The new BMW 3 Series grows even larger than before and now measures 4.71 metres long. Half of the increase is attributable to the wheelbase so that the saloon can now offer more space inside. 

Internationally, the updated engine range consists of two petrol-fueled and two diesel-fueled four-cylinder engines, in addition to a diesel-fueled six-cylinder. 

In the months after launch, a petrol-fueled six-cylinder joins the range, and a plug-in hybrid arrives later, too.
