In an exclusive comparison, PickupTrucks.com took a 2011 Ford F-450 King Ranch Super Duty and 2011 GMC Sierra Denali 3500HD and pushed them to their limits on the twisting high altitude roads of the Colorado Rockies. We also tested them head-to-head on a dyno to measure their real-world power ratings a mile above sea level.
First, some background about two of the most luxurious and capable pickups you can buy.
Separate comprehensive road tests are coming for each of these rigs, but for this first test, we visited the folks at ATS Diesel in Denver.
ATS invents, designs, manufactures and distributes diesel truck performance products worldwide for Cummins, Duramax and Power Stroke owners. They also have a one-stop full-service shop for repairs and upgrades.
We put the F-450 and Sierra 3500 on a chassis dynamometer at ATS to measure their power output at the rear wheels.
