- Lewis Hamilton plays down Formula One title talk
- Former world champion records fastest lap on final day of testing
- McLaren's Jenson Button and Toro Rosso's Jean-Eric Vergne next quickest
- Mexico's Sergio Perez fastest man of the week in his McLaren
Lewis Hamilton defied the conditions to record the fastest lap on the final day of Formula One testing at Barcelona Friday -- but the Briton refused to entertain any title talk.
Hamilton, who quit McLaren to join Mercedes at the end of last season, beat former teammate Jenson Button into second place with Torro Rosso's Jean-Eric Vergne in third.
Hamilton clocked a time of 1 minute 23.282 seconds, despite the constant rain and adverse weather at the Spanish circuit.
But the 2008 world champion insists his team is not ready to compete with the likes of Red Bull's triple world champion Sebastian Vettel and Ferrari's Fernando Alonso when the new season starts in Melbourne on March 17.
"I think people are talking us up at the moment," Hamilton told reporters.
