Just a few months ago, we here at Diesel Army did a full-on test session with a new Silverado 1500. That being said, we loved it! The truck was seriously impressive. As you know, things in this world are a little upside down right now. That being said, GM has released a statement moments ago reporting they have halted the production of the 3.0-liter engine.
Per GM, this stoppage is because of a supplier issue. There is no word on when this issue will be resolved but for the time being, engine production has stopped. So, for those of you out there who were interested in purchasing a Silverado, Sierra, Tahoe, Suburban, Yukon, or even an Escalade, you may be waiting a while. I’m not sure what inventory looks like but it seems like there has been a shortage with quite a few brands.
“We have currently stopped production of trucks with the 3.0-liter Duramax diesel engine due to a parts shortage,” said Megan Soule, Chevrolet Trucks, and Full-Size SUV Communications. “We will resume production of the Duramax engine as soon as possible.”
3.0-liter I6 Fun Facts
While being offered in all of GM’s full-size pickup trucks, they’re also available in the new SUVs. With a horsepower output of 277-horsepower at 3,750 rpm, that translates to 460 lb/ft of torque at 1,500 rpm. This turbocharged inline six features an aluminum head block as well as a forged connecting rods and crankshaft. Other internal reinforcements include iron cylinder liners making this engine tough as nails.
The fueling system incorporates a common rail with direct fuel injection. Induction air is chilled using a liquid-to-air intercooler. By offering loads of low-end torque, makes it a great option for towing duties. On top of the power and towing capabilities, the 3.0 offers savings on fuel costs with its impressive economy.
When equipped in the ’21 Chevrolet Suburban, the 3.0 offered 21 mpg in town and 27 on the highway. For something that can load the family up and tow a camper or a boat, that is sweet.
