2020 Silverado Duramax Engine Claims 33mpg!

The next Gen 3.0L Duramax is built to save.

Chevy released some info on their next generation truck engine today. It appears the Corvette re-designing giant is really trying to “Find new roads” as their slogan would suggest. The new 3.0L Duramax turbo-diesel will be the first diesel available on the 1500 platform, and also the first 6 cylinder variant. Tim Herrick, Chevy’s executive chief engineer has stated “The engine utilizes state-of-the-art technologies to optimize every drop of fuel, and takes advantage of architectural changes to make Silverado larger, lighter and more aerodynamic than before. The resulting combination offers all of the performance, refinement and capability customers want in a full-size truck, with highway fuel efficiency you would expect from a family sedan.” A lofty claim especially while also boasting 460lb/ft of torque and a 9300lb towing capacity.

We’ve been outfitting Silverados with rims and tires since we started this business 7 years ago. We love the versatility of the platform, be it for your usual pickup business life, or if you want a Lifted and Beefy Mega Monster! The new one’s got some great styling, which you can see in the gallery below, but before we get into it here’s a quick listing from the Chevy press release about some of the primary features of the new Duramax.

  • The inline-six engine provides an inherently balanced configuration for low noise and vibration characteristics. It features an aluminum block for weight reduction, an 84mm x 90mm bore and stroke, dual-overhead camshafts and four valves per cylinder.
  • A new active thermal management system warms up propulsion components more quickly for more efficient operation.
  • The exhaust brake, which is available in tow-haul mode, can provide additional driver confidence when towing, especially when going downhill.
  • The driver-selectable stop/start technology enhances fuel economy by shutting off the engine at stoplights and certain other stop-and-go situations, helping save fuel. The engine automatically restarts when the driver takes his or her foot off the brake.
  • The 3.0L Duramax is exclusively paired with a Hydra-Matic 10L80 10-speed automatic transmission, featuring smaller gear steps and an overall larger ratio spread to enable peak efficiency. Intelligent controls adjust to the driver’s needs for smooth operation and aggressive response.

A Ten Speed! They’re really hoping that the 1500 can take over some jobs normally reserved for the much larger, gas-guzzling 2500 series and above. Suspicions around the NewsDesk are that this will be the priciest engine option for the Silverado, other engine options listed by the giant are;

  • The most advanced V-8s in the brand’s history and updated versions of Chevrolet’s proven 5.3L and 6.2L engines equipped with industry-first Dynamic Fuel Management featuring 17 different modes of cylinder deactivation. The available 6.2L RST achieves class-leading light duty towing capability of 13,400 pounds.
  • An all-new, advanced 2.7L Turbo engine that replaces the 4.3L V-6 as the standard engine on the high-volume Silverado LT and new Silverado RST.
  • Proven 4.3L V-6 and 5.3L V-8 engines deliver full-size truck capability and performance for the most affordable trucks in the Silverado lineup.

Deliveries are expected to begin this fall, so now take a look at the new face of Chevy trucks. (Looks like the gallery might not be clickable right now, so to see them large Right-click and open images in a new tab)
