I'd love to be proved wrong, but too many years studying mpg figures teaches me to be a little cautious of such a jump in the official combined figure. I expect a bigger percentage of mpg shortfall, than the previous generation.
My 640DM Sport with 6 speed auto gave 38MPG, this 35D M Sport x3 gives 37MPG, the new 3 series Touring is 255Kg lighter and so should be cheaper to run with a low drag coefficient , the F30 M Sport has also been lowered suspension wise so that may help.
