Auto Review: Sierra 2500 Denali Crew Cab 4X4 is the ultimate contractor tool - Hartford Courant

In the automotive world, trends and needs may change over time, but as long as we build things and need to move heavy items, we'll need trucks. But just as truck buyers always want more power and greater towing and hauling capacity, they've also desired some of the comfort, technology and refinement that has been available in contemporary passenger cars (and lighter-duty trucks). For the 2015 model year, GMC has migrated some of the styling changes and features in 2014 1500 series pickups into the HD truck range, including this week's test vehicle: the Sierra 2500 Denali Crew Cab 4X4. This machine is a sizable beast, with... There are two engines to choose from: a 6-liter Vortex gasoline V8 with 360 horsepower and 380 lb-ft of torque, and a 6. 6-liter Duramax Turbodiesel V8 with 397 horsepower and 765 lb-ft of torque. The six-speed automatic transmission (made by Allison) shifted crisply, and the Denali has a part-time 4WD transfer case with 2WD, 4Hi and 4Low settings. As equipped, this truck could pull a 13,000-lb. conventional trailer and haul a maximum payload of 2,793 lbs. Source: www.courant.com
