Chevrolet Unveils Details and Specs for 2020 Silverado 1500 Duramax

Chevrolet has revealed details on the all-new 3.0L Duramax inline-six turbo-diesel engine which is slated to be offered on the 2020 Silverado 1500 and is the first-ever inline-six turbo-diesel offered in Chevrolet’s light-duty trucks. The new Duramax will be offered on the Silverado’s LT, RST, LTZ and High Country models and is now one of six engine choices offered for the truck and is rated at 277 horsepower and 460 lb-ft of torque, which was best-in-class until the even more recent announcement of the 3rd generation EcoDiesel engine from Ram. Ninety-five percent of peak torque is found at 1,250 rpm and full peak torque is sustained from 1,500 to 3,000 rpm which provides an incredibly smooth ride. It is built with a lightweight aluminum block and cylinder head to reduce overall mass and features Active Thermal Management which enhances efficiency for cold-weather warm-up. This plus ceramic glow plugs allow owners of the half-ton Duramax Silverado to not need a block heater until -30 degrees Celcius. For performance and efficiency, Chevrolet went with a variable geometry turbocharger, which helps provide a greater balance of both, as well as an electronically variable intake manifold to further optimize performance across the RPM band. Finally, the new engine option is paired to GM’s 10L80 10-speed automatic transmission which features a centrifugal pendulum absorber torque converter that reduces vibrations to improve its smoothness and reinforces performance and efficiency.  Pricing is not yet known but more information will become available closer to the on-sale date of the 2020 model year trucks later this year.
