Chevrolet today announced the 2020 Silverado’s first-ever optional 3.0-liter Duramax inline-six turbo diesel offers “class-leading torque and horsepower” with an eye toward fuel economy and capability.

The Duramax is priced identically to the optional 6.2-liter V-8 as a $2,495 premium over the 5.3-liter V-8 model, or $3,890 over the 2.7-liter Turbo model.

Available on LT, RST, LTZ and High Country models, the 3.0-liter Duramax diesel rounds out the new Silverado’s range of six engine choices, each tailored to suit customers’ needs for performance, efficiency, technology, and value. It is rated at 277 horsepower and 460 lb.-ft. of torque, delivering 95 percent of peak torque at 1,250 rpm. Peak torque is sustained from 1,500 rpm through 3,000 rpm.

The Duramax is paired with General Motors Co.’s 10L80 10-speed automatic transmission, which features a centrifugal pendulum absorber torque converter that reduces vibrations to improve smoothness, reinforcing its performance, efficiency and refinement. This combination also offers exhaust braking, which uses the diesel engine’s compression to help slow the vehicle, requiring fewer brake applications by the driver when in tow-haul mode.

Among the Duramax’s features are a lightweight aluminum block, active thermal management, ceramic glow plugs, water-charge air cooler, a tuned-air induction system, noise-attenuating elements, variable-geometry turbocharging, low-pressure exhaust gas recirculation, and a variable-pressure oiling system.

Stop/start technology helps optimize efficiency in city driving. The driver-selectable system shuts off the engine at stoplights and other stop-and-go situations. The engine automatically restarts when drivers takes their foot off the brake.

“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,” says Nicola Menarini, director of diesel truck engine program execution at Chevrolet. “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.”
