Buyers waiting patiently for the first light-duty diesel pickup from General Motors in decades will need to wait longer. The 3.0-liter Duramax inline-six turbodiesel engine’s launch has been postponed to the 2020 model year.
Originally, GM planned for the 3.0-liter Duramax turbodiesel as a late 2019 model year option for both the Chevrolet Silverado and GMC Sierra, but the engine’s certification process has led to a delay. GM specifically called it a “slight delay” in a memo sent to dealers across the U.S.
For customers and dealers, it means all orders for pickups with the diesel engine must be canceled and resubmitted for the 2020 model year. Order books for the diesel-powered pickups are not open yet, however. It’s unclear how many orders Chevy and GMC received for the Silverado and Sierra with the new Duramax engine.
However, each customer will be offered a replacement 2020 pickup.
We still don’t know how thrifty the engine will be with regards to fuel economy, or how the oil burner will affect towing and payload ratings, but it will be a costly option. Buyers looking to add the 3.0-liter Duramax inline-six will pay $2,495 over a 5.3-liter V8 pickup. For buyers who select a trim with the 2.7-liter turbocharged four-cylinder, it will cost $3,890 more for the diesel engine.
The 3.0-liter Duramax will be paired with a 10-speed automatic transmission and make 277 horsepower and 460 pound-feet of torque. Those figures are best-in-class, topping even Ford’s light-duty diesel V6 engine.
