6×4 (drivetrain)

Typical American 6×4 tractor unit

A 6×4 drivetrain (six-by-four) is a vehicle with a drivetrain of three axles delivering power to two wheel ends on two of them.[1] It is a form of four-wheel drive[2] but not one of all-wheel drive.

It is the most common form of drivetrain of semi-tractors[2] and heavy haul fixed-chassis cargo trucks.
