Original Site (MotorTrend) :Comparison: 2011 Ford F-250 Super Duty vs 2010 Ram 2500 HD
Diesel connoisseurs have been waiting for this confrontation for ages. The 2010.5 federal emissions regulations essentially forced all three of the 3/4- and one-ton work-truck makers to dig deep and come up with clever ways to provide the most pulling power possible with a much cleaner NOx and particulate emissions rating. The 350-horsepower, 650-pound-foot 6.7-liter Cummins I-6 was updated three years ago and was the first of the HD diesel engines to meet the stricter 2010.5 regulations. Unlike the Cummins, Ford's all-new 6.7-liter, 390-horse, 735-pound-foot V-8 Power Stroke (now built in-house) uses a urea-based aftertreatment emissions system.
