Sebastian Vettel has said that he is lost for words following his record-breaking victory at the United States Grand Prix, which was his first at the Americas track in Austin, Texas.
The Red Bull driver finished ahead of Lotus Renault's Romain Grosjean and teammate Mark Webber to become the first man to win eight races in a row.
"I don't know how I do it if I'm honest," the 26-year-old said in his post-race interview. "It's impossible to know what to say.
"The car was fantastic. It was a bit tight at the start, Romain had a good start and I didn't know if it would be enough.
"We had good pace, though, and could control the gaps for eight wins in a row."
It is the seventh time Vettel has converted pole position to victory in 2013.
