BMW i8 coupe

The BMW i8 coupe is certainly the most radical looking car on this list. It is built from lightweight aluminium and carbon fibre, yet that s not the reason it looks so striking. It s been designed to slip through the air as efficiently as possible to extract every last mile per gallon.

That s particularly important, because under the skin sits a 1.5 litre petrol engine and two electric motors. Even though it s capable of getting from 0 62mph in just 4.4 seconds, it can still return 135mpg and its CO2 emissions of 49g/km means that not only is road tax free, but it s exempt from the London Congestion Charge too.
