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 niche executive car that succeeded the 5 Series GT, blending BMW underpinnings with a large, coupe-like hatchback body. While its styling can be divisive, it excels in practicality, offering a generous 610-litre boot (expandable to 1800 litres) and ample space for all occupants. It features a luxurious interior, high levels of standard equipment even in the base SE model, and the option of M Sport trim.

Equipped with an eight-speed automatic gearbox, engine options include efficient four- and six-cylinder petrol and diesel units. Running costs are reasonable for its class, with the 630d SE often achieving around 50mpg in real-world conditions. However, despite capable engines, its size and weight mean it's not as engaging to drive as some BMW stablemates or rivals. It serves as a comfortable, advanced, and highly practical luxury car, particularly appealing on the used market due to depreciation.

Best for: Drivers needing a large, practical, and comfortable luxury car with impressive space, who appreciate strong engines and good equipment levels, especially as a used buy.

Not ideal for: Buyers prioritising sleek aesthetics, sharp driving dynamics, or a car that feels agile; those who want to avoid the higher VED for cars over £40k new.


Comparison vs Key Rivals



The Verdict

You should buy the BMW 6 Series Gran Turismo if: You're looking for a large, practical, and relaxing luxury car with a comfortable ride, excellent engines, and a well-equipped interior, particularly as a value-for-money used purchase.

Consider alternatives if: You prioritise sleek aesthetics, sharp and engaging driving dynamics, or a car with a more traditional executive saloon or estate body style.

Competitive Position: The BMW 6 Series Gran Turismo offers a unique blend of luxury, practicality, and comfort in the executive segment. While its styling and driving dynamics may not appeal to everyone compared to more conventional rivals like the BMW 5 Series or Audi A7, its immense interior and boot space, coupled with strong engines and a high level of standard equipment, make it a compelling used choice for those prioritising spaciousness and value in a premium package.
