King Charles has been campaigning for more sustainable choices long before it was trendy. From organic farming to climate change, he's been pushing environmental issues for decades, and this extends to the vehicles he drives. Princess Anne might be famous for wearing dresses and coats from the '70s, but The King still drives the 1969 Aston Martin DB6 Volante he received as a 21st birthday gift—and it has a very unusual operational system.
In 2021, The King (then the Prince of Wales) told the BBC, "My old Aston Martin, which I've had for 51 years, runs on—can you believe this — surplus English white wine, and whey from the cheese process." In official terms, it's known as E85 bio-ethanol and is produced from 15 percent unleaded gas and 85 percent leftover wine and cheese whey produced on the Duchy of Cornwall estate.
