Despite a sharper focus on comfort, BMW's latest 5 Series saloon is still a sporty choice - and winner of our 2013 CarBuyer Best Large Executive Car award. And although it looks plainer, the car is more desirable than ever. All cars get EfficientDynamics equipment – on the 520d this includes stop-start that cuts the engine in queuing traffic to save fuel. All this ensures the 5 is green as well as fun to drive. Top seller is the 181bhp 520d, with 56.5mpg or 62.8mpg in recently introduced EfficientDynamics (ED) trim. There are SE or M Sport trims; the latter has more racy looks and firmer suspension.
