This is stunning. I usually detest BMWs (with the i8 as an exception), but this really has potential. Excellent proportions and detailing. I have very very little confidence in BMW to not screw it up come the production model. Those tail lights will be stream-lined into a generic 3-series blob. No way those big intakes and squinty lights will stay. Also not sure about that deep body crease.
I'm hoping they prove me wrong because the i8 proves BMW can be daring and interesting. Considering this is an entirely new model range (or at least a return of an old nameplate), they can afford to be daring no? (>looks at milk toast boring 4 series...)
It's more fun to drive a slow car fast than a fast car slow.
