The center of gravity of a car is an important factor that affects maneuverability, and placing the heaviest part of the engine on the car body will directly affect the control balance of the car.
Our common engine layout in three locations, front, center and rear engines.
Front engine
The biggest advantage of having the engine on the front of the passenger compartment is its ability to provide ample body space.The advantage of the front engine is that it simplifies the structure of the car's transmission and transaxle, especially for the current mainstream front-wheel drive models , The engine will power directly to the front wheel, omitting the long drive shaft, not only reduces the power transmission loss, but also greatly reduces the complexity of the power transmission mechanism and failure rate.
However, this form of layout heavy front, will affect the flexibility of the front steering, handling will decline, so many manufacturers are trying hard to move the engine to the middle, in exchange for better center of gravity distribution.
Predistortional control of the theory is the worst, while the front-rear drive models can accelerate as much as possible to improve handling, and in the taxi or braking, it is still difficult to avoid heavy head.
Middle engine
Most of its applications in pure sports car and super sports car, the engine is usually placed in the driver's seat after the middle of the car when the car turns all parts of the car due to inertia will move to the outside, the engine is the most massive part of the engine Inertia and the body of the force on the car steering in the corner is crucial.Motor in the center of the engine is characterized by the largest inertia in the vehicle body in the center of the body weight distribution can be close to the ideal Balanced state.
This layout, regardless of acceleration or deceleration, the front and rear wheels can get the maximum grip, more importantly, it can greatly improve the vehicle handling, the vehicle's center of gravity is almost the driver's position, turning flexible and easy for the driver to feel Vehicle gesture.
However, this layout has the disadvantage of taking up the middle of the carriage space, usually only two sports cars can use the central engine. In addition, the maintenance is relatively complicated .As the occupants are too close to the engine, so the noise is larger. However, only the pursuit People who control the car's performance will not be more about these, and even some people are more willing to hear the roar of the engine roar.
Rear engine
In general, the most pure rear is the engine is arranged behind the rear axle, the most representative is the bus, rear-engine passenger cars are numbered, the most representative is the Porsche 911, of course, smart is Rear engine.
This extreme approach makes the front of the car very flexible, even if the full brake, the front can leave a relatively high degree of flexibility.
However, due to the excessive flexibility of the front, rear-drive models are difficult to control when cornering, and once the limit is exceeded, the chances of self-help become lower.
Of course, these are not problems for the skilled driver, but rather the pursuit.
