A GMC engineer explains why the GMC 3.0L Duramax Diesel is so good

We're in Jackson, WY with the 2020 GMC Sierra 1500 Diesel. It's GMC's half-ton pickup with terrific fuel economy. If you use your truck as an everyday commuter vehicle - or even just live out in the country and drive long distances, it's definitely worth a look. Wyoming is truck country, so we're right at home.
Joining Jordan is Tim Herrick, GM's executive chief engineer for Chevrolet and GMC full-size pickups, including the GMC Sierra, Sierra HD, Chevy Silverado and Silverado HD. We talk trucks, engines, guns and more.
