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. More spacious, practical, advanced and efficient than its predecessor, it offers impressive accommodation with 610 litres of boot space (1,800 litres with rear seats folded). The interior is finished to BMW's usual upmarket standards, featuring dual-zone climate control, Bluetooth connectivity, adaptive LED headlights, satnav, parking sensors, heated front seats and a powered tailgate as standard.

The engine line-up is excellent, with options including a 2.0-litre four-cylinder 630i, a 3.0-litre six-cylinder 640i xDrive, and efficient diesel variants in 630d or 630d xDrive specification. The 630d achieves an impressive 55.3mpg claimed, with real-world figures around 50mpg, whilst the 640i xDrive manages 34.4mpg claimed and approximately 30mpg in real-world conditions. However, the big GT isn't as compelling to drive as competitors, lacking the handling finesse of the BMW 5 Series. Running costs are reasonable for a premium executive car, though five-year VED premiums of £325 apply due to its original list price exceeding £40,000.

Best for: Buyers seeking a large, practical and relaxing luxury car with excellent space and premium comfort, who prioritise practicality over driving dynamics.

Not ideal for: Those expecting sharp handling comparable to a BMW 5 Series, or buyers who prefer more conventional and elegant styling over the Gran Turismo's divisive design.


Comparison vs Key Rivals



The Verdict

You should buy the 6 Series Gran Turismo if: You need a large, practical and relaxing luxury car with excellent space and premium comfort, and prioritise practicality over driving dynamics.

Consider alternatives if: You expect sharp handling comparable to a BMW 5 Series, prefer more conventional and elegant styling, or want a more compelling driving experience.

Competitive Position: The BMW 6 Series Gran Turismo is a unique proposition in the luxury executive segment, offering unquestionable comfort and accommodation with a practical hatchback layout. Whilst it doesn't match the Mercedes-Benz CLS for elegance or the Porsche Panamera for driving engagement, its spacious interior and excellent engine line-up make it appealing for those prioritising practicality and relaxation. The Tesla Model S offers superior technology and performance, whilst the CLS provides more conventional styling. For buyers seeking a large, practical luxury car willing to accept divisive design, the 6 Series Gran Turismo represents a compelling alternative to traditional executive saloons.
