General Motors Demonstrates Stiffness of HD Trucks Versus Competition
Tailgate Test Used to Demonstrate Frame Twist on Ramp
We don’t have to tell you the fullsize truck market has become one of the most cutthroat automotive segments lately, with “best of” claims flying back and forth on a regular basis. To demonstrate its HD trucks are ready for serious work duty, General Motors enlisted independent testing organization AMCI to test its own Chevrolet Silverado HD against a Ford F-250 for torsional stiffness on a ramp test, demonstrating the strength of its bed and frame.
When driven on to the ramp, the Silverado’s frame twisted only a little more than a quarter-inch, or 0.26 inches. The Super Duty frame, on the other hand, twisted 0.94 inches, and the deformation prevented the rear tailgate from being opened. The Silverado’s tailgate, on the other hand, opened and closed normally. GM claims the superior performance in the demonstration is attributable to the Silverado HD’s high-strength steel frame, as well as its roll-formed steel bed, when compared to the more conventional stamped steel. The roll forming process results in a lighter, more durable piece than a conventional steel stamping.
With the introduction of an aluminum-bodied Super Duty in just a few years, you can expect these comparisons and demonstrations to continue to heat up, just as Ram has started with its “Just the Facts” ad campaign comparing the apples-to-apples capability of its Ram HD trucks to the competition.
