A real off-road vehicle should have an even weight distribution on the axles, with correct tires inflated to the correct pressure, four-wheel drive, high engine power indicator. In addition to these basic requirements, many other modifications are made, which make it easier to move the car in difficult conditions and off-road. For a long trip into an unknown area, you should always choose several cars. If one of them gets stuck, the other can pull it out. High-lift truck or van, with large wheels and long wheelbase, can be used to transport expedition equipment. On the other hand, the other four-wheel drive off-road vehicles are perfect for transporting the members of the expedition.
Modern all-terrain vehicles with four-wheel drive equipped with high-power engines, although they can cross almost any terrain, they are not suitable for long trips, because they have too much fuel consumption. Gasoline engines are lighter, cheaper and more powerful than diesel engines. However, large diesel engines can develop high power in low gears, which matters when driving slowly over rough terrain. Besides, diesel fuel is usually much cheaper than gasoline. The long wheelbase increases the loading area of the vehicle, but such a car is easier to bury in the marshy ground or hangs on bumps. All this must be taken into account when deciding on a specific vehicle.
The perfect vehicle
There are many different types of off-road vehicles. An ideal car should have all the features listed below.
Without a four-wheel drive, it is difficult to navigate the marshy and bumpy off-road. Eventually, if the car does not have four-wheel drive, should be front-wheel drive, not the rear, so that if he gets stuck in a quagmire, he can be pulled out of the mud.
Gasoline engines are lighter, cheaper and usually more powerful than diesel engines. The latter, however, develop high power at low speeds and are usually more durable than gasoline engines. Besides, diesel in many countries is much cheaper than gasoline.
For a long journey you need to take a few spare wheels. You should think carefully, where to put them. Admittedly, hanging them on the rear door or the roof is convenient and saves space inside, but there is a risk of damage to the wheels or their theft.
Facilitates loading and unloading of luggage; allows you to quickly climb onto the roof of the car in case of danger. You can also observe the area from the roof, take photos, or to rest away from the sand heated by the sun.
When it is attached to the roof, it should be tall and strong, so that it can be loaded with large and bulky luggage. Its construction must enable securing the goods with the rope. Luggage must be packed well, for example, in chests.
Radials work best in off-road areas, however, be careful, so as not to damage their sides. Before driving into the sand, it is recommended that you deflate the tires some air, and after reaching the beaten road, refilling.
Adequate distance between the car's chassis and the ground allows driving on bumpy roads and bogs. If the car is low slung, can easily get stuck on the axles, and when there are bumps in the road – the chassis is not difficult to damage.
