The Birth of Four-wheel Drive 4x4 Documentary

Sit back and watch this 45 minute documentary on 4 wheel driving, a good watch!!!


Taken from the videos description:

Four-wheel drive, 4×4 ("four by four"), 4WD, and AWD is a form of drivetrain most commonly capable of providing power to all wheel ends of a two-axled vehicle simultaneously. It may be full-time or on-demand, and may be linked via a transfer case to provide multiple gear ranges.

A four-wheeled vehicle with power supplied to both axles may be described as "all-wheel drive". However, not all "four-wheel drive" vehicles are "all-wheel drive", as vehicles with more than two axles may also be described as "four-wheel drive" regardless of how many axles, so long as two axles (of two wheel ends apiece) are powered.
