Sure you may average 24mpg in your 135, but how much of that is highway driving? I used to average 35 when my commute was 75% highway, but that's hardly a fair representation of "combined" mpg.
The math may be a bit off because the number I used for comparison, the 27 mpg combined figure for the US 335d, is demonstrably low. In 50-50 mixed driving it's actually closer to 30-31 mpg. Even using 31 in the proportion, the estimated efficiency for the 4 cylinder is 25.7. Not exactly ground breaking.
