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 spacious hatchback layout. Launched in 2017 as the successor to the 5 Series Gran Turismo, it offers significant improvements in space, practicality, and efficiency. With 610 litres of boot space (expanding to 1,800 litres with rear seats folded), it's unquestionably accommodating inside, featuring premium upmarket finishes and extensive driver seat adjustment for comfort. The powered tailgate and low boot lip make loading straightforward, whilst longer items can be carried with ease thanks to the near-flat rear floor.

The engine line-up is excellent, featuring the 2.0-litre 630i, 3.0-litre 640i xDrive, and efficient 630d diesel options. However, the car's big, heavy, and uncommunicative nature blunts driving enjoyment, with many competitors offering superior handling. Running costs are reasonable for a premium vehicle, with the 630d achieving around 50mpg in real-world conditions and the 640i xDrive returning close to 30mpg. Be aware of hefty five-year VED premiums of £325 due to the car's high list price. Whilst divisive styling and uninspiring dynamics may deter some, those prioritising comfort, space, and relaxed luxury will find much to appreciate.

Best for: Buyers seeking a large, practical, and comfortable luxury executive car with excellent space and premium refinement, particularly those who value hatchback practicality over conventional saloon styling.

Not ideal for: Drivers prioritising engaging handling dynamics, those seeking sleek and elegant styling, or buyers wanting a car as compelling to drive as a BMW 5 Series or Jaguar XJ.


Comparison vs Key Rivals



The Verdict

You should buy the 6 Series Gran Turismo if: You're seeking a large, practical, and comfortable luxury executive car with excellent space and premium refinement, particularly if you value hatchback practicality over conventional saloon styling.

Consider alternatives if: You prioritise engaging handling dynamics, sleek and elegant styling, or want a car as compelling to drive as a BMW 5 Series or Jaguar XJ.

Competitive Position: The BMW 6 Series Gran Turismo is an interesting and practical alternative to conventional executive cars, offering impressive space and premium comfort. Whilst it doesn't match the sleek appeal of the Mercedes-Benz CLS or the driving dynamics of the Porsche Panamera, its hatchback practicality and spacious interior make it compelling for those prioritising comfort and accommodation. The Tesla Model S offers superior user ratings and forward-looking technology, but the BMW remains a strong choice for buyers seeking traditional luxury with practical versatility. Its divisive styling and uninspiring dynamics prevent it from being a top-tier recommendation, but depreciation has made used examples increasingly attractive for those valuing space and refinement over outright driving engagement.
