Together, these components can also be referred to as the power train or transmission line. Functions: ? Convert engine torque and engine speed ? Transmit torque to the drive wheels Types of drive:There are mainly three types of drive: rear wheel drive, front wheel drive and all-wheel drive.Rearwheel drive: includes front-engine drive, transaxle drive, rear-engine drive, mid-engine drive and under floor-engine drive.Front wheel drive: In case of front drive, the engine is situated either in front of, above or behind the front axle.All-wheel drive: includes permanent all-wheel drive and conventional switchable all-wheel drive.Hybrid drive: In case of a hybrid drive, two different power plants are combined in one vehicle to assume the drive function, e.g. a diesel engine for long-distance driving and an electric motor for emission-free urban driving.
