The disadvantages of all front-wheel drive systems are the advantages of rear-wheel drive systems. As some mechanical parts move from the front to the rear of the car, the balance and operability of the car will be greatly improved. When a rear-wheel-drive car accelerates, the traction will not be issued by the front wheels. Therefore, when accelerating and turning, the driver will feel a greater lateral grip and the operating performance will become better. This is why the world's high-speed sports cars and high-performance cars are driven by rear wheels.
Low maintenance costs are also an advantage of rear-wheel drive, although this cost will vary greatly due to differences in structure and model. But if your transmission fails, there is no need to repair the differential for a rear-wheel drive car, but it may be necessary for a front-wheel drive car, because these two components are made together of. However, after decades of development, the reliability of front-wheel drive vehicles has also been greatly developed, and the high maintenance cost may not be a big problem.
The disadvantages of rear-wheel drive are also obvious, such as relatively high assembly and manufacturing costs, more failures, relatively small indoor space, and so on. Now, more cars use independent rear suspension systems, so designers can put the car body closer to the differential and drive shaft when designing, which can increase the indoor space.
Low traction has always been a problem with rear-wheel drive cars, because the load on the rear wheels is relatively small, but now electronic devices have changed this. The traction control system and the electronic body stability system (ESP) allow rear-wheel-drive cars to achieve the same performance as front-wheel-drive cars on wet roads. Improved tire design technology can also improve this defect in rear-wheel drive cars.
