There are two models of hybrid SUV according to electric motor used . 'Milder hybrid' and 'strong hybrid'. The ‘milder’ hybrids are dependent primarily on the gas engine. They use a small electric motor/ generator to supplement this. There are also ‘strong’ hybrids in which the electric motor is given a larger role enabling it to propel the car on its own at low speeds.Toyota and Lexus are providers of hybrid SUVs.Honda provides the mild hybrids. These are the ones that rely mainly on the gas engine while using a small electric motor or generator to supplement it. Toyota Prius and Ford Escape Hybrid are examples of strong hybrids which have a larger role ascribed for the electric motor.
The pathway of energy for the Hybrid SUVs can vary to wide extents. This depends upon various conditions and demands of the driver. Usually it is the electric motor that provides most of the momentum while driving at lower speeds despite the engine revving. The excessive power from the engine is absorbed by the smaller motor or generator and then routed back to the main motor to be used either for providing the energy to move the car or for charging the battery pack.
A simple system is involved in the Hybrid SUV setup. No rotating belt is there as in case of conventional Continuously Variable Transmission (CVT). There are simply two electric motors and a gas engine that is permanently linked together using a planetary gear set. The driver can perceive nothing but only a smooth flow of power in spite of the fact that there is a lot of variation in the different modes.
