A quick dub over to see what the new E Coupe might have looked like without the small 3/4 window. All I did was move the door cut line back a few inches.
I chose this mule because I like the pumped up hood line, another nice feature missing on the production car and on any other Mercedes-Benz coupe. A belt line would have added some sculpture
to the body. Rear windows also slightly shortened so as to not interfere with the fuel filler cap. (the designers could have moved the cap back an inch or two like on the S to accommodate the rear window glide. The slight kick in the B pillar keeps the design in check and adds flair I think. The vents on the side might have been another distinctive feature for the E coupe in the lineup but would this have been enough for new E to stand out from the pack.
