General Motors’ flagship engine for its heavy-duty pickup trucks is the 6.6-liter Duramax turbodiesel V8. A new offering for 2017, it has already found a dedicated fanbase.
The Duramax provides the Chevrolet Silverado HD and GMC Sierra HD with a hefty 445 horsepower and 910 pound-feet of torque — enough to tow more than 20,000 pounds of cargo in some configurations.
To learn more about the Duramax, we tracked the engine back to its origins as a chunk of molten steel in Germany and followed its path along the assembly line to become the heart of a top-selling pickup truck. Watch the video below to see how GM breathes life into the Duramax engine.
