The electric power train unit is hidden in one unit together with the differential, which lowers the cars weight center and improves the handling. The batteries are of Ni-MH type and are hidden at the back of the car in the area of the boot space and thus slightly decrease its size. But the uncompromised driving experience is worth it. To imagine it, for example at the RX400h model, the combustion V6 engine performance of 155 kW is accompanied by the front electrical engine with the performance of 123 kW and the rear electrical engine with the performance of 50 kW, and thus they offer together imposing 328 kW.
