This initially established that a rear toelink (trackrod) gave way causing Timo to lose control of the car, but confirmed that there were no exceptional circumstances before or during the incidentin the German Grand Prix.
Further investigation has established that damagesustained in the British Grand Prix two weeks earlier was the cause.During that race Timosuffered several incidents.
As is normal practice, some parts from the British Grand Prix were carried over to Hockenheim, including most of therear right suspension. Although the parts were subjected to the normal test and screening process following the Silverstone race and passed fit for use at Hockenheim, it has become apparent that it did not identify an issue which subsequently led to the incident at Hockenheim.
As a result of this investigation, Toyota Motorsport has revised its inspection processes to include such cases and is extremely confident there will be no repeat.
