What is it?
One way to consider BMW’s ActiveHybrid 3 is as a faster, more economical version of the six cylinder 335i M Sport.
A hybrid performance car may seem odd when your usual thought is of a Prius, but that’s how BMW pitches this undeniably rapid machine, which knocks off the 0-62mph dash in 5.3 seconds. And impressively, scores 139g/km and 47.9mpg.
The £37,540 335i, by contrast, needs 5.9sec for the same feat, emits 186g/km of CO2 and returns 39.2mpg combined. So far, so good.
Trouble, there’s another way to consider this car, which is as an alternative to the 330d SE. Also a six, it costs £6945 less at £33,280, puts out 129g/km of CO2, returns 57.6mpg and accelerates to 62mph in 5.6sec.
So why does BMW bother with the complexity of a hybrid to achieve numbers inferior to its excellent diesel? Partly because of the diesel-unfriendly US market, and partly because it feels it must be present with this technology, which it now offers in four models, three of them here.
