Duramax Diesel Engine

Why Is A Duramax Right For Me?

duramax diesel engineWhy choose a diesel over a gasoline engine? Diesels, like the Duramax Diesel turbo-diesel 2.8-liter I-4 offered in the GMC Canyon small pickup truck, and the 6.6-liter turbo-diesel V-8 available in the GMC Sierra HD, offer distinct advantages that may be beneficial in how you plan on using your new truck.

Low-End Torque: Torque is the measure of an engine’s ability to move heavy loads, whether it’s a payload in a pickup box or a heavy trailer attached to the hitch. Having more torque is always a good thing, but having a substantial amount in the lower ranges of the engine’s rev band makes it easier to quickly and confidently launch a loaded truck. That can be quite advantageous when pulling a heavy trailer on a highway on-ramp.

Because of their high cylinder compression and long piston stroke, diesel engines are generally able to produce a substantial amount of low-end torque. Certainly, GMC’s latest Duramax Diesel 6.6-liter V-8, available in the Sierra HD heavy-duty pickup trucks, provides plenty of pulling power. This state-of-the-art diesel engine produces a tremendous 910 lb-ft of torque, with over 90 percent of that power available just over 1500 rpm. Even our smaller Duramax Diesel, the 2.8-liter turbo-diesel four-cylinder available in the GMC Canyon, offers 369 lb-ft of torque at 2000 rpm.

Enhanced Trailering: Diesel trucks often provide higher trailering ratings than comparably-equipped trucks with a gas engine. For instance, a two-wheel drive Canyon crew cab equipped with the 3.6-liter gasoline V-6 has a max trailering rating of 7000 pounds. A comparably-equipped two-wheel drive Canyon crew cab equipped with the available Duramax Diesel 2.8-literI-4, however, has a max trailering rating of 7700 pounds –the highest towing rating of any midsize pickup†.

Exhaust Braking: Both our Duramax Diesel engines are offered with an exhaust brake, which leverages engine compression to help slow the vehicle down and provide the driver with enhanced control, especially on steep hills Using the exhaust brake can slow a truck on long, steep stretches with reduced wear on the conventional brake system.

Improved Efficiency: There’s no better example of a diesel engine’s ability to operate efficiently than the Canyon Diesel. Canyon’s available 2.8-liter turbo-diesel four-cylinder allows it to offer impressive EPA-estimated fuel economy ratings. Two-wheel drive Canyon Diesel models are EPA rated at an impressive 31 mpg highway.
