Sierra, Silverado 3.0L Diesel Postponed: Report

The inline six-cylinder diesel that’s set to appear in the Chevrolet Silverado and GMC Sierra 1500s is getting a model year’s delay, according to a new report.

The new 3.0L Duramax diesel is set to compete with the light-duty diesel options from Ford and Ram. It was expected to arrive for the 2019 model year, showing up earlier this year. Now, GM says that it will be pushed back to model year 2020, according to Automotive News.

That report suggests a delay in the EPA emissions certification is the reason, per a memo sent to GM dealers earlier this week. The General said that production of the 2020 trucks will start soon, but since it’s been pushed back a model year, even if it’s only a few months of actual time, then orders for 2019 trucks will need to be canceled and resubmitted. Timing for the new orders will come later.

EPA Diesel emissions certification has gotten tougher since the VW emissions scandal in 2015. Which has led to other automakers, including FCA and BMW, experiencing launch delays while waiting for certification to be completed.

GM has already announced specs for the engine, the first diesel in a half-ton GM pickup since 1997. Paired with a 10-speed automatic it will produce 277 hp and 460 lb-ft of torque. Towing and fuel economy figures are yet to be released.
