BMW EfficientDynamics isn’t a mere categorical name to impress the economy craving consumers and it does manage to attain a very high fuel economy with very low emission numbers as reported by famous UK motoring journo Tom Ford.
Tom drove a 320d on a full tank from UK to Munich and back and he managed to travel a whopping 1013 miles. Calculate those numbers a little better and you get 68.9 mpg and do not miss out on the fact that Tom also reported CO2 emissions of only 109g/km. Tom did drive carefully but he mentioned that he wasn’t conscious of the economy run factor and there were times when he even bagged 75.9mpg. He was thoroughly impressed by the 320d as he mentioned that the dubbing EfficientDynamics isn’t merely efficient by its name, only.
