Driving the 320d even for half a day reveals why this is the top pick in the range and it’s all down to a great mix of power and frugality, torque and efficiency, fun and responsibility. The fact that the engine has a twin-scroll turbo helps out a lot, as all the torque it can deliver comes on pretty quick. Push it a bit harder and the torque replies by creating a perfect replica of the seatback on your backside. Don’t get me wrong, I know 400 Nm of torque is not an incredible figure by today’s standards but it is enough on a car of this size.
