A 4×4 SUV or car, likewise called four-wheel drive (4WD) or 4-by-4, indicates a system in which a car’s engine powers all 4 wheels uniformly. Wikipedia defines a four-wheel drive, also called 4×4 or 4WD, refers to a two-axled vehicle drivetrain capable of providing torque to all of its wheels simultaneously. It may be full-time or on-demand and is typically linked via a transfer case providing an additional output drive shaft and, in many instances, additional gear ranges.
Four-wheel drive is also often combined with locked differentials for the best off-road efficiency. Without getting too technical, locked differentials merely indicate that the two wheels on the same axle are locked with each other, even if one has traction and the other does not.
History Of 4WDs
In the late 1800s, the world witnessed a breakthrough in the automotive industry. In 1893 the four-wheel drive system was conceptualized by a British Engineer, Bramah Joseph Diplock. This development was to change the destiny of the automotive sector and with it the outlook of people toward cars. Ever since car manufacturers have designed thousands of intelligent 4WDs that rule our streets today. Skip to the 21st Century and we are spoilt for choices. From Land Rover to Suzuki, every manufacturer has a range of 4WDs available.
The world’s first four-wheel-drive car, according to Wikipedia, directly powered by an internal-combustion engine, and the first with a front-engine, four-wheel-drive layout, was the Dutch Spyker 60 H.P., Commissioned for the Paris to Madrid race of 1903, it was presented that year by brothers Jacobus and Hendrik-Jan Spijker of Amsterdam.[16][17] The two-seat sports car featured permanent four-wheel drive and was also the first car equipped with a six-cylinder engine, as well as four-wheel braking. Later used as a hill-climb racer, it is now an exhibit in the Louwman Museum (the former Nationaal Automobile Museum) in the Hague, the Netherlands.[18]
Are 4WDs Better Than RWDs Or AWDs
You might still be asking yourself whether four-wheel drive (4WD) is better than two-wheel drive (2WD), and which is ideal for you. According to engineers at Volkswagen, there is no one-size-fits-all response. Selecting between 4WD, AWD, FWD, or RWD depends on a number of elements. The two crucial questions to ask yourself are these. What do you utilize your vehicle for? What seasonal conditions do you face? Equipped with that said understanding, obtaining one-on-one suggestions from a certified expert is the most effective place to start your journey.
What Are 4WDs Used For
Besides heavy off-roading and adventure sports, 4WDs have industrial uses as well. From being employed in defence to being used in pickup trucks for heavy industries, 4WDs have been of massive help in shaping the world. Here are a few examples of how 4WDs have contributed to this world.
In heavy trucks
Medium-duty and heavy-duty trucks have recently adopted 4×4 drivetrains; 4×4 medium-duty trucks became common after Ford began selling Ford Super Duty trucks. These trucks shared many parts between the light-duty and medium-duty, reducing production costs. The Dana 60 front axle is used on both medium- and light-duty Super Duty trucks. Furthermore, the Big Three share parts between the companies, reducing costs. The Dana S 110 is currently being used for the rear drive, under Ford and Ram’s medium-duty trucks.
In construction equipment
From heavy carriers to pickup trucks, 4WDs play a major role in the construction sector. Volvo introduced the Model 646 four-wheel-drive backhoe loader in 1977.[56] Case Corporation followed suit in the U.S. in 1987.
