Bentley Continental GT vs BMW M8: UK prices compared
As of 14 November 2026, 175 Bentley Continental GT and 14 BMW M8 are for sale at UK specialist dealers. The typical asking price is £134,850 for the Bentley Continental GT and £53,990 for the BMW M8.
The Bentley Continental GT is a large, all-wheel-drive grand tourer, built since 2003 with W12, V8 and now plug-in hybrid V8 power. The BMW M8 is the M division's version of the 8 Series, with a twin-turbo 4.4-litre V8 and xDrive all-wheel drive, sold as a coupé, convertible and four-door Gran Coupé. Both are fast, expensive two-door cruisers with four seats, so buyers often weigh one against the other.

Which to choose
The Bentley Continental GT suits
Buyers who want a long-distance car built for comfort, refinement and a hand-finished cabin, and who like having choices: two decades of models, W12, V8 or hybrid engines, and coupé or convertible bodies across a broad spread of ages.
The BMW M8 suits
Buyers who want a sharper, lighter car that is still at ease on a long trip, and who value the M8's agility on a good road. The Gran Coupé adds a pair of rear doors and usable back seats for those who sometimes carry adults.
Choose the Continental GT if you mainly want comfort, cabin craftsmanship and the widest choice of engines, ages and specifications. Choose the M8 if you care more about how the car handles, since it weighs several hundred kilograms less than a Continental GT Speed, and the Gran Coupé offers more rear space. The newest hybrid Continentals have a large power advantage, but the M8 is quick enough for most drivers. Most buyers end up choosing between luxury and agility.

Questions buyers ask
Which is more powerful, the Continental GT or the M8?
The current Continental GT Speed, a V8 plug-in hybrid, has 771 bhp. The M8 Competition has 617 bhp. Older Continentals with the V8 or W12 engine produce less than the current Speed, so it depends which car you're comparing.
Which has the higher top speed?
The Continental GT Speed's official top speed is 208 mph. The M8 Competition is limited to 155 mph as standard.
Which is lighter?
The M8 Competition. Its official weight is 1,885 kg, against 2,320 kg for the Continental GT Speed and 2,459 kg for the Speed First Edition.
Which is more practical?
Both coupés are four-seaters with small rear seats. The M8 Gran Coupé has four doors and more rear space, so it's the better choice if you regularly carry rear passengers. Neither range includes an estate.
Are both available as convertibles?
Yes. Bentley offers the Continental GT Convertible, and BMW made an M8 Competition Convertible. Far fewer convertible M8s turn up with UK specialists than open-top Continentals.
