Sebastian Vettel Dons Mario Kart Costume For Red Bull Soapbox Derby In Germany (VIDEO)

When you're three-time Formula 1 world champion there's only one logical next step for your career - Mario Kart.

That's exactly the conclusion Sebastian Vettel appears to have reached, as he donned a fetching red costume and climbed into a suitably comic racer for a recent PR stunt.

Vettel was part of the jury at the Red Bull Soapbox Race in Germany this weekend but obviously jumped at the chance to have a go at the 500m course himself.

He got an rapturous reception from the crowd - though possibly not as loud as the one that cheered his victory in the German Grand Prix the previous week.
