Robert Kubica has declared himself happy with the progress shown by Renault during the opening two tests of the 2010 F1 season.

Despite mixed weather conditions at both Valencia and Jerez, the Enstone-based squad has been able to complete more than 2000km of running with the R30 and - with more still come from the car - Kubica insisted the team was heading in the right direction.

"Although the bad weather has affected our track time, we've made a lot of progress, particularly last week in Jerez where we found some good performance," he said. "What is important is that the car is not too sensitive and that makes it easier to find a good set-up.

"There are a few things still to come for the other tests that will make me feel even better in the car and which will also make it quicker, but we're definitely moving in the right direction."

Kubica added that he already felt at home within the Renault team having made the switch from BMW Sauber over the winter, insisting his time with the team had been 'as he expected'.

"It already feels like home and it's a nice group of people to work with," he said. "I had an idea of what Renault would be like before I joined and it has been just as I expected. The team is very motivated and looking forward to the big challenge we have ahead of us to bring Renault back to the front of the grid.

"Everybody is working hard and it was nice to see such a quick response from the guys in the factory to make the changes we needed after the Valencia test in time for Jerez."
