Here’s the new high-output Cummins for 2012 (right), although from the outside you can’t tell any difference from last year’s engine. Horsepower is the same as last year too. The big change is the extra 150 lb-ft of torque—now 800 at 3,000 rpm—which gives you a towing capacity of 22,750 pounds with 4.10:1 gears. According to our testing, we didn’t experience any loss in fuel economy with the new engine and lower gears. The ’11 and ’12 trucks both use the optional 68RFE six-speed automatic transmission. If you decide on ordering a manual transmission, you’ll get the lower-output engine. Sorry.
