Toyota has developed and confirmed the efficiency of a hybrid system using a continuously variable transmission (CVT) for relatively large vehicles like minivans. The fuel economy is double that of vans of the same class (in the Japan 10-15 test mode), and the system meets the emissions requirements for the U-LEV category. The hybrid system is configured for four-wheel drive. The front drive unit has a gasoline engine and an electric motor that are connected to a power-switching device, the output from which is conveyed to the CVT. The rear drive unit has an electric motor and a reduction gear that are independent of the front unit.

A compact and high-performance five-speed automatic transmission(A350E) has been developed for passenger cars. The development of this transmission has been aimed at improvement in acceleration performance in the low and medium speed range and at smooth acceleration. A five-speed automatic transmission with a simple gear train has been completed by means of the industry's first modern control theory aided shifting technique.
