I never understood why folks use the term 4x4....does that mean that folks driving vehicles where power is only going to two wheels are driving 2x4s? Isn’t one of the 4s redundant? If someone has a 4 wheel drive I’m fairly sure it has 4 wheels, no? At what point does a vehicle become a 4x4? I don’t think folks typically call an Audi for example a 4x4....
Just wondering....

Yes, How many wheels are “power driven” out of total wheels. Not axles, but wheels and tires. Example, a military truck that has three axles, eight on the rear two power axles, and two singles on the steer axle that are also power driven would be considered a 10X10. All ten wheels/tires are power driven as an option. If the front axle was not power driven it would technically be considered as 8X10. Another example, there are two types of 6X6, a two axle with duals in the rear and singles front all power driven. And a three axle with singles all the way around all power driven.
4x4 means the vehicle can be operated in either in 4 wheel drive or 2 wheel drive. AWD is different. WIth AWD there is transfer case that shifts power/torque between front and rear axle automatically.
4x4 simply means 4 powered wheels
like 6 x 6 trucks, with four rear and two front drive wheels
2 wheel drive needs no differentiation...
