03igup: 2008 Cadillac Srx 4

##title##

In abbreviations such as 4×4, the first figure is normally taken as the total number of wheels and the second is normally taken as the number of powered wheels (the numbers are actually axle-ends to allow for more than one wheel on each end of an axle). 4×2 means a four-wheel vehicle in which engine power is transmitted to only two axle-ends: the front two in front-wheel drive or the rear two in rear-wheel drive.

The term four-wheel drive typically describes larger passenger vehicles that may allow the driver to manually switch (sometimes with an automatic option) between two-wheel drive mode (if available) for streets and four-wheel drive mode for low-traction conditions such as ice, mud, snow, or loose gravel.

All-wheel drive (AWD) is often used to describe a "full time" 4WD that may be used on dry pavement without damaging the differentials, although the term may be abused when marketing a vehicle[non-primary source needed] as there are no specific definitions or guidelines (per the SAE for example) to differentiate these terms. AWD can be used on dry pavement because it employs a center differential, which allows each axle to rotate at a different speed. This eliminates driveline binding, wheel hop, and other driveline issues associated with the use of 4WD on dry pavement. For vehicles with more than four wheels, AWD means all wheels drive the vehicle, to varying degrees of engagement, while 4WD means only four of the wheels drive the vehicle continuously. For example, an AWD vehicle with six wheels is often described as a 6×6, the M35 2½ ton cargo truck being one of the best-known examples (dual wheels on the rear axles are not counted as additional drive wheels).

Because all 4 tires in a full time AWD system are connected by a system of differentials, they are potentially very susceptible to torque reduction when a wheel loses traction. Without sophisticated traction control systems, they would become immobilized when any one of the four tires lost traction. A traditional part time 4WD system does not connect the front and rear via a differential, and therefore does not suffer any front/rear torque reduction—if a front tire loses traction, it does not reduce torque delivered to the rear tires, even without traction control systems.

Part-time 4WD systems are mechanically simpler and cheaper than AWD systems. Also, a part-time 4WD transfer case is usually equipped with a reduction gear setting that provides for higher torque at lower speeds, a vital feature for vehicles that will see much off-road use. In AWD systems a more expensive separate reduction gearbox is usually used. The main drawback of 4WD is that because it lacks a center differential, a part-time 4WD system can only be used in low traction situations where the wheels have the ability to slip as needed.

For added security
For these reasons, full-time AWD is appropriate for improving on-road handling and is seen on cars and car-based crossover SUVs, while traditional part-time 4WD systems without center differentials, or with locking center differentials, are better for heavy-duty use such as off-road or in deep snow and are commonly seen on trucks and truck-based SUVs.

Manufacturers often use these terms interchangeably, and the English word all is obviously equivalent to the word four when referring to a set of four wheels. In typical use, the terms are used as described above, but they are not fixed or legal definitions, and some manufacturers, such as Honda, often use the term "four wheel drive" when referring to systems that include center differentials. These terms are therefore not always very reliable for assessing the features and capabilities of a given drivetrain.
