Hybrids SUV or hybrid sport utility vehicle is high performance vehicle that are compatible to using two distinct sources of power – the electric motor and the gasoline. So, these hybrids SUV provides a fuel efficient source of power.
Actually, hybrid cars can be categorized to ‘strong hybrids’ and ‘milder hybrids.’ The ‘milder’ hybrids are dependent primarily on the gasoline engine. They use a small generator or electric motor 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.
Hybrids SUV Models
Lexus and Toyota are providers of hybrids SUV. 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. Ford Escape Hybrid and Toyota Prius are examples of strong hybrids which have a larger role ascribed for the electric motor.
Features and Functionalities of Hybrid SUVs
The Hybrids SUV’s pathway of energy might be able to be varying to wide extents. This depends upon various conditions and driver’s demands. Usually it is the electric motor that provides most of the momentum while driving at lower speeds despite the engine revving. The smaller motor or generator will absorbed the excessive power from the engine and then routed back to the main motor to be used either for providing the energy for charging the battery pack or to move the car.
Hybrids SUV setup are simple system. No rotating belt is there as in case of standard or conventional Continuously Variable Transmission (CVT). With their planetary gear set, there are simply two electric motors and a gas engine is permanently linked together. 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.
There is a third generator or electric motor in case of the Highlander Hybrid 4WD-i and RX400h – two models of Hybrids SUVs. It is worth noting that the front-wheel-drive Highlanders do not have this motor. These Hybrid SUV models have none of the typical elements present in an all-wheel-drive system, namely, individual drive shafts connecting the front and rear axles and a center differential varying the power split. The independent third generator or electric motor rated for 68 horsepower and 96 lb-ft of torque is instead built into a rear transaxle. It is only in times of need like during hard acceleration or starting on a slippery surface that the rear electric motor comes into play. While moving under force of gravity (coasting) and braking, this rear electric motor acts as a generator. In other circumstances the two models work as front drive SUVs.
