In Parts 1 and 2 of his 2007 Heavy Duty Shootout, Mike Levine and his cohorts from Pickuptruck.com compared the acceleration of gas three-quarter ton and diesel one-ton pickups from Dodge, Chevy/GMC and Ford on flat surfaces, both unloaded and loaded with 10,500-lb trailers. For the third and final report, however, Levine introduced grades of 7% and 15% to the equation.
The results were surprising, and really had the most influence on Pickuptruck.com's final conclusions. We won't spoil the dramatic tail of each hill climb at Ford's Michigan Proving Grounds, but the 2007 Ford F-250 with its 6.8L Triton V10 was particularly impressive in the gasser category, and as anyone who has driven one would expect, the 2007 Chevy Silverado 3500 and its 6.6L Duramax diesel/6-speed transmission combo proved overly dominant among the oil burners. That said, the conclusions are only half the story, as Pickuptruck.com follows each truck through every gear as they climb their grades. These rigorous tests brought every truck's weakness, which were glaring in some cases, as well as their strengths.
