Body/Chassis Design and Corrosion Protection (All)

What’s the Benefit?

By designing against rust, corrosion and road damage, Honda engineers help ensure many years of reliable performance.

The Feature:

All Honda vehicles utilize unibody construction.

  • The unibody is made of steel stampings robotically welded into strong box sections; the outer-skin panels contribute to the integrity of the unibody.
  • Extensive corrosion protection is built in at the time of manufacture.
  • All body panels are made of rust-resistant, electro-galvanized steel or aluminum alloy.
  • Panels are joined to eliminate traps where water can collect, helping prevent rust.
  • A special chip-resistant paint is applied along the lower body sides to fend off stone damage, and body seams are protected by a sealer that helps keep out dust and moisture.
  • Plastic wheelwell liners, splash guards and rocker panels help protect the underside from chipping.
