And Then There Was One...
When it came time to pick a victor for our shootout, we debated that there was no clear-cut winner, but after verbally assaulting each pro and con, one truck did emerge as the winner. Pound for pound, the Duramax/Allison combo was our pick for best powertrain, claiming the top spot in performance, delivering great fuel economy, and bringing with it a proven track record. An added benefit is its 5-year/100,000-mile warranty that gives added peace of mind for the extra $8,395 you have to shell out for the engine/transmission combo. As for the gas powertrains, the 6.0L Vortec in the GMC also shined. The Ford's 6.2L seemed strong, and was our favorite of the gas engines initially, but it didn't perform as well as its numbers would have indicated. Perhaps it was a victim of our high expectations, but for a completely new engine with higher power and torque ratings, we couldn't help but be a little disappointed when the smaller 6.0L beat it in several categories.

With those accolades said, the two drivers that had spent the most time towing were impressed by the Power Stroke's strong locomotive pulling power, linear brakes, smooth steering, and intuitive transmission that brought the truck and trailer to a reassuring halt. However, even after the performance data showed that the GMC towed the quickest, the confidence of pulling with the Power Stroke Super Duty, combined with its extra size and commanding stance, earned it the win. We were only able to scratch the surface on the abilities of the SYNC system, but we felt it would prove to be even more useful as time went on and using it became second nature. For road trips and long-haul driving with a cab full of passengers, the extra cab volume would also give the Ford an edge. Congrats to the engineers of Ford for pushing the limits of a 3/4-ton truck and developing an incredible machine that won our 2011 HD Truck of the Year.
