Sebastian Vettel and Mark Webber continued to set the pace on Friday in Austin with the fastest times in the second practice session, although the times continue to be a little suspect because of changing conditions at the Texas circuit. Fernando Alonso was third for Ferrari with the McLarens of Lewis Hamilton and Jenson Button fourth and fifth. Felipe Massa was sixth ahead of Nico Rosberg’s Mercedes, Bruno Senna’s Williams, Kamui Kobayashi’s Sauber and the second Mercedes of Michael Schumacher.
The Lotuses of Kimi Raikkonen and Romain Grosjean were 11th and 13th, split by Pastor Maldonado’s Williams, with Serio Perez behind them. Behind them were the two Toro Rossos, the two Force Indias and the Caterhams, Heikki Kovalainen and Vitaly Petrov being split by Timo Glock’s Marussia, with Charles Pic behind them. At the back were the HRTs as usual.
