Both cars drive all four wheels so in one sense there is no difference except that AWD has become an accepted description for a car that drives all of the wheels, all of the time. These vehicles are predominately truck based platforms with large wheels and off road tyres that combined with a manually selected and a locked 4WD driveline enables the vehicle to venture off-road and negotiate very difficult terrain.
A locked 4WD driveline means that there is direct mechanical link between front and rear axles with no mechanism to allow any difference in the number rotations of the front and rear axles. This means that when the 4x4 vehicle turns a corner because the radius of turn is different for front and rear axles, the tyres on the axle with the smaller radius of turn must be able to slip on a loose slippery ground surface.
If the ground surface is not slippery and the tyres do not slip, then the driveline axles and propeller shaft etc will twist and stress will be induced. This will generally only happen at lower speeds on ground surfaces with no slip. Many manufacturers including Ford, Holden, Isuzu, Mitsubishi and Toyota sell SUVs based on their respective 4x4 utes and all of them are built for off-road adventures.
Alternatively, those very utes they are based on are also quite handy off road. This site will not function correctly without JavaScript enabled. Please enable JavaScript in your browser. We use cookies and other technologies to understand and improve your browsing experience.

Many 4WD vehicles are simply bigger than other vehicles and this can benefit crash performance. Are they fuel efficient? Related reading. If your next new car is a MG, Volkswagen, or Tesla, did you know there is a good chance it will be manufactured in China?
In high-performance vehicles, all-wheel drive helps transfer the engine's torque to the ground while cornering at high speed or when launching from rest with the engine's full oomph. Many all-wheel-drive systems seamlessly shuffle torque between the front and rear tires as needed and automatically switch to two-wheel drive when appropriate to improve fuel economy. All-wheel drive can be used on pavement with no ill effect because it is engineered to enable each tire to rotate at its own speed in turns—inboard tires rotate slower in corners—so all-wheel drive is a better system than four-wheel drive for the average driver seeking bad-weather security.
For this reason, all-wheel drive is what you'll find on most modern SUVs and passenger cars. It's even increasingly offered in pickup trucks, the longtime domain of four-wheel drive. Intended only for use off-road or on extremely slippery surfaces, 4WD is a part-time system, meaning the driver must shift into and out of four-wheel drive by turning a knob, pushing a button, or yanking a lever.
Doing so locks the front and rear driveshafts together, keeping the front and rear axles turning at the same speed. In sand, mud, and snow, this guarantees that, at a minimum, engine torque is always being sent to at least one front and one rear wheel, without relying on computers to predict or detect wheelslip. And that means there's more power being put to the ground in ultraslippery conditions to get you moving and keep you going. But four-wheel drive is not designed to be used on paved roads and is reserved for vehicles with serious off-road capability, like the Jeep Wrangler and Gladiator and pickups such as the Ford F Raptor and Chevrolet Colorado Bison.
The difference between all-wheel drive and four-wheel drive is like the difference between beer and tequila. In a curve, a vehicle's four wheels all rotate at different speeds. You can see this in the tracks left when a vehicle turns through fresh snow as each wheel traces a unique arc with a slightly different length. To allow the front and rear tires to spin at different speeds, all-wheel-drive systems use either a center differential or a clutch-pack coupling between the front and rear axles.
We've covered the complexities and nuances of the common hardware in our overview of all-wheel-drive systems. A four-wheel-drive system locks the front and rear driveshafts together, so that they rotate at the same speed and receive equal amounts of torque. Try driving in a tight circle on dry pavement with four-wheel drive engaged and you'll both feel and hear an unnerving shudder as the driveline binds up. Sometimes the front tires will also hop and chirp.
This binding stresses the driveline and will cause the tires to wear unevenly if four-wheel drive is regularly used on paved roads.
