Pedro de la Rosa has kept McLaren's strong testing form going strong, finishing on top at Jerez today.

It seemed to be a bit of a mixed up day though, with a Williams, followed by a BMW in second and third. There were three red flags, and Renault finished down in 13th and 14th.

No wonder, then, that they came out the same day and said they weren't worried about the fact that they haven't exactly shone in testing so far.

Chief test engineer Christian Silk: "We're a strong team and these performances don't worry us. The out and out lap times during the winter are almost impossible to analyse."

Renault have said they aimed to test the reliability and are just happy that they got the miles in, and really it's all down to the weather.
