Yup, I knew there was no way in hell a heavier AWD X1 was going to get 33 when the lighter, slipperier RWD F30 gets the same after the revision. 30 sounds about right in ideal conditions, 31 with a slight tailwind. This is why for now I'm sold on the 35i although I'd prefer the big numbers the 20d will no doubt put up and likely beat real world.
