General Motors will finally fit a diesel engine to its bread-and-butter half-ton pickup truck. The automaker’s new 3.0-liter Duramax inline-six diesel engine will debut in the 2019 Chevrolet Silverado, and it’s all but certain the 2019 GMC Sierra will also feature the new powertrain.
That leads us to question the engine’s next act. Will GM fit the 3.0-liter Duramax inline-six diesel engine to its next-generation full-size SUVs? Tracing GM’s track record with diesels as of recent, we think that’s a safe bet at this point.
And the next-generation Chevrolet Tahoe, Suburban, GMC Yukon and Cadillac Escalade would benefit greatly in the fuel economy department. Plus, it would give GM bragging rights to introduce the first full-size SUV available with a diesel engine. It’s entirely possible Ford will offer the new Expedition with the F-150’s new 3.0-liter V6 Powerstroke mill.
Final specifications on the 3.0-liter Duramax diesel aren’t available yet, but GM product chief Mark Reuss noted at the 2019 Silverado’s debut that he was “really confident that we’ll have the best-performing diesel in this segment.” Ford’s half-ton diesel engine produces 250 horsepower and 440 pound-feet of torque.
GM has been on a diesel kick in recent years as it banks on oil burners to help with its average fuel economy figures. The Cruze, Colorado, Canyon, Equinox and Terrain all offer diesel engines. We think the 2019 Chevrolet Malibu could be on deck, too.
