If this needs to be communicated briefly, via Twitter or somesuch, just tell them it’s the best car in its class. Still. Because it is. If you want to go into much depth, begin with increased dimensions (93mm longer, 9mm taller etc) and go on to discuss how the new lower nose design has improved both aerodynamics (0.26Cd for the most air-cheating models) and pedestrian safety.
Of course it’s not a revolutionary leap forward. This is a mainstream car that sells in massive numbers - when it goes on sale in the UK next February it needs to appeal to as wide an audience as possible. We can’t see it alienating many. With the exception of the pointier front end the exterior is entirely fine. Nothing radical, just a good freshen up. Same indoors, too. BMW has been bolder with materials, folding them into more interesting shapes, yet the ergonomics are excellent and the quality and design is fully up to scratch.
