2017 BMW M4 Convertible Engine

9.6/10

“The M4 drives a lot like a sports car. It accelerates with potency, turns sharply and stops quickly. There’s little reason to crave more performance, though the steering doesn’t communicate much road feel to the driver. Still, this is a car that does an impressive number of things very well.” – Edmunds

9.2/10

“The M4 coupe and convertible look similar to those of the 4 Series, but their unique traits are easy to see if you know where to look. The hood features a power dome that you can think of as a bicep signaling this performance car’s extra muscle. Around back are quad exhaust outlets.” - Kelley Blue Book
