Trulli: Toyota must keep work ethic

Trulli has helped the Japanese car manufacturer emerge as one of the leading teams in the fight behind Ferrari, McLaren and BMW Sauber, but is aware they cannot afford to relax their efforts yet.

"I am very happy with my start to the season; the new car has been strong, the team has worked really well and we have got the results we deserved," said the Italian, who has been further encouraged by Toyota's form after trying out their Barcelona upgrades last week.

"But I am not getting carried away because I know we must continue to work hard to stay in this position and hopefully close the gap on the top three teams.

"We had a successful test in Barcelona last week with the new package so we should be in good shape this weekend, but the battle is so close we cannot afford any mistakes. I think we have proven we are leading the second group of cars at the moment so we should go to Spain expecting to qualify in the top 10 and finish in the points.

"It would be great to fight for the top six again but we'll see how it goes because we are not quite on the same level as the leading teams at the moment."

The improvements to the TF108 include a new front wing, engine cover and rear wheel rim covers, as well as modifications to the suspension and brakes.

Toyota's senior general manager of chassis Pascal Vasselon is confident that the revisions will lift his team's performance in this weekend's Spanish Grand Prix.

"We tested the new package at Barcelona last week and the results were in line with our expectations so we should see a performance increase," he explained. "I expect us to build on our strong performances so far this season and hopefully score points with both cars."
