Button pleased with final test of year.

Jenson Button has said that Honda's test at Jerez last week went well for the Brackley-based squad.

Honda need to make dramatic progress over the winter, after a dismal 2007, in which they scored only 6 points and plummeted down to eighth in the constructors' championship, ahead of only Super Aguri and Spyker.

Button, who began the four-day test for the outfit on Tuesday, before handing the car over to Rubens Barrichello and Anthony Davidson, spent his day focusing on development work on the new electronics, as well as completing an initial evaluation with the 2009 'slick' development Bridgestone tyres.

"The test in Jerez went well," confirmed the Englishman, who did 70 laps and who ended proceedings second quickest overall on day 1. "I continued our work from Barcelona last month concentrating on the evaluation of the new electronics system which is compulsory for all teams next year.

"There are no driver aids with this system, which means no traction control and no engine braking control, and I thoroughly enjoyed it. You have to be very smooth and progressive with the throttle, which suits my driving style.

"I also had the opportunity to run on the slick tyres and that was fun. It was the first time that I have driven with slicks on an F1 car and I really enjoyed it. Obviously the downforce levels in 2009 will be different but I had a good feeling from this short trial."

Barrichello, who ran on days two and three, also reckoned that things had gone well, although he was slightly frustrated by the number of red flags. The Brazilian still managed 103 tours on Wednesday though and 89 laps on Thursday.

"It was very nice to be back driving the car this week for my first test since the last race of the season in Brazil," he continued. "I had two good days of running without traction control as we worked on the development of the new electronics system to prepare for next year's regulations.

"The only issue this week was the number of circuit red flags which seemed to happen whenever we tried to run on new tyres, so there was certainly a better lap time possible. It was also good to be using slick tyres once again this week."

Steve Clark, Honda's head of race and test engineering, meanwhile echoed the thoughts of Button and Barrichello: "This week's test was our second session with the new electronics system. Recent work on the engine dyno has rectified the power delivery issues that we identified three weeks ago in Barcelona and has seen us make good progress on the track. This, and other work underway to adapt to the 2008 electronics regulations, is useful preparation ahead of the debut of the RA108 early next year and for this reason it has been a very productive test," he summed-up.
