Vehicles are tagged 4-by-4 for the reason that all of its four wheels are capable of receiving torque from the engine at the same time. This feature enhances the vehicle's performance in terms of traction and stability, especially on a demanding terrain. The term 4-by-4 refers to both the four-wheel-drive (4WD), commonly associated with SUVs and trucks, and the all-wheel drive (AWD), presently associated with most smaller cars and minivans.
Better Overall Performance
In general, 4-by-4 vehicles generate better car performance for off-road driving. For typical 4WD vehicles, like SUVs and trucks, you'll have better traction climbing up a hill or driving on off-road conditions. For newer AWD vehicles, the 4-by-4 system is incorporated to add safety and stability even when driving under harsh conditions.
On top of this, most 4WD vehicles are only a small amount more expensive than standard 2WD vehicles, costing between £650 and £3,250 more depending on the vehicle model and brand.
The four-wheel drive technology can have many variations. 4-by-4 used to pertain only to 4WD vehicles or SUVs and trucks. With the growing number of drivers and increased use of technology, AWD vehicles, such as sedans and minivans, are now equipped with a similar technology. Many of the core features of the 4WD, like traction and stability, are incorporated in today's AWD vehicles.
Many 4WD vehicles come with an automatic switch, that allows an easy transition from 2WD to 4WD, depending on the road conditions and the driver's preference. When the car sensor detects slippage on the front wheels, control is directed to the rear wheels, and vice versa. This gives added stability in any weather or track condition, allowing the driver to focus on the road and let the car do the handling.
