Four-Wheel Drive Vehicles
This article will briefly explain to you the concept of four-wheel drive vehicles, and why they are so useful. You will also find some recommended 4x4 cars that you should buy.
All cars are basically divided into two categories, '4x4' vehicles and '4x2' vehicles. The first figure represents the number of wheels on the car (which will always be 4), and the second number represents the number of axle ends that support the wheels. In 4x2 vehicles you have only two axle ends, one for the front set of wheels and one for the rear set. But in 4x4 vehicles, the number of axle ends are equal to the number of wheels, and this gives the car more mobility, and the ability to steer out of rough terrains with relative ease.
In 4-wheel drive vehicles the engine is supplying torque to all the four-wheels simultaneously, and this is what grants the driver greater control over the movement. But the difference between four-wheel drive vehicles and all-wheel drive cars is that, in the 4x4 vehicles the system involved starts functioning at the control of the driver. This happens by pushing a special gear to put the vehicle into 4x4 drive. This is why an all-wheel drive cars list is very different from that of 4x4 cars, since in these cars a 4x4 wheel drive is enabled at all times.
Best 4x4 Drive Vehicles
Today, most car manufacturers have started producing small four-wheel drive cars as well, so this segment is not just restricted to SUV's. Customers have started realizing that this is a feature they do not mind paying extra to possess, and this has resulted in a surge of small 4x4 drive cars as well. Unlike the giant gas-guzzling SUV's that came with 4x4 drives earlier, we now have a number of smaller 4-wheel drive cars with good gas mileage as well. Here are some good options for people looking for such vehicles.
- Mercedes-Benz GLK350 4Matic
- Audi Q5
- Audi S3
- Suzuki SX4 Crossover
- Suzuki Grand Vitara
- Subaru Outback
- Subaru Forester 2010
- Mitsubishi Outlander
- Volvo XC90
- Volvo V50 T5 AWD
- Volkswagen Tiguan
- Chevrolet Equinox
The Concept of Traction
When we talk about such vehicles from a 4-wheel drive cars list, it is important to understand the significance of traction and torque in the mechanism of the car. Torque is the force from the engine that makes the car move, so it is necessary for the torque to be transferred from the engine to as many tires of the vehicle as possible. On the other hand, traction is the amount of contact between the wheels and the ground. Following on from this, the lesser traction there is, the lesser torque is spread to the wheels. This results in the car not moving properly in low traction areas like ice, snow, or heavy mud. (Please note that these are not the real definitions of torque and traction. They have been made simpler for any layman to understand.)
With the help of four-wheel drive cars, the contact between the wheels and the ground is maximized, thus allowing the driver to move more freely. This also involves other variables like the weight of the tire, the amount of friction between the tire and the ground and lastly, the kind of contact between the ground and the tire (static contact or dynamic contact). This is a complex science of mechanics, and it takes a fair amount of study to understand these concepts completely. At the end of the day, this is enough information you need when you are looking for four-wheel drive vehicles with good gas mileage.
With the help of four-wheel drive vehicles, you can drive in uncharted terrain and not encounter many problems with the traction of your vehicle. This is extremely useful car buying information for people who drive on dirt tracks, or for people who drive on snow. With a little bit of research, you can go ahead and pick out the best vehicle for yourself.
