What's the difference between front and rear of a car engine?
The only commercially available car Porsche RR 911 as an example, the official before and after the weight ratio is 39:61, almost equal to a turn FF car, MR car weight ratio is more uniform, the Porsche Boxster 46:54, Ferrari 360 Modena 43:57. Although some car factory like FR cars can do 50:50 car weight ratio, the controls is handy, but from the perspective of acceleration, or head light tail heavy MR and RR are the most favorable for before and after the weight ratio is as small as possible, will adopt a car body design wide narrow tail head and rear wheel the coarse
In actual driving, the wheel idling affects the transmission of power. There are two conditions: starting and bending. FF the driver of the car for the two kinds of the most troublesome, one is watched continuously from the power output of the engine, but the car is going round in circles, and when bending, inner tire crazy turn, but did not want to accelerate the reaction. For the MR and RR of the car, the driver as long as the kick accelerator, the car will be in accordance with your thoughts on flying, and can withstand the power of the engine is much larger than FF car, when you drive a horsepower over 250 FF car, you will feel the car began to get out of control, so the fanatical pursuit of power and the speed of the super sports car, MR and RR is the best choice.
And where are the benefits of using pre - drive? The structure of the pre drive, the engine power is directly transferred to the front wheels, thus eliminating the need for a drive shaft conveying power from front to back, so that the central interior floor would not have a protrusion, increased legroom. And the front engine can be arranged transversely in front, transmission and differential can be connected into one, with respect to a rear wheel drive car, manufacturing technology is relatively simple, and the parts should be less, it can also reduce the manufacturing cost of car.
Front engine, front wheel drive vehicle drive system, that is, what we usually call FF. In addition to some high-performance sports cars, the cars we see on the street are generally pre - engined. Why? Obviously, the engine is placed in the front, you can increase the interior space, to make the ride more comfortable, so as not to pursue high performance supercar like car or SUV this kind of vehicle is the front engine layout.
