Former champion Lewis Hamilton will move to Formula One's Mercedes team next year from McLaren, leaving seven-time champion Michael Schumacher without a confirmed ride in 2013.
Separately, Formula One announced its 2013 schedule that includes two U.S. races: The inaugural Grand Prix of America at Port Imperial in New Jersey on June 16, and the U.S. Grand Prix in Austin, Texas, on Nov. 17.
Hamilton signed a three-year contract with Mercedes. The British driver, who won the 2008 championship, is fourth in this year's title standings.
"It is now time for me to take on a fresh challenge and I am very excited," Hamilton, 27, said in a report on Formula One's website.
