What does ff stand for in car drivetrains?

In car drivetrains, ff stands for front-engine, front-wheel drive. Most family cars use this layout. Some front-engine, front-wheel drive cars have transversely mounted engines, while others have longitudinally mounted engines, such as certain models from Audi and Volkswagen. For transversely mounted engine models, the transmission also needs to be mounted transversely. The advantage of this setup is that it does not encroach on the cabin space, allowing for a larger interior and improved comfort. However, there are also drawbacks. Due to the transverse mounting of the engine and transmission, most of the weight is concentrated at the front of the car, which can negatively affect handling. Front-engine, front-wheel drive cars are prone to understeer during fast cornering. Understeer occurs when the excessive weight at the front causes significant inertia, leading the front wheels to lose traction first. As a result, the car cannot follow the trajectory intended by the driver.
FF drive actually means front-engine, front-wheel drive. Simply put, the engine is mounted at the front of the car and drives the front wheels. This design is the most common; I've driven many FF cars and found they offer high space utilization, with no protruding driveshaft in the rear seats, making them more comfortable to sit in. Car manufacturers choose FF because it's cost-effective, with fewer parts making it easier to produce—models like the Honda Civic use this. In terms of handling, FF cars can experience some pull during turns, not as agile as rear-wheel drive, but they're stable for everyday driving, especially fuel-efficient in city traffic jams. The downside is the front-heavy engine might increase the load, so it's something to watch on long trips. Overall, FF is quite practical, suitable for family daily use, and understanding this can help save money and ensure safety when choosing a car.
In my driving experience, FF stands for Front-engine Front-wheel drive. Driving such cars, like older Toyotas with the engine in the front driving the front wheels, offers stable cornering, especially in rainy and slippery conditions with less skidding. I've driven on mountain roads before, and FF cars are easy to control without spinning, plus they have spacious interiors for luggage. Maintenance is simple with fewer issues, and mechanics are familiar with them, saving money and hassle. The downside is needing extra caution on snow, as they may understeer or 'push'. Many manufacturers use FF because it's affordable and reliable, making it popular in economy models. Understanding FF can enhance driving safety, and beginners should avoid overly aggressive rear-wheel drive cars.
