Toyota will go into the 2008 Formula One season finale at Interlagos looking to build on the form that has carried them to their second most productive season in the sport.

With two podiums and 52 points in the 17 races prior to the Brazilian Grand Prix, the Cologne-based squad has enjoyed clear improvement as in the two previous seasons combined, it finished on the podium once and scored a total of 48 points.

As well as showing strong performance, the TF108 has also enjoyed good reliability, with only three retirements due to mechanical problems in the 17 races prior to Brazil.

However, despite hitting its pre-season aims, team president John Howett says the team needs to keep working hard to challenge for victory.

"It's great this year to be back on the podium with two drivers and a car that can challenge for podium positions, so it's been a good year," he said. "But the future is the middle step of the podium, number one. There's no doubt in my mind that we will win races and become world champions in the future."

Podium finishes in France and Hungary were the main highs if the year, but the TF108 proved to be competitive at most circuits and has taken six top-ten and 14 points finishes so far.

"I think the biggest fundamental issues are that we have the right number of people in the areas that give performance," Howett continued. "We have a much more detailed and comprehensive database, so we know more about every track and what the key performance parameters are. Fundamentally we've got extremely good people doing the important jobs everywhere in the factory.

"So we have the skills, we have the people and I think the reason our performance is stronger this year is because every single element is improving; not just some elements but every element. We're finding hundredths of a second every corner and every lap - and that is what is making the difference."

Another positive factor from the 2008 season has been the performance of drivers Timo Glock and Jarno Trulli. The pair have proved to be a perfect combination of youth and experience, pushing each other on track while co-operating closely off it to improve the TF108.
