Vettel is an aficionado of racing history, but has also been vocal over the need to cut CO2 emissions and tackle climate change.
He combined the two passions on Sunday by running the Williams on carbon-neutral fuel, which is thought to be created synthetically by combining carbon and hydrogen using renewable energy.
Vettel’s blue Mansell-esque overalls include the familiar black strip across the chest, but Williams’ 1992 sponsor Labatt’s is replaced with the “Race without trace” slogan.
“We have to do it in a responsible way,” he added. “So we’re using carbon neutral fuels to demonstrate that we can still hang on to our history and culture in motorsport.
“It’s no different to how the car was thirty years ago, it will sound exactly the same and it will drive the same way.
“I am expecting to have a lot of fun and I hope people can share that because I think it’s an incredible car, the history and the way it sounds.”
