What do 4x4 and 4WD mean in cars?
Well, truthfully, a lot of people use the terms interchangeably. But that doesn’t mean they actually mean the same thing. 4×4 and 4WD both mean that power is sent to four wheels to control the vehicle, but it’s a little more complex than that. All 4×4 vehicles have 4WD, but not all 4WD vehicles are 4x4s.
Which is better 4WD or AWD?
It all depends on the type of driving situations which you most frequently plan to encounter and how you plan to use your vehicle. In general, 4WD is preferred for serious, heavy-duty off-roading situations, whereas AWD is excellent for maximizing performance all around but not necessarily off-road.

What is the difference between 4x4 auto and 4x4 high?
The ast majority of newer 4×4 systems have settings for “4-High' and “4-Low,” while the “Auto” setting operates as a default setting. So, when the situation calls for better traction… Use “4-High” when… you are needing slightly more traction than normal, but can still drive at a reasonably high speed.
Should I keep my 4WD on auto?
If you've got a vehicle that offers two-wheel drive or 4-wheel-drive auto, then most of the time you may as well use the 4WD Auto setting. It's fine for dry pavement, so the only advantage of running in 2WD would be some fractional fuel economy benefit—or saving wear on the front-drive system.
How fast can you drive in Auto 4WD?

What is a transfer clutch?
The transfer clutch is modulated to transfer torque to the second axle when needed. This can be triggered either by passive means such as wheel slip or by active control systems that use hydraulics or electronics. The automatic four-wheel-drive mode activates when the system needs to split torque between the axles.

What is an AWD car?
In an AWD car on the other hand, the system allows the engine to send more power to the axle or wheel that are not slipping, meaning that they can travel at different speeds. For this reason, many modern all-wheel drive systems are often referred to as electronic all-wheel drive. This means that an all-wheel drive car can maintain traction with all four wheels around corners and at higher speeds than a traditional 4x4 system.
Is AWD always in AWD mode?
Whereas AWD cars are always in AWD mode, a four-wheel drive vehicle usually has an on-demand system that requires the driver to engage the four-wheel drive system. When not in four-wheel drive, the vehicle stays in two-wheel drive mode (usually rear-wheel drive for a truck or SUV).

How fast can you shift a 4 wheel drive?
These systems typically have a speed limit at which you can engage the system; typically it's under 60 mph. OHVs that use an electronic actuator (like a push-button vs a shift lever) will only allow shifting to 4WD-Hi while under the rated speed, so pushing the button will not attempt to engage 4WD.
What is an all wheel drive car?
An all-wheel-drive is a full-time single-speed 4WD system that will supply power to all four wheels. Each system has a different front-to-rear power delivery ratio.

What is the difference between 4WD and 2WD?
The video clearly shows a major difference in traction and acceleration speed between 4WD auto and 2-wheel drive mode. In 2-wheel drive mode, the SUV could barely gain any traction from pull-off and struggled to get to the third pole. Severe fishtailing was also experienced when accelerating hard in 2H mode on the snow. In 4WD-Auto the vehicle was much more manageable and covered the distance quicker by a good few seconds. There was a slight lag on pull-off as the system engaged.
How does a Non-Permanent 4-Wheel Drive system differ?
Below is an extract from an article you can read here explaining the difference between Permanent 4WD and part-time 4WD.
What is permanent AWD?
The traditional permanent AWD makes use of a viscous coupling to compensate for rotational speeds when turning. The semi-permanent AWD system found on a Honda CRV uses an electric motor to engage the AWD system once traction is lost. The Subaru Forester uses a set of plates submerged in the thick fluid inside the transfer case to maintain traction on all 4 wheels. All very interesting designs with each having its pros and cons.
How to get front and rear wheels back in sync?
This is usually achieved by temporarily “connecting” the front and rear drive-shafts. This is a temporary connection and once the computer recognizes that traction has been regained and the front and rear wheels rotational speeds are back in sync it will disengage and revert back to either front or rear-wheel-drive mode.
How does a 4 wheel drive transfer case work?
Once the sensors detect that there is a difference in rotational speed, usually when traction is lost, one or more wheels will spin faster, it immediately engages 4-Wheel Drive. This is achieved in a matter of split seconds and is hardly noticeable to the driver.
When traction is regained, do you need to revert to 2 wheel drive?
When traction is regained you will need to revert to 2-wheel drive mode immediately to avoid drivetrain binding. You can read more about drivetrain binding cause and effects here. Alternatively, you could just leave your vehicle in 4-wheel drive Auto mode.
What is 4 wheel drive?
Four-wheel-drive systems send power equally to all four wheels, using a transfer case to split the power between the two axles. This is great for off-roading, as all the wheels are spinning at the same rate so you can keep traction through tough conditions, but it’s not so good for driving on-road. Unless the four-wheel-drive system is ‘selectable’ (which we’ll explain later on), driving a 4x4 on the road tends not to be a pleasant experience. Like low-powered city cars on a motorway, asphalt roads are not a 4x4’s comfort zone.
Why do some manufacturers have advanced traction control systems instead of a full-blown all wheel drive system?
Some manufacturers have decided to incorporate advanced traction control systems instead of including a full-blown all-wheel-drive system - often because their customers won’t take the cars off the beaten path.
What electric cars have electric motors?
Powerful electric cars like the Tesla Model S have an electric motor on each axle. While the two axles aren’t connected mechanically, a motor powers each set of wheels. The lack of a mechanical connection also improves interior space and rear foot room, as there’s no need for a bulky transmission tunnel. Some hybrids like the Volvo XC90 T8 Twin Engine use the engine to power one set of wheels and the electric motor to power the other, meaning the car can be front-, rear- or all-wheel drive depending on what’s being used.
Is a performance car rear wheel drive?
Performance cars have traditionally been rear-wheel drive, but more and more are switching to all-wheel drive. Many modern fast cars are hugely powerful, and four wheels are often better at controlling the power than two. It also makes them easier to drive in the wet.
Is a 4 wheel drive a 4 wheel drive?

Can you take an all wheel drive sports car up a mountain pass?
Each system offers slightly different characteristics and have different purposes; you wouldn’t take an all-wheel-drive sports car up a mountain pass, for example. Having power sent to all four wheels used to be the preserve of off-roaders, but now there are cars of all shapes and sizes that can be had with all-wheel-drive.
