I am a little surprised by the "B" pillar but I like the idea since it will make the frame stiffer for road performance which is my preference.
I think it detracts from the look/lines of the car. I'd rather see it removed. I think a 2-door should be a
hardtop, not a
coupe. The back seats will be WAY too claustrophobic without an operable rear window, not to mention that the concept is "
sans B-pillar".
