Whether you are in the market for a auto, pickup, or SUV, you probable came across this question at one point or one more: What’s the difference between 4WD and AWD? As opposed to the standard front or rear wheel drive of 2WD cars, both distribute power to all four wheels of a standard automobile. 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, many consumers don’t know the main difference between the two.
Despite the fact that they cost a lot more, 4WD and AWD could save 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. The choice is for the buyer: get more automobile loan for the 4-wheel drive’s added security, or get something less. How Stuff Works summary following should help you between 4WD or AWD.
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 basic 4WD setup offered by numerous automobiles; it consists of a switch that alternates between 2WD and full-power 4WD. As long as the 4WD setting is avoided on dry pavement, excessive mechanical wear can be avoided. Some cars in this class have a simple 2WD/4WD toggle, and some have added choices like 4WD High and 4WD Low (the latter of which should only be used in extreme off-road scenarios). Newer part-time 4WD vehicles allow the driver to shift from 2WD to 4WD High when the car 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. If you’ll only be using 4WD occasionally, then part time 4WD is the best choice for you. Frequent changes in the driving conditions that would mean a constant switch between 2WD and 4WD are both inconvenient for the driver and add a lot of wear and tear on the drive train.
Full-time 4WD – when you want to keep it running
This is 4WD more advanced that will leave it on without giving strain to the vehicle. High and Low settings are accessible, also as an automatic 4WD. Most vehicles require you to be completely stopped before it will shift from low to high and back. Drivers who tend to drive under adverse situations more often can stay away from the tedious 2WD/4WD switching and go with this full-time 4WD option.
AWD – 4WD without the switch
All-wheel drive sends power to all wheels of the car in a comparable fashion to four-wheel drive autos, but a 2WD switch is typically not present. If you were on a slippery road, AWD would lock the axels and feed power to all wheels. Generally, AWD will be good for slippery road conditions but never good for off road excursions. Certain AWD autos such as the Dodge Durango and Toyota 4Runner will offer a low-gear AWD setting that allows for tougher roads. AWD typically doesn’t add much weight to the auto and is good for any weather condition.
Which is safer – 4WD or AWD?
Both tend to maximize traction over a 2WD, but How Stuff Works advises: that doesn’t mean 4WD and AWD are automatically safer. Drivers should keep in mind that while 4WD and AWD help acceleration, they don’t help with your own braking. When on wet or snowy roads, it doesn’t matter what kind of drive your wheels have when it comes to stopping. Having fine suspension, using the right set of tires, and having good brakes will matter most then.
