Renault's Robert Kubica set the pace on the final day of the first Formula 1 pre-season test in Valencia closely followed by Force India's Adrian Sutil and McClaren's Jenson Button.
Kubica, testing Renault's 2011 car - the R31 - set the fastest lap clocking 01m.13.144 seconds, and in the process beat Ferrari's Fernando Alonso's fastest time of 1m.13.307 seconds set in the second day.
Ferrari didn't have the best day on the circuit with their driver Felipe Massa losing a day's running when his car slipped on its own oil after a clamp broke. As a result, the car caught fire and Massa missed more than four hours.
Kubica, who found a lot of pace, didn't allow himself to be carried away by the pace, and said, After we solved the problems with the car we were able to do a little bit of evaluation on the set-up and some tyre work. Unfortunately, because of the morning (he lost time due to car problems) we were not able to complete our program. But better to have problems here than in Bahrain (the first race of the season on 13 March).
It's impossible to compare the car to last year's, and your feeling depends on how things look when everyone is in the same condition running the same time on the track. This we can get only in the Bahrain Grand Prix, so we have to keep pushing and improve the car and solve a couple of issues we had here in Valencia.
Red Bull's Mark Webber, who clocked 1m.13.936 seconds, came in fourth and was 0.3secs away from team-mate Sebastian Vettel's. The Australian came in fourth and was the second fastest 2011 car.
Despite the delay, Massa completed an impressive 80 laps, leading Ferrari's technical director Aldo Costa to say, Looking only at our car, yes we are happy. From a mechanical point of view, the car from here and Jerez will be almost complete but from the aerodynamic point of view there will be further evolutions.
It needs to be a very balanced approach to be a fast and winning car. We know what we have developed from a performance view in the week, we know what we have got from our end to continue the development so we think that we are pushing as much as we can.
Force India's Adrian Sutil, with his 2010 car, was second fastest overall clocking just 0.057secs behind Kubica. Jenson Button came in third for McLaren while Mark Webber made No. 4.
