There are many factors that will affect performance though and in a hybrid engine the effect of the battery will augment the power of the engine. Perhaps that's why the Activehybrid has the more relaxed final drive ratio.

Interesting. So does this drive ratio also apply to reverse gear? If the ActiveHybrid 3 is 2.81 and the 335i is 3.15, then does that mean that the ActiveHybrid 3 can go faster in reverse since the engine will spin slower at a low speed? Or is it the opposite, or is this a completely wrong example?
