Delays in certification have prompted General Motors Co. to delay the U.S. debut of a new 3.0-liter inline-six diesel engine until the 2020 model year.

The engine (pictured) was to be offered as an option in 2019 model Chevrolet Silverado 1500 and GMC Sierra 1500 fullsize pickup trucks. Automotive News says the powerplant originally was expected to become available early this year.
Now dealers must cancel all orders for the engine and submit new orders for 2020 versions of the trucks, according to AN. GM hasn’t revealed how many orders are being canceled or exactly when the engine will become available.
The newspaper, citing a memo from GM to dealers, says the carmaker will offer affected customers a 2020 model truck as a replacement for the 2019 model they ordered.
The new Duramax engine is GM’s first turbodiesel for large pickups since 1997. The powerplant, to be mated with a 10-speed automatic transmission, is rated at 277 hp and 460 lb-ft of torque.
