1. The drive mode Glossary
drive mode, the engine means a form of arrangement and the number of drive wheels, position. Into the rear-drive (FR), pre-precursor (FF), the rear drive (RR), rear center drive (MR), four-wheel drive (WD)
2. After pre- the basic drive description
That is front-engine, rear-drive (FR for short), is a form of most conventional drive. Its advantages are: their duties front and rear wheels, steering and drive are separated, thus good high speed stability, climbing ability of the vehicle. A disadvantage of such a drive is: because of the need to transmit power from the rear wheel of the vehicle engine through the first shaft, the intermediate drive has a raised floor inside, and affecting the interior space arrangement, also increases the weight of the vehicle , more than a part of the drive shaft also increases power consumption.
3. The basic introduction of FF
i.e., front engine, front wheel drive (referred to as the FF), which pre-precursor Volkswagen Beetle car of a car (including mini, economy car) is very popular on the drive type. Its advantages are: simple mechanical structure, good heat engine conditions, a large interior space, easy arrangement, reduce vehicle weight, more cost fuel, maintenance is also very convenient. Its disadvantages are: since the steering wheel and to assume working and driving, high-speed stability is poor, the uphill drive wheel slippery, easy to roll high-speed downhill.
4. rear center drive substantially description
i.e. mid-engine, rear-wheel drive (referred to as the MR). The rear center drive car type is most Pagani-Zonda sports car and Formula employed. Advantage is that the steering stability and ride comfort is better, the engine has a high transmission efficiency, the steering wheel maneuverability, good mobility. The disadvantage is that occupies part of the space and the luggage compartment, the engine sound insulation and heat insulation poor ride quality decreased.
5. When a basic introduction to rear drive
i.e. rear engine, rear wheel drive (referred to as the RR). The advantage is the vehicle’s front and rear weight ratio close to perfection, but also take into account the advantages of the rear-drive, front-drive after drive but do not have that kind of loss.
6. The four-wheel drive basic introduction
also known as all-wheel drive, front and rear wheels means the car has power. Advantages are: power balance. Disadvantages are: increased weight, higher fuel consumption, maintenance is more complex.
