Four-time Formula 1 world champion Sebastian Vettel has made a stunning return in an F1 car at the Goodwood Festival of Speed.
The former Red Bull star drove Williams' iconic FW14B at the famous hill climb, finishing off his run with some doughnuts, all whilst driving on e-fuel.
Vettel has been promoting the use of synthetic fuels since his retirement at the end of the 2022 F1 season, proving that old and modern-day cars can "race without a trace".
"Well, it's just to demonstrate to people that you can literally race without leaving a trace," he said in an interview after his hill climb.
"Obviously, we used synthetic fuels and yeah, as you can see, it's a really old car and it wasn't built around those fuels, but it worked.
"So you've just got to adjust the ECU a tiny bit. But it works for this car, works for modern Formula 1 cars, it works for your road car. It just shows that there is an alternative."
