Engine analysis - Toyota RVX-06 20 November 2006
A controversial engine in many ways. In previous seasons the engine has always been a strong point of the Toyota package, but this year it wasn't always so. The TF106 had weaknesses in several areas and the engine was certainly among them. It reportedly lacked top-end power, usually running lower revs than its rivals. The engine block, on the other hand, was one of the lightest - a potential advantage in terms of performance, but a potential risk in terms of reliability. This should not be considered a mistake on the part of engine designer Luca Marmorini, rather a reflection of his compliance with requests from Mike Gascoyne's chassis department to give them more freedom with weight distribution.
