Jarno Trulli insisted he had had a positive first day behind the wheel of the new Team Lotus T128, despite being unable to set a meaningful lap time in Valencia.
A lack of power steering on the car after the problems encountered by Heikki Kovalainen yesterday meant the Italian spent the entire day completing a series of system checks rather than chasing a time.
Trulli will now aim to find out more about the performance of the car when the team remains in Valencia tomorrow for a private test.
"It has been a very positive first day, despite the fact we deliberately didn't set any meaningful laptimes as the car is missing a few parts that will be with us tomorrow,” he said. “Nevertheless, the car feels great – it has good grip and today we were able to concentrate on carrying out work on the systems which we were going to have to do at some point anyway.
“Now we can concentrate on building up the performance levels tomorrow and in the next tests, so while it's a shame I couldn't have a full taste of the car, it was still a very positive first day in the new car."
Technical director Mike Gascoyne praised Trulli for completing the programme without any power steering and confirmed that the parts would be back at the circuit for Friday's running – when Heikki Kovalainen will also be in action behind the wheel.
"We had a limited programme today due to the lack of power steering on the car,” he said. “Under those circumstances 38 laps was the full programme and I want to say well done to Jarno for completing the plan in a car that was clearly hard work to drive.
“On the positive side we have now completed the systems checks on fuel, aerodynamics and cooling and were able to do start simulations, so with the fact we have another full day of testing tomorrow with both race drivers and the power steering we are aiming to step up to focusing on performance on our third day in Valencia."
