3,700 lbs!! That’s the lightest M based performance vehicle that BMW currently makes. It used to be that if you wanted a true no-holds-barred sports sedan, then these were the guys you went to. However these days it seems that BMW is more concerned with volume than actually producing a true car for the enthusiast. In fact the last car we saw that really pushed all the right buttons was the 1 Series M, but of course they killed it off after building just 6,000 of them. Why would you do that? According to Motor Trend’s Jonny Lieberman, there still may be hope for the brand as he recently got his hands on a 2014 M6 Gran Coupe. Yes it’s big and expensive, but according to him, it’s one damn fine automobile. Check it out after the jump.
