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. Boot space is 480 litres and the tank holds 59 litres. Ground clearance is a low 135 mm, tuned for road manners. Four paint options are listed, from Arctic Race Blue to Skyscraper Grey. Browse the paint range to finish the picture.

BMW 3 Series power and torque explained

The BMW 3 Series gives you three engines to choose from. There is a 2.0 litre turbo diesel, a 2.0 litre turbo petrol, and a larger 3.0 litre inline-six petrol in the M340i.

The diesel is the calm one, happy to pull from low revs without much fuss. The 2.0 petrol pulls just as early but revs harder and makes far more power. The inline-six is the quickest, with the biggest pull and the highest power of the three.

How to read this chart. Torque is the push you feel when you accelerate, and it peaks low on the rev range. Power is how hard the engine keeps pulling as it revs higher, and it peaks further up. The two dots mark those peaks. The shaded strip between them is the flexibility band: a wider band pulls easily across more revs and feels relaxed in traffic, while a narrower band asks you to rev the engine more to get its best. Use the buttons above to compare this car's engines.

Peak figures come from the 2.0L TwinPower Turbo Diesel spec sheet. The line between the two peaks is not a measured dyno curve.

The 320Ld diesel makes its full 400 Nm of torque low down at 1750 rpm, and builds to peak power of 191 PS at 4000 rpm. That leaves a 2250 rpm working band, the narrowest of the three. It pulls best low down and does not care to rev, so it feels calm in city traffic and relaxed on the open road. Choose it if you cover big distances and want effortless low-end pull with strong diesel economy.

The 330Li's 2.0 petrol puts out the same 400 Nm, and even earlier at 1550 rpm. It then keeps pulling hard all the way to 259 PS at 5000 rpm, a broad 3450 rpm sweep. So it feels easy in city traffic yet has plenty in hand when you floor it to overtake. It suits most buyers who want smooth, quick petrol pace without stepping up to the six. Check the 3 Series on-road number before you decide.

The M340i steps up to a 3.0 litre inline-six, with 500 Nm from 1900 rpm and 374 PS at 5500 rpm. That is the biggest pull and the highest power here, spread across a 3600 rpm band. It surges hard from low down and keeps pulling as the revs climb, so overtakes take barely a thought. Pick this one if you want the quickest, most exciting 3 Series and enjoy revving a petrol out. If you are weighing it against the other two, the full 3 Series Gran Limousine guide lays them out together.
