Rumble in the Rockies: Silverado HD vs. Super Duty

With the proven Duramax Diesel and the brawny Allison Transmission, the new Silverado HD beats the competition in the field. Diesel Power Magazine and Pickuptrucks.com recently tested the Ford Super Duty with their new diesel and transmission against Silverado HD with the proven Duramax and Allison. Named the “Rumble in the Rockies” the one sided results crowned Chevy Silverado HD, King of the Mountain.

The magazine took both 1-ton Chevrolet and Ford pickups, hooked them to trailers with 18,900-pound loads and accelerated up I-70 in Colorado. Even though the horsepower and torque ratings are similar, in a real word setting the results weren’t even close.

Acceleration: “the Silverado made it through the quarter-mile more than 2 seconds quicker, achieved a top speed that was nearly 10 mph faster, and finished the entire climb more than 2 minutes ahead of the Ford. The Duramax performed significantly better at 11,000 feet of elevation as well pulling the 18,900 lb load at 47 mph, while the Ford slowed to 35 mph. Acceleration Test Winner: Chevrolet Silverado.”

The article continues, “The exhaust brake test brought out similar success for the Duramax and Allison combination. As we began our downhill run, the Ford descended the western slope well but required an average of 14 application’s of the truck’s brake pedal to hold the vehicle speed between 50-60 mph. Going downhill in the Chevy, the driver had far less work to do…. the Chevy only required 1 brake application for the entire 8-mile downhill run. While the difference in hillclimbing between the Chevy and Ford is impressive, the exhaust braking advantage of Silverado is staggering. Exhaust Brake Test Winner: Chevy Silverado HD.”
