Sebastian Vettel set the fastest lap of the first practice session in Austin, Texas, 1.4secs ahead of Lewis Hamilton and more than two seconds faster than his championship rival Fernando Alonso. The track was very green with drivers complaining of wheel spin on the slippery tarmac. As a result there were a few spins and offs, but this is a modern track and there is little to hit. Fourth fastest was Jenson Button ahead of Mark Webber, Felipe Massa, Nico Hulkenberg, Kamui Kobayashi, Nico Rosberg, Sergio Perez, Paul di Resta and the two Toro Rossos of Daniel Ricciardo and Jean-Eric Vergne. The Lotus team did not look very strong with Kimi Raikkonen and Romain Grosjean 14th and 15th, ahead of Pastor Maldonado, Michael Schumacher and Charles Pic, ahead of the two Caterhams of Heikki Kovalainen and Vitaly Petrov. Timo Glock was next, ahead of Bruno Senna and the HRTs of Pedro de la Rosa and Ma Qing Hua.
