Mark Webber headed the first practice session for the Brazilian Grand Prix.
The Red Bull pilot was just 14 thousandths of a second quicker than Jenson Button.
The McLaren and Red Bull cars swapped fastest times during the session. Lewis Hamilton was third quickest ahead of Sebastian Vettel, the world champion wearing a new helmet-mounted camera during the session.
The two Ferraris of Felipe Massa and Fernando Alonso were next. Alonso’s session came to an end when his engine failed five minutes before the chequered flag came out.
Romain Grosjean, driving Vitaly Petrov’s car, also came to a stop before the end of the session with a technical problem on the Renault.
Several other teams ran one-off drivers during the session. Nico Hulkenberg was eighth-quickest for Force India behind Michael Schumacher.
Jean-Eric Vergne was 18th for Toro Rosso, Luiz Razia 20th for Lotus and Jan Charouz last in the HRT.
Kamui Kobayashi had a minor spin during the session but didn’t hit anything and ended up 15th-fastest.
