Vitaly Petrov has said his team-mate Robert Kubica gave him no help during his debut season.
Petrov, who will continue with the Enstone-based outfit this year, now re-branded Lotus Renault GP, added that while the data from the Polish driver's car was useful, that was about it.
“If you are team-mates with Robert you cannot learn anything from him because he's a closed person. You just watch his data, how he's working, what he says to the engineers and that's it,” the Russian explained while speaking on the main stage at the recent Autosport International show.
“I didn't learn so much from him, but I learned his way of driving from the data, and I learned from how he talked with his engineers."
Despite a mixed first year at the pinnacle of the sport, Petrov was pleased with his progress and his drive to sixth at the season finale in Abu Dhabi, despite persistent pressure from Fernando Alonso, helped him earn a new two-year deal with the team.
Indeed the 26-year-old really felt things had started to gel and come together by the end of 2010.
“It's like 'welcome to F1', because it's very difficult as a rookie - learning the tracks, the cars and how F1 works,” he continued.
“I had a little bit of pressure, a little bit of nerves, but then finally I found the solution and I think it is working now. Next season I hope will be easier for me,” he summed-up.
