 4-Cylinder AMG is alot more present as they let engine noise come in, the RS3 somehow gives the more relaxed character and under normaler conditions its slightly quieter. Once the RS3 opens its flaps (dynamic mode) it is phenomenal what they have squeezed our of a quite small engine. Once BMW M2 and Focus RS are available for a drive I will of course also try to capture shots! If you enjoy watching clips like this please don’t hesitate to LIKE / COMMENT / SUBSCRIBE!
