Overview

A closeup shows the Duramax Diesel badging on a red 2021 GMC Canyon SLT, a smaller 2021 GMC diesel truck.

GMC is one of the most popular automobile manufacturers in the country. Since its founding in 1911, GMC has built an impressive history and reputation for putting the most reliable and high-performing vehicles on the road. That continues today with the latest lineup of 2021 GMC diesel trucks that include the Canyon, Sierra 1500, and the Sierra Heavy Duty. 

GMC has a rich history of offering the best diesel engines, especially since designing the legendary Duramax diesel engine in the late 1990s to modernize diesel technology and offer only the best of the best under the hood. That powerful and fuel-efficient diesel engine set GMC apart from other leading truck manufacturers. It's also why there's so much praise for GMC's light and heavy-duty diesel engines. For example, the light-duty 3.0-liter Duramax turbodiesel found in the 2021 Sierra 1500 delivers 460 lb-ft of torque while the beefier 6.6-liter Duramax turbodiesel V8 from the 2021 Sierra HD delivers a jaw-dropping 910 lb-ft of torque.

GMC's commitment to excellence not only delivers great power - it also delivers great capability and performance. By modernizing diesel technology, GMC extended the capability of its diesel trucks and provided more torque and more horsepower. This transforms the already impressive lineup of GMC diesel trucks into high-performing workhorses that excel whether they're putting down highway miles or hauling heavy loads. Add in the fact that GMC is also dedicated to offering the utmost in comfort and luxury on its trucks, and it's easy to see why the 2021 GMC diesel truck lineup is the most popular on the road today!
