Which is better for mpg? A 6-year old BMW 330CI auto or a 6-year old BMW X5 Sport 3.0 petrol auto?

Answered by Honest John
The 330CI auto. Less weight. Less wind resistance. Narrower tyres.

Real MPG enables you to register the fuel economy you are actually getting against your make and model of car, its engine and type of transmission.

Every time you enter an average consumption figure against your car, the overall average automatically adjusts to reflect it.
