The new Chevy Silverado 1500 features an optional 3.0L inline 6-cylinder diesel engine that has people talking. This Chevrolet engine is a smooth performer at all speeds, delivers impressive torque at low rpm, and brings relief at the pumps relative to gas-guzzling V8s. Here’s what it offers in a nutshell:
- 277 horsepower
- 460 lb-ft of torque
- 23 MPG city/ 31 Highway
- 13,300 lbs. max towing capacity
- Automatic Start/Stop Technologies
Chevrolet offers this DOHC inline 6-cylinder Duramax turbo-diesel engine in Silverado High Country, LT, LTZ, and RST models. It leads its competition as a light-duty pick-up truck SAE-certified Chevrolet engine in terms of towing capability, fuel efficiency, horsepower, and torque.

Powerful, Smooth, Sustainable Torque
The 2022 inline 6-cylinder diesel Silverado engine can twist out 460 ft-lb of torque, delivering 95% of that at just 1250 rpm. Near-peak torque is readily maintained between 1500 – 3000 rpm, providing a strong, fluent, and enjoyable driving experience.
This innovative Chevy engine is joined with a General Motors 10L80 10-speed automatic gearbox, equipped with a centrifugal pendulum absorber torque converter. Hypereutectic aluminum pistons also add to its low-vibration operational smoothness.
Groundbreaking Engine Technologies
The I6 3.0L turbo-diesel Silverado engine features smart technologies that enhance efficiency and optimize the driver’s experience. Lightweight aluminum cylinder heads and engine blocks reduce overall mass, while Active Thermal Management technology expedites warm-ups in cold weather.
Ceramic glow plugs accommodate shorter heat-up times, allowing quicker starts in cold temperatures. The engine’s block heater is not needed unless the temperature drops below -22 F.
A low-pressure EGR works with a water-charged air cooler to reduce torque times, and a variable geometry turbocharger improves the balance between fuel efficiency and performance. Further, an electronic variable intake manifold accentuates engine performance across the rpm range.
DOHC Rear Cam Drive & Cylinder Head
The new inline 6-cylinder Chevy engine for the Silverado features dual overhead camshafts to enhance operational efficiency. Each aluminum cylinder has four valves, each activated by no-maintenance followers with hydraulic lash adjusters to improve inward and outward airflow.
The lightweight camshafts feature 28.35 mm diameter intake valves and 24.55 mm diameter exhaust valves. The camshafts’ drivetrain is located at the rear of the flywheel side of this rather long inline 6-cylinder diesel Chevrolet engine. A chain driven by the crankshaft drives a direct-injection, high-pressure fuel pump, and a smaller chain drives the variable flow oil pump.
Variable Geometry Turbocharger
A variable geometry turbocharging system empowers the Duramax I6 Silverado engine to pump out class-leading horsepower without detracting from overall efficiency. Intricate electronic controls and closed loop-controlled vane positioning automatically increase pressure to achieve optimal power.
The water-to-air cooled turbocharger on this 6-cylinder diesel Chevy engine is equipped with a low-friction ball bearing shaft that’s positioned near the engine’s exhaust outlet, allowing a faster turbine spool-up and exhaust catalyst light-up. Maximum boost pressure = 300 Kpa absolute.
Impressive Travel Range
The 2022 Chevrolet 1500 Silverado 2WD offers a maximum highway travel range of 682 miles when equipped with the optional Duramax turbo-diesel I6 engine. This in-demand Chevy engine is a smooth operator in a class of clunky, thirsty engines. It’s efficient, powerful, capable, and priced to sell at $30,400.
