Australian Mark Webber has finished sixth fastest after suffering gearbox problems early in his first day of the official F1 test session at Circuit de Catalunya in Barcelona, Spain.
The Red Bull racer completed 97 laps after his world champion teammate Sebastian Vettel completed the previous two days.
Webber’s time was 2.2 seconds behind the fastest of the day set by Williams pilot Pastor Maldonado and was close to two seconds slower than Vettel’s time from the previous day.
The Aussie remained positive however, saying he would've liked a few more laps after completing less miles because of the transmission failure.
"We could have done a bit more, but everybody is in the same boat," he explained. "You always want to do 20 or 30 laps more each day but, in the end, the guys have worked incredibly hard and done a good job. We need to focus on tomorrow now.
"In Jerez I felt comfortable in the car. Today, we didn't have the smoothest of days but there are still loads of positives to look at. Obviously we are a very ambitious team, and we want to keep improving."
Seven-time world champ Michael Schumacher was second fastest on the day with Sauber’s Kamui Kobayashi and McLaren’s Jenson Button completing the top four.
Jean-Eric Vergne was around eight-tenths short of Aussie teammate Daniel Ricciardo's time from the previous day, but the Toro Rosso driver was one place higher than Webber and his best was around three-tenths quicker than the Red Bull.
Ferrari’s Felipe Massa set an identical time to Webber, in 84 laps. But the Brazilian was predominantly on the hard Pirelli tyre.
Teams will one more test at Barcelona on Friday local time before another week of testing on March 1-4
