The BMW 3 Series specifications list three engines, so read them with a fuel choice in mind. The 330Li is a 2.0 litre TwinPower turbo petrol with 255 bhp. The 320Ld is a 2.0 litre turbo diesel with 188 bhp and 400 Nm. The M340i steps up to a 3.0 litre inline six with 369 bhp and 500 Nm. That six peaks between 5500 and 6500 rpm.
Every engine works through an eight speed automatic. The 330Li and 320Ld drive the rear wheels only. The M340i adds xDrive all wheel drive for surer traction. That hardware is the main reason it sits so far above the rest. Match each engine to its variant to keep them straight.
Fuel figures split by engine on the ARAI cycle. The 320Ld diesel leads at 19.61 kmpl, helped by its low end torque. The 330Li petrol returns 15.39 kmpl and the M340i drops to 13.02 kmpl. Those numbers suit their roles, from frugal commuter to quick six. City traffic will pull the real figure below each rating. Read the mileage in more detail.
The Gran Limousine stretches to 4823 mm long on a 2961 mm wheelbase. That extra span is spent on rear knee room. Width is 1827 mm and height 1441 mm, keeping a low sedan stance.
