BMW 4 Series Coupe review

The BMW 4 Series is a relatively modern invention, but it’s essentially the current name for the old 3 Series Coupe. The mechanical underpinnings, interior and engines are all shared with the more conventional executive saloon, but that’s no bad thing, because the 3 Series is utterly, utterly brilliant. Add in a more striking grille and a sleeker body, and you’ve got a truly awesome coupe that’s at home absolutely everywhere.
