What do 4×2, 6×4 and 8×4 mean?
Drive layouts explained: what the numbers tell you, and what they do not.
What do the two numbers mean?
Choose a formula. The driven axles appear in blue.

The formula counts wheel positions, not axles. Twin tyres at one end still count as one position.
Two numbers, two meanings
The first number describes wheel positions; the second describes driven positions. Twin tyres at one position still count as one position in this notation.
Simple examples
A 4×2 normally has two axles, with one driven. A 6×4 has three axles, with two driven. An 8×4 has four axles, with two driven. Other arrangements and steering options also exist.
What the notation cannot tell you
A 6×4 label does not by itself establish payload, body volume, power or suitability for a particular route. Those questions require the complete configuration.
Compare the complete variant
Consider the drive layout alongside the load, route, chassis and body information. Discuss your actual task with a specialist, and do not infer the exact layout from a photograph alone.
