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. The 610-litre boot expands to 1,800 litres with rear seats folded, making it unquestionably accommodating for those needing premium space. Two trim levels—SE and M Sport—come well-equipped with features including dual-zone climate control, Bluetooth connectivity, adaptive LED headlights, satnav, and parking sensors as standard.

Engine options include the 2.0-litre 630i, 3.0-litre 640i xDrive, and 3.0-litre 630d diesel variants, all paired with an eight-speed automatic gearbox. The 630d achieves an impressive 55.3mpg claimed, whilst the 640i xDrive manages 34.4mpg. However, the car is big, heavy, and uncommunicative, lacking the handling appeal of competitors like the BMW 5 Series or Jaguar XJ. Its divisive styling and high running costs—including a hefty five-year VED premium of £325—may deter some buyers. Despite these drawbacks, it remains an excellent choice for those prioritising comfort, pace, and practicality in a premium package.

Best for: Buyers seeking a large, practical, and relaxing luxury car with excellent space and premium comfort, and those wanting an interesting alternative to conventional executive saloons.

Not ideal for: Drivers prioritising engaging handling, those seeking a sleek and elegant design, or buyers concerned about fuel costs with four-wheel-drive models.


Comparison vs Key Rivals



The Verdict

You should buy the 6 Series Gran Turismo if: You're seeking a large, practical, and relaxing luxury car with excellent space and premium comfort, or wanting an interesting alternative to conventional executive saloons.

Consider alternatives if: You prioritise engaging handling, seek a sleek and elegant design, or are concerned about fuel costs with four-wheel-drive models.

Competitive Position: The BMW 6 Series Gran Turismo is a capable executive car offering impressive practicality and comfort, but it faces stiff competition from more elegant and engaging alternatives. Whilst the Mercedes-Benz CLS and Porsche Panamera offer superior styling and driving dynamics, and the Tesla Model S provides cutting-edge technology, the 6 Series GT remains a solid choice for those prioritising space and relaxation. Its divisive looks and less compelling handling mean it's best suited to buyers who value practicality and premium comfort over aesthetic appeal or driving engagement. For those willing to compromise on style and dynamics, it represents good value in the luxury executive segment.
