Bmw should take inspiration on this awesome M4 render
It is huge? Wider rear and front is better on track, but it need to be lot of ligher than E9X, just make it weigth under 1600kg. Basic 335 F30 weigth is 1600kg? And it´s wear steel parts on chassis, so maybe 1500kg is possible and less weigth = better fuel economy and better driving excperience, win to win situation.
