MPG = 29.4?
The 135 coup highway MPG is listed at 28. I figured more HP and Torque, wider tires, fancier body work (less smooth), and a wider car would all add up to worse highway MPG.
Turns out it's pretty widely reported (but not official that I could find) that the 1m highway is 29.4 MPG. Can anyone confirm this number? I googled for "1m 29.4 mpg", 2nd hit was 1addicts.
I guess the fancy "air curtains" have a rather noticeable effect. Kudos to BMW.
Maybe we need a new metric that combines highway MPG and Nordschleife lap time. My best guess is that none of the cars anywhere near the 1m have better MPG. Gotta work it out so 60 mpg car that takes 15 minutes doesn't win though.
Another pleasant surprise that during the overboost you get 369 lb-ft starting at 1500 RPM. The M3 peaks at 295 lb-ft. Seems like combining less weight (400 lbs) and more torque (369) should make the 1m less sensitive to RPM.

From the BMW official specs:
urban (l/100km) 13.6
extra-urban (l/100km) 7.3
Total (l/100km) 9.6
.136 liter/km = 17.3 miles per US gallon (20.8 miles per Imperial Gal)
.073 liter/km = 32.2 miles per US gallon (38.9 miles per Imperial Gal)
.096 liter/km = 24.5 miles per US gallon (29.4 miles per Imperial Gal)
Highway mileage seems a little unrealistic to me. Unless the side air curtains REALLY are just that good.

Personally don't know of any 135i owners achieving under 10ltrs/100km with varied driving conditions...more like anywhere from 13-16ltrs/100km.
Are aerodynamic improvements on the 1M going to lower it that much, considering the 1M will have a higher fuel burn tune than a 135i ??
I think one could probably achieve those numbers without prodding the loud pedal too much...
