The 4.5-liter LMK Duramax V8 engine was so close, yet so far, from being a reality. As the housing bubble burst, and the economy took a hard nosedive in 2009, General Motors was putting the finishing touches to the “baby Duramax.”
Unfortunately, in 2009, GM released an official statement scrapping the project entirely as it filed for Chapter 11 bankruptcy and consolidated brands and closed dealerships. Now, seven years later, Truck Trend has brought the zombie Duramax back as a talking point. Is there any chance it could return?
The 4.5-liter Duramax V8 was to serve as an additional engine option in the Chevrolet Silverado and GMC Sierra 1500, producing 310 hp and 520 lb-ft of torque. Those are healthy numbers for a half-ton pickup truck, and it sounds lovely. However, it’s unlikely we’ll see this engine ever surface from the graveyard.
Even with GM gracing the U.S. market with the 2.8-liter four-cylinder turbo diesel, diesels aren’t a hot commodity, especially following Volkswagen’s doing, making diesel a dirty word. There likely isn’t much of a market for the engine in a half-ton pickup.
Unless, maybe there is. Talk to us down below. Would you consider a baby Duramax diesel over a regular gasoline V8?
