BMW 6 Series Gran Turismo (2018-2020) Pros and Cons

Pros	Cons
An interesting alternative to a conventional executive car	The xDrive 4x4 versions cost more to fuel than two-wheel-drive models
The hatchback layout is practical and there's plenty of luggage space	Not as compelling to drive as a BMW 5 Series
Four-wheel drive is available with some engines	Divisive looks may put you off

Quick Summary

The BMW 6 Series Gran Turismo (2018-2020) is a large and practical executive car that blends tried-and-tested BMW underpinnings with a coupe-like body and practical hatchback layout. Launched in 2017 as the successor to the 5 Series Gran Turismo, it offers significant improvements in spaciousness, practicality, and efficiency. With 610 litres of boot space (expanding to 1,800 litres with rear seats folded), a powered tailgate, and premium interior finishes, it's unquestionably accommodating for those seeking comfort and luxury.

The engine line-up is excellent, featuring the 2.0-litre 630i, 3.0-litre 640i xDrive, and efficient diesel options in 630d and 630d xDrive specifications. The 630d achieves an impressive 55.3mpg claimed, with real-world figures near 50mpg, whilst the 640i xDrive manages 34.4mpg claimed. However, the car is big, heavy, and uncommunicative to drive, lacking the handling appeal of competitors. Running costs are reasonable for its class, though five-year VED premiums of £325 apply due to its original list price exceeding £40,000. BMW Service Inclusive plans offer cost certainty for maintenance.

Best for: Buyers seeking a spacious, comfortable, and luxurious executive car with practical hatchback versatility and excellent engines, particularly those valuing relaxation over dynamic driving.

Not ideal for: Drivers prioritising engaging handling, those seeking a sleek aesthetic, or buyers wanting a car that drives like a conventional BMW 5 Series.


Comparison vs Key Rivals



The Verdict

You should buy the 6 Series Gran Turismo if: You're seeking a spacious, comfortable, and luxurious executive car with practical hatchback versatility and excellent engines, particularly valuing relaxation over dynamic driving.

Consider alternatives if: You prioritise engaging handling, seek a sleek aesthetic, or want a car that drives like a conventional BMW 5 Series.

Competitive Position: The BMW 6 Series Gran Turismo is a distinctive choice in the luxury executive segment, offering unmatched practicality and comfort through its hatchback layout and spacious interior. Whilst it doesn't match the driving dynamics of the Porsche Panamera or the sleek appeal of the Mercedes-Benz CLS, it provides a compelling alternative for those prioritising space and relaxation. The Tesla Model S offers cutting-edge technology and performance, but at a premium. For buyers valuing comfort, practicality, and luxury over sportiness, the 6 Series Gran Turismo remains an excellent and increasingly affordable used option, especially as depreciation has made it more accessible.
