Diesel Engines Delayed Until 2020 Model Year For GM Pickups

General Motors has delayed the introduction of their upcoming 3.0-L Duramax turbodiesel engine until the 2020 model year, according to a new report.

We’ve been patiently waiting for the arrival of the Chevrolet Silverado and GMC Sierra’s Duramax diesel engine since last year. GM said they’d be available for the 2019 model year pickups, but they wouldn’t actually arrive until early 2019. Well, early 2019 has come and gone and we’re barreling straight toward middle-2019 without any Duramax turbodiesel in sight.

Now we know why. According to a memo GM sent to dealers and obtained by Automotive News, the Duramax engine has been delayed to the 2020 model year pickups due to a longer-than-expected emissions certification process.

Things have gotten tense surrounding diesel engines ever since the whole Volkswagen Dieselgate scandal. Since then, Fiat Chrysler and BMW have been caught up in their own smaller scandals that have spooked government regulators into being a little more cautious when it comes to diesel certification.

As a result, things are taking longer than expected to get the Duramax out of certification limbo and into dealer rooms.

In the same memo, GM has also told dealers and customers that orders for the 2019 model year Silverados and Sierras equipped with Duramax engines have all been canceled. Everyone will have to resubmit their orders for the 2020 model year version which was just recently announced. Specific timing on when to submit those orders will be sent out in a subsequent email.

The 3.0-L Duramax engine is the first turbodiesel to arrive on a GM full-size pickup since 1997. The Chevy Colorado and GMC Canyon, both mid-size pickups, have had 2.5-L Duramax turbodiesel available since 2015.

The 2020 model year brings a host of welcome changes to the Silverado and Sierra, including an expanded offering of 6.2-L V8 engines to lower (and more importantly, cheaper) trims. Adaptive cruise control and other advanced driver assistance features will become available for lower trims as well, along with a 10-speed automatic transmission paired with the smaller 5.3-L V8.
