• 2013 BMW Gran Coupe 650i to receive revised N63 twin turbo V8 with 450 horsepower, 50 more than standard N63/650i

      The BMW 6 series Gran Coupe 650i will have 450 horsepower and 479 pound-feet of torque. This is 50 more horses than the standard 650i coupe. The N63 V8 was revised for duty in the heavier Gran Coupe but we do not know what changes were made. It will be interesting to see if it is software only or if there are hardware changes which no doubt many 650i, 550i, X5 xDrive50i, and X6 xDrive50i owners will be interested in retrofitting.

        More boost makes sense, source on valvetronic?

        There it is, valvetronic and more boost it is. I was hoping for bigger turbos, oh well.

        That picture tells me the N63 owners have a harder time than most to change sparkplugs, what's up with the bend just before the plug, must be a pita to get to.

        BMW is going to over-price the hell out of this car. It will be comical.

        The 6 series is pretty damn overpriced to begin with.

        Is this picture supposed to be of the N63? I think this is the S63.

        Well then it's using a different exhaust manifold from what is on older N63's this has the S63 manifold.
