Understanding SUV Terminology

If you are looking for a four wheel drive vehicle, you need to understand the terminology used so that dealers do not confuse you with their words. Understanding these words will help you choose the vehicle that best meets your needs.

SUV  Terminology

SUV

The word SUV refers to a sports utility vehicle. These are normally larger vehicles that can hold between five and eight passengers. Most are larger than an automobile but smaller than a van. These vehicles have a variety of features that often allow drivers to both drive them on the highway and also take them off the highway, which is usually called off-roading.

Chassis

The chassis of a vehicle is the base of a vehicle and consists of its internal framework. It also includes parts of the vehicle like the transmission, drive shaft, suspension, differential, and engine.  Manufacturers can tweak these parts so that vehicles perform differently. For instance, when SsangYong created the Rexton diesel 7 seater, they put an ultra-rigid ladder frame chassis on the vehicle so that drivers can control it more easily when they are driving off-road and pulling a trailer.

4 WD

Four wheel drive refers to the fact that all four wheels help to power the vehicle. This feature allows drivers to get through rugged conditions. Around the globe, manufacturers make vehicles with a variety of different styles of four wheel drive. Some vehicles, like the Rexton, have selectable 4 WD allowing drivers to choose when they want to use all four wheels to power the vehicle. When the driver does not choose to use this option, then the vehicle is powered by only two wheels. Not using 4WD is a great option when the driver is on a slippery surface because the rear and front tyres are locked together. Drivers should not use 4WD when driving on dry highways because it will tear up the vehicle.

Transmission

The transmission of the vehicle controls the amount of power that the vehicle has to use. Some vehicles do this automatically. Drivers can decide how much power the vehicle needs with a manual transmission. The transmission is made up of different parts, including the final drive shafts, the differential, the gearbox, and the clutch. Another term that buyers see associated with the transmission is the maker of the transmission. For example, the Mercedes-Benz, five-speed automatic transmission is in the Rexton. The more smoothly the transmission allows the gears to change, the better and the higher the vehicle’s fuel economy.

Transmission

Torque

Vehicles have different amounts of torque. In South Korea, the amount of torque is measured in Newton per metre, often abbreviated Nm. Torque is the amount of twisting force supplied by a drive to the load.  If you are looking to pull a trailer, then you want a vehicle that has a low torque to have the power to pull the trailer. 360Nm of torque will usually let you pull a 2.6 tonne braked trailer.

Choosing the right vehicle can be difficult, but you are well on your way now that you know these common terms.
