The rear engine rear wheel drive was widely used in miniature cars because of its compact structure, neither a heavy drive shaft nor a complicated front wheel steering and drive structure. Its drawback is that the rear axle load is large, in terms of handling will have the opposite of FF overturning tendencies, that is, high-speed cornering stability is poor, easy to slip. There are already very few cars that still use RR layout. Porsche 911 is one, and it is easy to flick the handling characteristics is also out of the name.
The mid-engine rear wheel drive engine is placed in the front and rear axle layouts. The biggest advantage is that the axle load is uniform and has a very neutral handling characteristic. The disadvantage is that the engine takes up the space of the cockpit, reducing the space utilization and practicality. So the use of MR are mostly the pursuit of the performance of the sports car.
The advantages of the rear drive: the front and rear wheels of their duties, steering wheel and drive wheel separately, so high-speed stability is good, the vehicle climbing ability, before and after the weight distribution uniform, handling is good. Disadvantages: due to the existence of the drive shaft Inside the floor raised, affecting the interior space and layout, while increasing the weight of the vehicle, more drive shaft, also increased the power loss.
