BARCELONA, Spain (AP) -- Mercedes driver Lewis Hamilton has overcome wet weather and a cold to record the fastest time of the final day of Formula One preseason testing.
Hamilton, who left McLaren for the German team this season, clocked 1 minute, 23.282 seconds on the Catalunya Circuit.
Former teammate Jenson Button steered his McLaren to the session's second-best lap, followed by Jean-Eric Vergne of Toro Rosso.
Practice was interrupted by eight red-flag stoppages for slippery conditions on the track.
Preseason testing returns to northeastern Spain from Feb. 28 to March 3 before the season-opening Australian Grand Prix on March 17.
