> Design - The M4 stands out from the regular 4 - series with a «powerdome» bonnet,
swollen wheelarches, deep air intakes and, the now obligatory for an M - car, quad - tailpipes.
The Coupé's second heartline, also shared with the Convertible, begins at the rear edge of the door,
swelling outwards and upwards to create a visually strong
wheelarch, emphasising the car's rear - wheel drive layout, before dropping vertically through the tail lamp.
