Robert Kubica insisted he was happy with his first day of running in the new Renault R30, despite ending the first day of F1 testing in Valencia propping up the times.
The Pole was eighth quickest during Monday's running as he and the team focused on getting the car settled and working on weight distribution.
As a result, chasing the quickest time wasn't a priority and Kubica was happy with how his day had gone.
“My first day of testing the R30 went well,” he said. “We had a lot of things to check on the car to make sure they were reliable and all that went smoothly with no big problems to report. Tomorrow we will start working on the balance and trying to understand the car a bit more.
“The narrower front tyres certainly had an impact on the car, but it's difficult for me to judge as this is the first time I've driven the R30. Generally I think they will make the car understeer more in the quick corners.”
Chief race engineer Alan Permane was also happy with what he classed as a 'productive day' with the new machine.
“A fairly positive first day of running with the R30 with Robert in the car,” he said. “We concentrated on putting mileage on the car and spent time getting Robert comfortable in the car. We also started learning about the behaviour of the R30 – what it likes, and how it responds to the narrower front Bridgestone tyres. Then we looked at the brake wear, which will be a key performance factor this year with the cars running heavy fuel at the start of the race. Overall it has been a productive day.”
