How 4×4 Cars Can Help You Get Around The Countryside

In a city with 4×4 cars everywhere it’s easy to wonder what they’re doing there. They’re 4x4s so shouldn’t they be out in the country? No because many of them are useless off-road, with so many now city cars that they’ve become known as Chelsea tractors. They’ve stopped being practical vehicles and have become fashion accessories. Out in the countryside low ground clearance will hurt and more chrome on the radiator grill will have everyone silently judging you.

True 4×4 cars are great for getting around in the countryside because they’ve been built for that environment. They’ll have higher ground clearance so you don’t damage the bottom of your car or get beached on an obstacle. A true 4×4 will also have a higher driving position making it easier for you to see obstacles or changes in terrain. They’re also likely to have chunky tires for better grip in off-road conditions. True 4x4s should also have a low range gearbox. This limits speed but gives you greater power which will get you up a hill. Chelsea tractors often lack a low-range gearbox and Top Gear has shown them sliding backwards down a hill. Technology also plays a part as the latest Land Rover has controls which can be altered from the driver’s seat to adjust the car for maximum traction in off-road conditions. The Land Rover is a premium car with a premium cost, but technology always trickles down to lower priced cars over time. Until that happens there are cheaper alternatives that’ll do the job in the countryside.

4×4 cars can cost more to run but they hold their value better than regular road-cars like hatchbacks. More to the point they’ll go well in the countryside and then transfer onto the road, while a Chelsea tractor will get stuck in the mud somewhere.

How does an airflow snorkel protect the engine from elements of sand and water when driving off-road?

Combustion engines need not only fuel to start. Vehicles can’t switch on in a vacuum or inside a room without oxygen. They can however, work in water and in extreme weather conditions where air is filled with dust, sand or other contaminants. Just because it’s possible to drive in these conditions, it does not mean that it’s advisable. The engine and other parts of the vehicle can be seriously damaged if the car wasn’t designed for driving off road.4x4 snorkels

One of the most distinctive visual and technical features of vehicles designed for rugged terrains is the airflow or air intake snorkel, usually accompanied by an exhaust snorkel of similar design. A snorkel usually looks like a long piece of plastic tubing stretching from under the hood and up the side of the vehicle at roof level.

The high positioning enables the car to draw the air needed for combustion from a higher altitude, making it possible for the engine to run even when the car is partially submerged. The higher position of the airflow also helps avoid other contaminants such as dirt, sand or slush that are found closer to the ground.

While driving off road, the wheels can both pick up dry materials and splash mud in the air which can all clog up the supply of air to the engine. Having an airflow snorkel positioned high up on the roof of the vehicle significantly decreases the chance of any particles entering the inside of the engine and causing damage with a majority of dust clouds ans splashes happening at ground level. As intake snorkels are equipped with a filter it doubles up on the performance of the air filter integrated on the engine, preventing the build-up of grime and dirt beneath the hood.

An added benefit is that the air circulating higher up is not only cleaner, but also cooler. As cooler air is richer in oxygen this makes for a more efficient and cleaner fuel burn which results in increased effective engine power.
