What does a car (FR) mean?

FR is the abbreviation of' FrontEngine, RearDrive', and it is one of the most basic materials used to describe the mechanical structure layout of a car. It means "front engine, rear wheel drive", that is, "front and rear drive".

As the name implies, the engine of a car is placed in the front of the car, and the power is transmitted to the rear wheel through the transmission shaft, and then to the ground through the rear wheel. The front wheel of a car has no power and is only used for steering. In the existing car layout, it can be regarded as an older one, mostly used for big cars or sports cars.

Extended data 1, easy to handle. Because some parts move from the front to the back, the front and rear weight distribution is also easy to approach 50: 50, which greatly improves the balance and handling of the car. This is why most sports cars use rear drive.

2. Easy-to-maintain front and rear drive arrangement also makes the engine, clutch, transmission and other assemblies close to the cab, which simplifies the arrangement of the control mechanism and the structure of the steering mechanism and is more convenient for vehicle maintenance and repair.

3. Compared with other two-wheel drive, the front-mounted rear-drive has higher adhesion pressure and better traction when starting, accelerating or climbing on good roads. At the same time, the front and rear drive models also have good handling stability and ride comfort, which is conducive to prolonging the service life of tires.
