This layout is called "mid-engine."

Vehicle in accordance with the general layout of the location of the engine can be divided into front-engine, mid-engine, rear-mounted engine, which under the wheel and can be divided into front-wheel drive, rear-wheel drive and all-wheel drive (for four-wheel motor vehicle is a four wheel drive. We often say that the layout of the car is MR, FF, FR, F4WD, etc. refers to this combination of the two shorthand.

3 kinds of engine position, front-engine, that engine is located in front of the cockpit, the majority of civilian cars are such an arrangement, mid-engine layout is a commonly used high-performance sports car, Ferrari, Bugatti, Pagani and other high-performance sports car is used in this layout, and even F1 is also used in this layout. This arrangement refers to the the engine is located between the cockpit and the rear axle. The final step is the rear engine, the layout, the engine is located behind the rear axle or rear axle, the layout is a Porsche are rear engine, In addition, the bus on the street is also a post - engine layout.

in the home advantage is that the engine can get a better vehicle weight distribution, especially the MR layout, front and rear of the load balancing, speed up the excellent, handling is also very good, is the best handling the layout.

because a car is the heaviest engine, the car can make the most flexible, it would make the smallest moment of inertia of the car Mody, then the best way is to let the engine is located near the center of mass, that is, mid-engine layout .

rear-mounted engine has the advantage of access to a larger rear load, then the rear of the grip on the large, helps to speed up. Porsche the advantage in this, but the shift, unless it is a Porsche kinds of rear-mounted engine to deal with a very seasoned firms are generally not as good as mid-engine.
, but mid-engine and rear-mounted engine and the disadvantages are some exceptions, most notably the mid-engine compresses the cockpit space, so we look at to the ultra-running have only two seats, noise and vibration as compared to front-engine, serious.

The second issue is cooling. because almost no wind area, it needs to run ultra-large air inlet to provide cooling to the engine .

This is a car-driven approach

FF in the former front-engine front-wheel-powered precursor

This type of simple control mechanism, the engine cooling conditions are good. However, the quality of the uphill when the car after the shift, the former driver wheel attached to the quality of reduced wheel easy to slip; downhill braking when the car is due to the quality of forward, front, overloading, high speed roll-over prone behavior. Now, most cars take this type of arrangement.

FR front-engine rear-wheel drive powered by front and rear wheel

This is a traditional layout type. home and abroad, most of the trucks, some cars and some buses are using this type.

MR mid-rear-wheel drive engine in the driver's seat of the is located in the middle of the rear of the body to power the rear wheels

weight distribution is better motion performance is even more prominent

4WD four-wheel drive front engine with the gearbox after the sub-actuators deliver their power to all wheels in a variety of cases can be better motivation
