...or for that matter, any other day of the week in our books!
One thing I'm not clear about, the Euro spec BMW 330d claims 50 mpg while the US spec 335d with a touch more horsepower and marginally quicker performance gets about half the milage?
Perhaps BMW might have considered the 330d in order to better highlight Diesel's "green" advantages. The 330d and 335d both have 3 liter turbo engines, not sure if one is just a detuned version of the other or if they are different enough that they would need to be crash tested separately. In the latter case then you have the answer to the riddle since it makes no economic sense to go though the homologation process for two diesel engines in the US.
And here is the rest of it.
