Originally slated for the 2019 Chevrolet Silverado 1500, General Motors’ all-new Duramax turbo-diesel engine will be offered for that truck’s 2020 model year instead.

This engine, a 3.0-liter inline-six, is rated for 277 horsepower and 460 lb-ft of torque — more powerful than the Silverado’s top competitor, the Ford F-150. It comes paired with a 10-speed automatic transmission. According to GM, it will be available on four 2020 Silverado trims: the LT, the RST, the LTZ, and the High Country.

“From the moment the engine is started to its idle, acceleration, and highway cruising, the 3.0-liter Duramax performance will change perceptions of what a diesel engine can offer in refinement,” said Nicola Menarini, GM’s diesel truck engine director. “With advanced technologies that draw on global diesel expertise, it’s a no-compromise choice for those who want the capability and driving range of a diesel in a light-duty truck.”

The new engine is built with efficiency-boosting lightweight aluminum. The inline-six layout helps reduce friction and allows for smoother, quieter operation. Active Thermal Management technology further improves the engine’s efficiency by helping it warm up faster in cold weather. When the vehicle is in tow/haul mode, the engine and transmission work together to allow exhaust braking and reduce wear and tear on the regular brakes.

Other technologies incorporated into this engine include variable geometry turbocharging, low-pressure exhaust gas recirculation, a variable intake manifold, a variable-pressure oiling system, an electronic throttle valve, and stop/start technology.

Silverado models equipped with the 3.0-liter Duramax turbo-diesel will be priced the same as models that carry a 6.2-liter V8. That’s $2,495 more than a 5.3-liter V8 and $3,890 more than a 2.7-liter four-cylinder turbo.
