What does ff mean? Musical terminology.

The Ff in the car is the front-wheel drive of the front engine, and most family cars adopt this layout.

There are many cars with front engines, and the family car adopts the layout of front drive. Due to the low cost of this layout, the space of the passenger compartment is expanded.

Front-engine front-wheel drive automobile engines are mostly horizontal, and the transmission efficiency of this driving mode is relatively high.

The automobile gearbox with transverse engine is also transverse, and the power output by the engine will be directly transmitted to the gearbox, and then to the half shaft through the main reducer and differential, and the half shaft will then transmit the power to the wheels.

The power transmission of this path does not need to change the direction of power transmission, so the transmission efficiency is higher.

If it is rear-wheel drive, the power needs to be changed by 90 degrees to be transmitted to the rear wheel, so the transmission efficiency of rear-wheel drive is not as high as that of front-wheel drive.

However, the front drive also has disadvantages. Most of the weight of this kind of vehicle is pressed on the front of the vehicle, so the front drive vehicle is easy to understeer when turning quickly.

In addition, when going to the track, the front wheel drive can't take the oil bend, which will make the front wheel break through the grip limit, so the full speed of the front wheel drive is not as fast as that of the rear wheel drive.

To put it bluntly, the predecessor is a special layout of the family car.
