Whether you are in the market for a automobile, SUV or pickup, you've likely encounter this question at one point or another: What's the difference between 4WD and AWD? Both will distribute power to all four wheels in the vehicle as opposed to 2WD vehicles that only have front or rear wheel drive. If you live in an area of the country where you'll be driving in mud and snow, the added power of either system is valuable. However, there are nevertheless many people who don’t have a clue what the main difference between the two is.
Despite the fact that they cost more, 4WD and AWD could conserve you
Although a automobile with either system is a lot more costly than a two-wheel drive automobile, you probably won’t discover yourself stranded on the road during bad driving conditions, whether caused by weather or environment. Get more auto loan financing for a safer 4-wheel drive care or get something less: the choice is the buyer’s. You are able to get help choosing between 4WD and AWD by the summary from How Stuff Works below.
Part-time 4WD - throw the switch only when necessary
To answer the difference between 4WD and AWD, we will start with part time 4WD. This is the essential way 4WD is offered; there is a switch that switched between 2WD and 4WD. Excessive mechanical wear can be avoided as long as 4WD is avoided on pavement. Some cars in this class have a 2WD/4WD toggle, and some have added opportunities like 4WD High and 4WD Low (this is the latter of which should only be used in extreme off-road scenarios). Newer part-time 4WD autos allow the driver to shift from 2WD to 4WD High while the vehicle is moving but must be at a complete stop before moving from 2WD to 4WD Low. Before any shift can occur, older part-time 4WD cars have to be stopped. Part time 4WD is for you if you only need 4WD at times. Frequent changes within the driving conditions that would mean a constant switch between 2WD and 4WD are both inconvenient for the driver and add many wear and tear on the drive train.
Full time 4WD is for whenever you want it to keep running
This is 4WD more advanced that will leave it on without giving strain to the vehicle. High and Low settings are available, as well as an automatic 4WD. Shifting from High to Low while in 4WD will require the car be at a complete stop (with most cars). Those drivers who drive under adverse situations more often can avoid the tedious 2WD/4WD switching and go with this full-time 4WD option.
AWD - 4WD without the switch
All Wheel drive will give power to all wheels just as a four wheel drive car but there is never a 2WD drive switch there. AWD locks the cars axles and automatically feeds power to all wheels on slippery roads. Most AWD cars are great for slippery roadway conditions, but are not intended for rugged off-road excursions. However, certain AWD cars like the Dodge Durango and Toyota 4Runner offer a low-gear AWD setting that allows for tougher roads . Much weight isn’t added to the auto by AWD typically and is good for all weather.
4WD or AWD – which is safer?
Both are supposed better than 2WD but How Stuff Works says: that doesn’t mean 4WD and AWD are automatically safer. Drivers should keep in mind that when 4WD and AWD help acceleration, they do not help with cornering and braking. When it comes to stopping on snowy roads, it doesn’t matter what kind of wheel drive your vehicle has. Using the right set of tires, having good brakes and a fine suspension are more important in that case.
