Robert Kubica was the second fastest driver on the final day of the test in Jerez, as the Renault completed 117 laps.
The dry and sunny conditions in Southern Spain allowed the team to carry out its testing programme, which included evaluation of fuel loads in the morning, and long runs along with set-up work in the afternoon.
Kubica was pleased with the progress made on Day 4, and said that he was happy with the car. “It was a good day and we tried a lot of different things, which has given us lots of useful information. To begin with we did some evaluation with different fuel loads to check the balance of the car and then in the afternoon we did long runs with heavy fuel to simulate a race distance. We completed most of the programme and I was pretty happy with the car.”
Alan Permane, the Chief Engineer summed up Renault's day. “[It was] another solid day of work as we made the most of the good weather. We ran the car with varying fuel loads this morning to see how it reacted and we were pleased with the results. Then we attempted a race simulation and, although it was interrupted, we still managed to cover the required number of laps. Later in the afternoon we concentrated on some set-up work and found a good direction with the car.”
Renault will resume testing in Barcelona on Thursday. New driver Vitaly Petrov will be in the car for the first two days and Kubica will return to the car on Saturday and Sunday.
