Front-drive and rear-drive are two common forms of driving in cars, and many people have a preconceived impression of the rear-drive that the rear-drive must be advanced, and it must be more advanced than the front-drive car. In today's article, we will talk in detail about the difference between front-drive and rear-drive vehicles.
The difference between the structure of the front drive and the rear drive, as the name suggests, is driven by the front wheel, the engine directly outputs the power to the front wheel to drive the car forward; the rear drive is driven by the rear wheel, according to the position of the engine, it can be divided into three types: front rear drive, middle rear drive and rear drive. In the eyes of many people, the front drive must be more advanced than the front drive, in fact, it is not always the case, these two driving methods actually have their own advantages and disadvantages, can not be generalized.
First, cost and economy In terms of cost and economy, the front-drive car is obviously better, not only in terms of structure, it reduces the drive shaft, rear drive shaft and rear gearbox transmission system than the rear-drive car, reducing the production cost. And because the transmission differentials are concentrated in one housing, the accessories are concentrated and less, and the power transmission is more direct, so the transmission efficiency is higher and the fuel economy is better. Second, the climbing performance is like we push a heavy object uphill, pulling uphill is more labor-saving than pushing uphill. In terms of climbing performance, the front drive car is better, and the heavier the drive shaft, the stronger the driving force can be displayed.
Third, the interior space of the front-drive car is better in the rear seating space, because the drive shaft of the rear-drive car usually occupies a certain amount of chassis space, forming a bulge in the middle of the rear seat, and many front-drive vehicles can achieve a full flat rear floor. Fourth, power and handling control can be said to be a major advantage of the rear-drive car. The front-drive car is first of all the drive mechanism concentrated in the front row, so the weight is concentrated in the front of the car, it is difficult to achieve a 50:50 ratio, and the back-drive car like the BMW 3 Series is easier to achieve a balanced weight ratio before and after, bringing better extreme handling.
Then there is the fact that the front wheel of the front drive car must be both turning and responsible for power transmission, so it is easy to produce a pusher situation. The front wheels of the rear-drive car only need to focus on the work of steering, so the steering is more agile and the handling is better. However, when encountering rain and snow weather, due to the wet and slippery road, it is more likely to oversteer, that is, the phenomenon of tail flicking, many racers will use the tail flick of the rear drive car to achieve better cornering, which is also an important reason why many performance cars are more inclined to the rear car.
In fact, for ordinary people, daily driving does not need to buy a rear-drive car, because the front-drive car can bring you better interior space, better fuel economy, lower price and better climbing performance, but if you are pursuing driving and want to experience the fun of extreme control, you can consider buying a rear-drive car.
