Bentley’s new 616hp 12-cylinder GT Speed convertible with 8-speed and energy recuperation improves fuel economy by 15%

Bentley will introduce the new Continental GT Speed Convertible at the North American International Auto Show in Detroit this month. The new GT Speed Convertible shares its powertrain specification with its Bentley stablemate, the GT Speed coupé: a 616 bhp (459 kW) twin-turbocharged 6.0 liter W12 combined with a close-ratio eight-speed ZF transmission to deliver a 15% improvement in fuel economy.

Provisional EPA fuel economy ratings for the convertible are 12 mpg city, 20 mpg highway, and 15 mpg combined. Provisional EU cycle fuel consumption figures are 22.7 l/100km urban, 10.4 l/100km extra-urban, and 14.9 l/100km combined.

The twin-turbocharged, 48-valve, W12 engine powers the new convertible to 60 mph in 4.1 seconds (0-100 km/h in 4.4 s) and onto a top speed of 202 mph (325 km/h). Zero to 100 mph (160 km/h) takes 9.7 seconds. Peak torque of 800 N·m (590 lb-ft) is reached at 2000 revs/min through to 5000 revs/min.

The latest ME17 engine management system provides enhanced turbocharger control and torque management. In common with all W12-engined models, the GT Speed convertible features an energy recuperation system. Together with a close-ratio, quick-shifting eight-speed transmission, this has resulted in the 15% improvement in fuel economy and CO2 emissions compared with the first generation Speed, with a commensurate increase in tank range.

Switching the gear selector to ‘Sport’ mode delivers a sharper throttle response, gear-shifting at higher engine speeds and faster ‘block shifting’ (e.g. 8th direct to 4th gear).

The Electronic Stability Control (ESC) system is optimized for the new engine management system to deliver both safety and greater driver involvement. The ESC system retains the “Dynamic Mode” setting that allows increased wheel slip at higher speeds, with engine torque reinstated more quickly after a system intervention.



Listen, when a car gets 15mpg there is no point in bragging about how they improved mpg by 15%. These kinds of cars should be illegal.


The person who buys one is a gashog who has no respect for his fellow man.

@Jus7tme: Why should they be illegal--sounds like fun to me. Wasteful of fossil fuels, perhaps. Nothing a good carbon tax couldn't fix. Better yet, imagine a world with cheap, abundant nuclear power which, besides obsoleting coal power plants, can synthesize liquid hydrocarbons for our transportation needs.

Hair shirt strategies are losers. It's a new year--think positive!


A few hundred Bentleys sold in the U.S. this year will not matter, it is the more than ONE MILLION 3/4 ton pickup trucks that will consume a lot of fuel, while most of them are NOT used for work.

Sure it is a fun. It is a rollercoaster of a drive with 0 to 60 in 4.1 sec versus 4.4 sec for Tesla's fastest Model S. I don't personally like it is so wasteful when other people have a hard time paying for gasoline. However, that is not enough for me to support limiting the life styles of other people by prohibiting it. Freedom to live as we please is more important as long as it does not directly hurt other people. Nor would I support prohibiting obesity even though that is just as disrespectful of those who have a hard time affording to buy food. Think about it. If you felt so good about yourself that you would drop all of your relations that where morally questionable in some sense be it obesity, extravagant lifestyle, hard-line political or religious beliefs, gambling, sexual orientation, illegal or legal narcotics like alcohol or cigarettes, etc then how many people would there be left in you network?

I am optimistic. We still need to see a four wheel drive Model S from Tesla and that would surely beat the 4.1 sec of this very cool Bentley.



A person who buys one, isn't going to be commuting 60 miles a day to work.


The person who buys one may not drive it much at all.

Who is more hog than someone who uses some of my tax money to buy a hybrid and then drives little and we would all be better off if they were in a pickup.
