Feature 4x4 vs. AWD When it comes to traction, it goes without saying that four wheels are better than two. Twice the rubber pulling on the road means more get up and go when you need it. Thanks to technology we have a vast array of different ways to make that equation work for us. With so many options it’s easy to get lost. Let’s take a look at the differences and see if we can better understand the Nissan four wheel drive and all wheel drive systems, how to tell them apart and, most importantly, where to look when something goes wrong. This badge means serious off-roading traction, but what does it actually do for you? 4 | Nissan TechNews As technology advances we have more Both systems seem to have the same meaning, opportunity to give the consumer so much that all four tires put power to the ground. In more of what they want in a vehicle, and even fact many of the same components make each provide some features they never knew they system work. So why have different names? couldn’t live without. Even if it is never used, the It really isn’t a big, complex secret, and security of knowing a truck has four wheel drive there isn’t any hard and fast rule in the actual is an excellent selling point — for safety, for the wording. Generally speaking, four wheel drive beefy appearance, or just for the potential of is an aggressive locking of the drivetrain playing in the mud. for maximum traction that can be applied We have all seen the commercials where an by the driver at will through a gear shift, or all-terrain tire is slinging mud in slow motion electronically with a switch. This is the system as the truck bounces down a forest road or you will have on trucks and SUVs that are construction site. The driver is just grinning as intended to go off road. he knows his truck is the toughest on the trail. All wheel drive, on the other hand, is a passive On the other side of the coin, we can’t system that is either active all the time or is discount how all wheel drive gives the sense activated and deactivated by a sophisticated that the vehicle is secure and glued to the road, computer control system. It is flexible enough giving confidence to a driver in the storm with to provide the appropriate traction for any rocks falling on the road in their path as the driving conditions and still keep fuel mileage as small child sleeps in the back seat. There is no high as possible. This is the safety feature that “fun” here, just a sophisticated car owner that will keep the car moving as the snow falls and made the right choice in the safety feature makes it possible to get those cookies safely to known as all wheel drive. grandma’s house. The big hurdle that has to be overcome in any system having all four tires tied to the drive train is that at some point the driver might want to turn the vehicle. When a car is going in a straight line, barring any difference in tire size, all four axles turn at the same speed. As soon as you turn the steering wheel, all four axles turn at different speeds. In a turn the outside tires travel a longer distance and must rotate faster, while the inside tires rotate slower, the front tires slightly more so than the rear. 4x4 systems drive like a standard two wheel drive, usually rear wheel drive, until the driver decides extra traction is needed, such as in icy conditions. The driver then locks the vehicle into four wheel drive In replacing the old-fashioned transfer case shift without worry of the tires binding due to the lever, this on-dash switch makes changing to four wheel drive, and back again, very easy. The switch difference in speed while turning, since they can is accompanied by an electronic shift actuator on slip as needed to make up the difference. the transfer case. Nissan TechNews August 2018 | 5 4x4 vs. AWD When traction is restored by driving onto a solid, clean road surface, the driver is quickly reminded to shift back into two wheel drive by the binding in the system as all four tires gain traction once again. This binding action is often referred to wind-up. These are the systems you will find in the trucks and taller SUVs like the Frontier, Titan, Xterra, and older Pathfinders. It says AWD on the badging of this 2013 Juke, but All wheel drive is either designed to be what does that really mean, and how does this engaged all the time or is controlled by an on system differ from a regular 4x4? board computer and has no driver controls to turn the system on and off. The system has to automatically compensate for the difference in tire speed and, until recently, that made it necessary for the system to be less aggressive than the 4x4 version.
