We ran each pickup through a battery of instrumented testing, which started with checking their weight (full fuel, no driver) before testing 0 - 60 mph acceleration, 60 - 0 mph braking, quarter - mile
elapsed time, 0 - 60 mph with payload (500 pounds for the midsize trucks, 1,000 for the 1/2 - tons, and 1,500 for the HDs), 60 - 0 mph braking with payload, and 0 - 60 mph acceleration with a trailer (loaded to 75 percent of each truck's
maximum towing capacity).
