BMW 3 Series GT running costs should be in line with rivals. The most frugal engine will be the 143hp 2.0-litre diesel unit in the 318d. It has a claimed figure of 62.8 when mated to the manual ‘box – expect high 50s in real world driving.

BMW 3 Series Gran Turismo emissions are fairly low. The most environmentally friendly GT is the 143hp 2.0-litre diesel unit in the 318d in SE trim. It emits 119g/km when using the manual gearbox. The fastest and most powerful BMW 3 Series GT as expected emits the highest amount of CO2 at 188g/km.

Even though this is a new product, BMW 3 Series Gran Turismo reliability levels should prove to be excellent.

The majority of engines and mechanicals are well-proven and the German marque fares well in reliability surveys.

The current generation of 3 Series saloon and Touring models have been largely problem-free and we expect this GT version to be just as well-built.
