Company says it used a variety of different tests to prove its bed is superior.

Chevrolet is doubling down on claims that the high-strength steel bed in the Silverado is stronger than the stamped aluminum bed in the Ford F-150.

Following the release of controversial videos this morning, the company has revealed its methodology and testing behind the claims.  Chevrolet says it conducted 26 real-world demonstrations and a handful of laboratory tests which showed the Silverado’s bed "consistently outperformed" the competition.

While Chevrolet has a vested interest in proving its truck bed is better, the company purchased 12 pairs of truck beds through retail dealerships and all demonstrations were conducted without bedliners.  The company goes on to say that in the real-world demonstrations, scratches and dents that did not affect the utility of the truck bed were classified as surface damage.  Fractures, ruptures, and holes were considered puncture damage if they could allow small items - such as nails or gravel - to pass through them.

For the lab tests, General Motor's Research and Development Laboratory used a Dynatup 9250HV machine fitted with a 17 pound wedge striker.  Engineers cut 6.3 x 6.3 inch samples of both truck beds and then dropped the striker on the raised rib of each sample.

The tests showed the following:

  • At 20 joules, both samples deformed but remained intact.
  • At 30 joules, the aluminum sample exhibited hairline fracture while the steel sample showed only increased deflection.
  • At 40 joules, the striker punctured the aluminum sample while the steel sample showed increased deflection. To confirm this finding, 20 pairs of samples were tested at the same level, with consistent results.
  • Steel samples were then subjected to progressively higher impact targets with the first pinhole puncture observed at 90 joules.
