Lotus Renault GP man Vitaly Petrov was 'pleased' following the second day of testing at Barcelona.
The Russian not only finished up third fastest on the unofficial times on Wednesday, but he also managed 115 laps in total in the new R31, after simulating a race distance in the afternoon, and using both the hard and soft compound tyres.
“I'm pleased with what we achieved today and I was able to learn a lot about the car and the tyres,” Petrov reflected.
“We spent the morning doing shorter runs and working on the set-up, and I was pretty happy with the car by the end of the morning.
“But the most important thing was to complete the race distance, which we managed this afternoon. It's the first time I've been able to do consistent long runs and really start understanding the tyres.”
Lotus Renault GP chief race engineer, Alan Permane meanwhile was similarly upbeat: “A good day for us. We did some data gathering in the morning, followed by set-up work and then a race distance in the afternoon,” he added. “The focus of the set-up work today was looking at the rear suspension.
"We made various changes during the morning session and found some good directions.”
