The Renault F1 Team completed its final day of testing in Jerez as third driver Lucas Di Grassi covered 123 laps behind the wheel of the R29. Ho-Pin Tung also had the chance to drive a handful of extra laps in the damp conditions, adding to the 67 laps he completed yesterday.

Conditions were overcast for the morning with a light rain shower just before lunch leaving the track damp for the middle part of the day. However, conditions improved in the afternoon, allowing Lucas to complete the team's technical programme. The priority for the day was to continue evaluating developments for 2010 and to add mileage to new components.

Lucas Di Grassi: "Today was a busy day and I completed over 120 laps. We did lots of different things including some performance work, some long stints and simulations for 2010. It was good for me to get back in an F1 car and the programme over the last couple of days has given me a lot of valuable experience. We managed to complete the most important tasks for the week and hopefully everything we have learnt will help with the development of next year's car."

Alan Permane, Chief Race Engineer: "We had a productive day of testing with Lucas with the programme based around preparation for next year. We ran the car quite heavy in the morning as we did some work on the brakes and then in the afternoon we completed some back-to-back testing on the front and rear suspension. While the track was damp we put Ho-Pin back in the car to give him the chance to experience an F1 car in wet conditions. Overall it has been a successful week for us: the team has worked hard and we've come away with a lot of valuable data which will be useful for the development of next year's car."
