Bentley showcases the power of renewable fuel at Goodwood

Bentley has taken on the Goodwood hill climb with a renewably-powered showcase - a Bentayga EWB powered by second-generation renewable fuel made from agricultural waste straw.

But the Bentayga EWB was not just powered by renewable fuel (as will all modern Bentleys running on the hill climb this year) - it also opened an unofficial, new record for the fastest car with a trailer. The hill climb was completed by the Bentayga in just one minute and 21 seconds, a fact made more impressive by the fact that it was towing 2.5 tonnes of straw in a specially-prepared trailer from U.K.-based trailer manufacturer, Ifor Williams.

Bentley states that the renewable fuel will see an 85% reduction in carbon emissions on a well-to-wheels basis. The 2.5 tonnes of straw hauled to the top of hill, meanwhile, is said to be enough to create 1,770km worth of fuel that the Bentayga EWB, and indeed all Bentleys, can run on without modification.

Following its successful ascent, both the Bentayga EWB and its trailer are on display in the Cathedral Paddock at the Festival of Speed, while a short film covering the run will be shown during the event.
