Toyota was the first Formula One team to officially launch its 2005 challenger, the TF105 being revealed in Barcelona on January 8th. Toyota's three years in F1 have not exactly been stellar but with new drivers Ralf Schumacher and Jarno Trulli, the team is looking to forge ahead.

"Our ultimate goal is to win in F1," said team principal Tsutomu Tomita. "But we know it takes time. Our target with the TF105 is to make an important step on our way to victory."

The TF105 is the first car to be overseen by technical director Mike Gascoyne, who joined Toyota from Renault in 2004. He and Luca Marmorini are responsible for adapting to the new regulations for 2005.

"As soon as we began to get an indication of the likely regulation changes for 2005 we started to set our targets accordingly," said Gascoyne. "We compromised the development of our TF104B car in the final races of last season in order to try and gain a competitive advantage in 2005."

Marmorini added: "We have enjoyed quite a smooth transition to the new engine rules. We started at a very early stage to develop an engine that was increasingly reliable. During 2004, we began to improve the reliability of specific parts in the engine, and in fact we already used some of these parts in the RVX-04 model."

"Creating an engine to last somewhere in the region of 1,500 kilometres was an enjoyable and interesting technical challenge. I am confident that the RVX-05 will reflect our excellent in-house technical capabilities."

Toyota Motorsport President John Howett hopes that the new rules will provide the hoped for financial reductions. "All teams have been willing to make compromises in order to assist the future of our sport," he said.

"I hope the changes that have been implemented for 2005 deliver the intended cost reductions, the anticipated improvement in racing and a real increase in value for the spectators and fans. If not, I hope the legislators will be flexible enough to introduce sensible changes in a smooth and appropriate manner."

Toyota finished eighth overall in the constructors' standings in 2004, something that Tomita is determined to improve upon. "We endured a difficult season in 2004 but I firmly believe we have taken appropriate measures in the factory to turn the seemingly negative into tangible positives in 2005," he commented.

"We have made excellent progress in all departments, most notably in the wind tunnel and machining areas. By striving to continuously improve the accuracy of our testing procedures, we are seeing an ever-improving correlation between the factory and the race track, which will permit us to get the maximum performance out of the car during the race weekend."

"Such progress over a comparatively short period has only been made possible as a result of our initial decision to develop the entire F1 car ourselves under one roof."
