four-by-four

Rugged terrain vehicle

A four-by-four is a vehicle with four-wheel drive—all four wheels receive power from the engine rather than just two.

The term comes from the notation 4×4, indicating four wheels total with four driven.

Four-by-fours are typically trucks or SUVs built for off-road capability: We needed a four-by-four to get up the mountain road.

Also written 4x4.
