Yes. I've had several vehicles with full time AWD but never 4x4.
hey now...you are beginning to learn some of the basic differences between AWD and 4WD.
Differentials and what they do are key in understanding the differences.
The terms all-wheel drive and four-wheel drive aren't interchangeable. Here's why.
Good explanation a few posts in:
Four-wheel drive and all-wheel drive are similar, but not identical, and the difference between the two configurations dictates how far off-road you can drive.
from the last link:
Let’s start with four-wheel drive. Displayed often as 4WD, and sometimes referred to as four-by-four or 4×4, this system’s main distinction is that it’s typically used on vehicles designed and built to handle the unpaved wilderness. This includes rugged trucks and SUVs such as the Jeep Wrangler, Mercedes-Benz G-Class, and the Toyota Land Cruiser.
In a nutshell, it’s a system that sends power to all four wheels equally and without vectoring (controlling the division of power delivery between the wheels or axles), meaning each wheel will spin at the same constant rate as all the others.
Power flows from the engine, through the transmission, and normally into a device known as a transfer case that divides it between the front and rear axles.
The equal split of power is great for maneuvering through tough and low-traction situations, but it isn’t very friendly on the pavement. Driving a four-wheel drive car on solid ground can make simple actions like turning around in a tight street very difficult, because the wheels are no longer in sync.
Imagine yourself doing a u-turn. In a four-wheel drive car, the inside wheel has to turn more slowly than the outside wheel, which is covering more ground.
You might hear a rubbing noise or feel the car hopping when you approach full lock. This is why most 4WD systems are part-time systems that can be disabled.
so the tighter the turn, the greater difference in speed between two wheels trying to turn at the same speed...you see how that can be a problem
