I was just point out the significant weight difference. I wonder what kind of figures the S65 could've generated if someone lopped off 15% of the chassis's weight.

My 2006 GTO with a 6.0 LS2, 6 spd and a small cam plus full exhaust (roughly 380 rwhp from the stock 330rwhp mine put down) could get 27 mpg easily while my stock 2012 135i 6 spd can only get 25 mpg.
GTO was around 1800 RPM at 68 while the 135i is somewhere around 2200 RPM at the same speed.

Absolutely, gearing will yield great results, which is why it looks like the 7MT in the C7 features the exact same first six speeds as the C6's 6MT plus a giant overdrive gear for seventh.
