(CNN) Former "Top Gear" presenter Richard Hammond was in joking mood Sunday, kidding: "I'm not dead," the day after he survived a horrific car crash.

Hammond, who was in Switzerland filming Amazon's "The Grand Tour" was flown to hospital in St. Gallen after the electric supercar he was driving crashed and then burst into flames.

Hammond's co-host, Jeremy Clarkson, said that it was the "biggest crash I've ever seen and the most frightening."
