Toyota's Formula One team has admitted that it will have to review the way it tests components ahead of them appearing on its cars, following the embarrassing demotion of both Timo Glock and Jarno Trulli to the rear of the Australian Grand prix grid.

The pair had originally qualified sixth and eighth respectively and, as part of the so-called 'diffuser three', were expected to have a legitimate shot at a podium finish, if not the win itself, but had their times stripped by the stewards following post-session investigations which revealed that the rear wing on both cars flexed to an excessive degree, thereby increasing downforce.

Unable to defend itself against the finding - and the team was rumoured not to be the only one in the paddock under suspiscion of running with technical irregularities after qualifying - Toyota said that it would 'naturally accept and respect the decision of the race stewards', but vowed to ensure there would be no repeat in future.

"The design has passed our own internal test procedures, which are designed to reproduce twice the proscribed official load tests," an official team statement revealed.

"In light of this decision, it is clear [that] we must review these procedures to ensure there is no repeat of this situation. We will also review our production processes to ensure there is no variation between parts."

The team also revealed that it planned to act swiftly to ensure that its cars would be legal to race in the season-opener on Sunday.

"We intend to modify the components overnight, and we are confident these modifications will not result in any performance drop," it confirmed.

Ironically, Toyota was apparently alone amongst the teams whose diffusers were protested on Thursday in having brought a modified replacement part to run had its original been found illegal.
