This 2011 Chevy Silverado 2500 HD truck features a new and more powerful engine. The V8 with 397 hp provides enough torque (765 lb.-ft) to give this truck 17,800 pounds of maximum towing capability (fifth-wheel tow). It can tow up to 17,000 pounds with the factory installed hitch. This Chevy Duramax diesel has Hill Start Assist, auto grade breaking, trailer sway control, and Intelligent Brake Assist. The V8, with the Allison 1000 six-speed transmission powertrain, is more fuel efficient than previous models by an impressive 11%.That brings the mpg up to almost 19 on the highway when not loaded. It is also fully compatible with B20 biodiesel.
These Chevy diesel trucks can tow in D or Drive position. Under heavy loads it may be necessary to shift to a lower gear. The same is advisable in hilly conditions while towing a heavy load. If the transmission shifts too often, it is best to switch to the Tow/Haul Mode. The Axle Ratio is 3.73 for both trucks, but the maximum trailer weight differs depending on the model. The GCWR (Gross Combination Weight Rating) depends on each model as well. The exact limitations for each model can be found in the owner’s manual.
