The BMW M3’s top competitor is undoubtedly the Audi RS5. Powered by the S65B40 engine, a naturally aspirated, high revving 4-liter V8 capable of 414 horsepower at 8,300 rpm and peak torque of 400 Nm at 3,900 rpm, the BMW M3 is a crowd favorite.
The Audi RS5 however has a 4.2-liter V-8 that makes 450 hp at 8250 rpm – 30 horsepower more than what the BMW M3 can produce. But is this enough to beat the BMW M3 on the road? AutoExpress thinks not.
According to this review, nothing beats the BMW M3. In fact, they suggest it as a therapy for those who are depressed. In their own words, “this car can be a lunatic!”
