1. Four-wheel drive

Four-wheel drive (4WD) is a system that powers all four wheels of a vehicle at the same time, giving it better grip on difficult surfaces.

  • Better grip on snow, mud, sand, gravel, and off-road terrain.
  • Increased stability when climbing steep or uneven surfaces.
  • 4WD helps in slippery or loose conditions but doesn’t make a vehicle immune to skidding.
