What are the advantages and disadvantages of front-engine rear-wheel drive?
2 Answers
Front-engine rear-wheel drive has the advantage of good handling stability; the disadvantage is that it affects fuel economy. The following are the specific advantages and disadvantages of front-engine rear-wheel drive: Advantages of front-engine rear-wheel drive: When starting, accelerating, or climbing on well-paved roads, the load on the drive wheels increases (i.e., the adhesion pressure of the drive wheels increases), and its traction performance is superior to that of front-engine front-wheel drive. The axle load distribution is relatively even, resulting in good handling stability and ride comfort, and it helps extend the service life of the tires. The engine, clutch, and transmission and other assemblies are close to the cab, simplifying the arrangement of the control mechanism. The steering wheels are non-driven wheels, making the steering mechanism simple and easy to maintain. Disadvantages of front-engine rear-wheel drive: The use of a driveshaft device not only increases the weight of the car but also reduces the transmission efficiency of the powertrain, affecting fuel economy. The layout of the longitudinally mounted engine, transmission, and driveshaft and other assemblies reduces the space in the cab, affecting ride comfort; at the same time, the reduction of floor height is also limited. When starting and accelerating on snowy or slippery roads, the rear wheels push the body, which can easily cause fishtailing.

As someone who frequently commutes by car, I've experienced front-engine, rear-wheel-drive vehicles. The advantages are superb handling, even weight distribution, rock-solid stability during turns, and the exhilarating push-back sensation during acceleration. However, there are notable drawbacks, such as higher fuel consumption, especially in urban traffic where fuel burns rapidly as soon as the RPM rises. Rear-wheel drive is more prone to slipping on wet or snowy roads, increasing the risk of wheel spin during starts and adding to the driving burden. Space is another issue—the rear drive shaft causes a noticeable hump in the rear floor, making the middle seat uncomfortable and compromising overall comfort. From a practical daily-use perspective, while the driving experience is thrilling, the fuel efficiency and space limitations make it less suitable for family road trips. Overall, it excels on flat roads but requires extra caution in adverse conditions.
