Diesel engines are commonly used in bigger vehicles like trucks. Sometimes there are specific model diesel engines used in specific model vehicles. When it comes to the Duramax diesel engine, you’ll find it used in virtually all GMC trucks. GMC, of course, stands for General Motors Company.
In 2001, the Duramax diesel engine was introduced to consumers. However, it has been updated numerous times over the years since then. The latest model is a 2018 6.6L V8 turbo diesel engine. People love this engine for its horsepower and 910 lbf⋅ft of torque. If you want to get your speed up quickly after stepping on the accelerator, then make sure the truck you purchase has one of these engines in it.
Certain midsize pickup trucks, such as the GMC Canyon and Chevy Colorado, have a 2.8L Duramax turbo diesel engine. This is a smaller version of the engine and has only 369 lbf⋅ft of torque. But both engines have amazing gas mileage and power. These are the important things that most people are looking for, especially the low gas mileage.
