What is wheel drive system information? When the engine is installed in a car, it is installed in two positions. The first type is the Transverse Engine type that is installed in a 90 degree position according to the direction of the car (the type installed in Ractis, Fit, Vitz, Swift, Demio). The second type is the Longitudinal Engine type. It is installed parallel to the direction of the car (the type installed in Mark II, CROWN).
The layout of the engine and the wheels that will be driven is usually defined in 4 ways. Front Engine Rear Wheel Drive (FRWD). Front Engine Front Wheel Drive (FFWD). Rear Engine Rear Wheel Drive (RRWD). And Four Wheel Drive (4WD).
1. Front Engine Rear Wheel Drive (FRWD) (wheel drive system information)
Front engine rear wheel drive (FRWD) cars use longitudinal engines. The transmission (Gearbox) is in the front, and the rear wheel is connected to the differential through the drive shaft. The advantages of this system are balancing the weight of the whole car. Wide availability of cargo space Even though it is rear-wheel drive, it is in front of the engine so it can get air cooling. Being able to prevent understeer from going to the other side without reaching the side of the turn. When climbing hills, the weight of the car is towards the back, so it is more convenient because the drive train is behind.
Disadvantages are over steering, Because it is rear-wheel drive, the drive shaft is placed under the car’s belly, and when the ground clearance is higher, the CG (center of gravity) is higher, and the car’s stability is not very good. More weight than a front-wheel drive car; Because the car floor is higher, the interior is narrower. Because the car is heavier, it consumes more fuel, and the value of the car is higher due to the engine and drive wheel connection materials.
