The design of the car does not differ much from what we all expect but the classic aggressive M3 fenders are there thankfully. A more aggressive front bumper along with rear diffuser sporting quad tips round out the look. Overall, BMW is playing it very safe styling wise.
Reflections in the window make it difficult to see much of the interior although a dual clutch trans can clearly be made out along with tri-color M stitching on the wheel. Photographer stated redline was 7k rpm. So much for that high revving M philosophy eh?
The shot underneath the car shows what appears to a fairly large tranny cooler (hopefully not sharing the same cooler as the manual as BMW did with the E9X generation) as well as a big and likely heavy rear muffler that aftermarket exhaust manufacturers will be promptly ditching.
Great set of spyphotos and a big thank you to BimmerBoost member @bmw335iguy for capturing the car.
