Prince Charles’ Aston Martin runs on fuel made from wine and cheese

Prince Charles’ Aston Martin gifted to him by Queen Elizabeth II on his 21st birthday runs on wine and cheese, much like a fancy dinner party.

The car uses a combination of English white wine and whey from cheese, the prince said in an interview.

The car, which Charles said he’s driven for more than 50 years, underwent a conversion in 2008 to change its fuel source to bioethanol made from wine and cheese.

The prince asked Aston Martin himself to make the change, but the request was initially met with some skepticism, he said.

“The engineers at Aston said, ‘Oh, it’ll ruin the whole thing,'” Charles said.

“I said, ‘Well I won’t drive it then,’ so they got on with it and now they admit that it runs better and is more powerful on that fuel than it is on petrol.”

“And also, it smells delicious as you’re driving along,” he added.

The bioethanol that goes into the car is a renewable energy source created by fermenting the sugar and starch components of plant byproducts, which can be accomplished using wine and cheese.

The 72-year-old heir to the British throne’s car was a brief talking point in a wide-ranging interview on Monday about the environment and climate change in an interview aired on the BBC on Monday.

Charles said world leaders need to do more than “just talk” when they gather in Scotland’s biggest city, Glasgow, from the end of this month for a U.N. climate summit, known as COP26.

The summit, which is scheduled for October 31-November 12, is being billed by many environmentalists as the world’s last chance to turn the battle against climate change around.

Charles is due to attend a series of events at COP26, alongside the other big names in the royal family including his mother, as well as his eldest son Prince William and William’s wife, Kate, the Duchess of Cambridge.
