We’ve kept the 320d Efficient Dynamics pretty much exclusively in Eco Pro mode to maximise efficiency because, unlike some cars, it doesn’t have much of an impact on the driving enjoyment. However, the little symbols that pop up on the dash are becoming irritating. Whether it’s to say slow down to optimise efficiency, or don’t push the accelerator so hard, it’s like driving with your mother-in-law in the car.

Better is the bonus range indicator. It shows the effectiveness of efforts to drive efficiently by giving an ‘extra mileage’ figure achieved with each tank.
