Bruno Senna said he was pleased with his first run in the new Renault R31 after taking part in the final day of the four-day pre-season test at Jerez.
The Brazilian took over from Nick Heidfeld for the final day of the session, which marked his first chance to run on Pirelli tyres and his maiden opportunity to sample a cars fitted with both KERS and the new adjustable rear wing.
Although he is set to be overlooked for a race seat in favour of Heidfeld as Renault looks to replace the injured Robert Kubica, Senna impressed on track with the fifth quickest time although he was prevented from chasing a quicker time late on when rain started to fall.
Despite that, he managed to set a time quicker than race driver Vitaly Petrov had managed during his two days on track.
“It was an awesome day - my first chance to drive the R31 and I'm pleased with how things went,” he said. “It was very much a learning day for me. I had never used the adjustable wing or the KERS before, so I had to adapt to these. It's not easy at first, because there is a big workload and you are operating two factors that change the balance of the car, but by the end of the day it became more like second nature.
“I started the day pretty relaxed; gradually built up my confidence, and then by lunchtime I was feeling pretty comfortable with things. I was looking forward to doing some hard laps at the end of the day, but with the red flags and the weather, there wasn't enough time.”
