Full FP1 timesheet HERE
Lewis Hamilton set the fastest time of FP1 for the Abu Dhabi Grand Prix as Mercedes held a huge advantage over the rest of the field.
While the two title protagonists of Hamilton and team-mate Nico Rosberg were separated by just 0.133s, Fernando Alonso in third place was a massive 1.7s slower than Hamilton as the early signs showed no outside threat to the championship battle.
Alonso edged out Sebastian Vettel and Daniel Ricciardo as the trio were covered by just 0.16s, while the two Toro Rossos of Jean-Eric Vergne and Daniil Kvyat were next quickest on the timesheets.
Valtteri Bottas was eighth fastest but completed just eight laps as he suffered an unusual failure just half an hour in to the session. Bottas returned to the pits with the whole sidepod cover missing from his car, with it left on the track on the approach to Turn 11. At the same time, team-mate Felipe Massa was called in to the pits as the team was forced to repair the fixings on both chassis and he finished the session in 13th place with just seven laps completed.
Sergio Perez and Nico Hulkenberg rounded out the top ten, just ahead of Kevin Magnussen in the updated McLaren. Magnussen's team-mate Jenson Button was down in 17th place after his session was cut short after just eight laps, leaving him slower than Lotus FP1 debutant Esteban Ocon.
Kamui Kobayashi was 4.5s off the pace on Caterham's return but managed 22 laps and finished the session marginally quicker than another FP1 debutant in Sauber's Alex Fong. Caterham's Will Stevens was slowest in the opening session of his first grand prix weekend as car problems meant he could only complete 12 laps.
