Improvements to the powerful engines available can't disguise fairly woeful fuel economy

2.5 out of 5

​​At the top of the Continental GT range, you’ll still find a massive 6.0-litre W12 twin-turbocharged petrol engine in the Speed, while it can also be equipped in the incredibly lavish GT Mulliner as an option. The W12 will suit buyers who simply want the ultimate Bentley experience, but many buyers are likely to be more interested in the smaller V8. Despite the difference in capacity, both engines share a decidedly 'healthy' thirst for fuel.

Bentley Continental GT MPG & CO2

The W12 is a brand new engine that comes with an up-to-date eight-speed dual-clutch automatic gearbox and cylinder-deactivation technology, that saves fuel by shutting down part of the engine when you don’t need it. However, the W12 is still an incredibly thirsty engine, with an official economy figure of 20.6mpg and CO2 emissions of 311g/km.

The V8 model claims a fuel economy of 23.3mpg and CO2 emissions of just over 270g/km, so the improvement over the W12 isn't as much as hoped. Both versions are comfortably in the top BiK band for anyone brave enough to run either of them as a company car. The Continental GT sits in the standard VED (tax) band, but there's a surcharge in years two to six owing to the car's high list price.

Insurance groups

You’ll most likely be on first-name terms with your insurance broker if you’re planning to cover a new Continental GT, and needless to say, it sits in group 50 – the most expensive position. 

Warranty

Every Bentley comes with a three-year/unlimited-mileage warranty, which is relatively standard for the class, matching the cover for an Aston Martin DB11 and Mercedes-AMG GT.

Servicing

After investing in a Bentley, you’re likely to want to keep it in good shape and worth as much as possible. Official Bentley services are recommended annually (or after 10,000 miles) and include genuine replacement Bentley parts with get their own two-year warranty. It’s likely to be quite pricey, though, and it might surprise many to note that Ferrari maintenance is free for the first seven years of ownership.
