4 wheel drive

Too Afraid to Ask

4WD means the car can send power to all four wheels at once, which helps it grip better on bad roads like mud or snow.

Technical Definition

4‑wheel drive (4WD) is a drivetrain configuration that sends power to all four wheels simultaneously, improving traction on uneven or slippery surfaces. It is distinct from 2‑wheel drive (either front or rear) and from all‑wheel drive systems that are typically electronically controlled.
