Bentley developing V8 engine with Audi
The 4.0-litre direct-injection unit will help to lower the average fuel consumption and emissions of both makers’ ranges. However, the partners are remaining tight-lipped about further details at this stage, apart from saying that its CO2 output will be 40% below that of the W12 unit in the car.
‘We are adapting it four our purposes so that it delivers Bentley driving characteristics [lots of low-to-mid-range torque],’ says Brian Gush, Bentley’s director of chassis and powertrain. He would not say whether it is turbocharged, but added: ‘It does not have a conventional layout.’
The 6.0-litre W12 engine has also been reworked for the new GT and now delivers increased power and torque with lower consumption and emissions, helped by a 65kg weight reduction in the new car.
‘We’ve continued to refine it throughout its life and have now reduced internal friction and fitted lighter components,’ says Gush. Bentley remains far and away the largest producer of 12-cylinder engines in the world.
The new Continental GT is based on the same underpinnings as the current model, but there have been improvements to the gearbox, four-wheel-drive system, stability control and chassis.
This has completely changed the car’s character, says Gush. ‘It’s been sharpened up and made more focused. The ESP [stability control] has been tuned to take advantage of the more rear-biased torque split and the wider tracks on each axle. It recognises when the driver knows what he’s doing and will not intervene.’
The car has been totally redesigned inside and out, but is still instantly recognisable as a Continental GT, says Gush. It also shows great attention to detail in the quest to save weight – moving the front seat belts from the seats to the door pillars has shaved 18kg off the car and also helped to create a bit more rear space by allowing thinner front seatbacks.
The new car goes on sale in the first quarter of 2011, priced at £135,760, but the more powerful two-seater Supersports version of the current Continental GT remains in production.
