The BMW 4 Series is great to drive, smart inside and roomier than you might imagine. With its powerful engine, the M440i is great fun, but the 420i strikes the best balance between performance and running costs while still impressing on a twisty road.
A 3.0-litre six-cylinder petrol engine that pumps out 369bhp, which is fed to all four wheels via an eight-speed automatic gearbox. If you’re thinking that sounds like a recipe for some explosive acceleration, you’d be right. Indeed, the M440i can hit 62mph from a standstill in just 4.5sec.
