Set to launch in GM’s 2023 Silverado 1500 and 2023 Sierra 1500, the new GM 3.0L I6 LZ0 turbo-diesel Duramax motor takes the place of the Duramax 3.0L I6 LM2, which was offered from the 2019 thru the 2022 model years in these pickups. The new diesel engine is capable of producing 305 horsepower and 495 pound-feet of torque, which represents a 10 percent increase in power and a 7.6 percent increase in torque over its predecessor. It also features upgraded steel pistons and a revised combustion bowl, along with a revamped turbocharger compressor, redesigned fuel injectors along with improved temperature control. Comparatively, the Ford 3.5L V6 PowerBoost offers 430 horsepower and 570 pound-feet of torque in the 2021, 2022 and 2023 Ford F-150.

A very direct rival from Ford to the GM’s new LZ0 Duramax engine would have been the Ford 3.0L Power Stroke diesel engine, code-named Lion. Alas, this motor was discontinued last year, so we’re going to consider the Ford 3.5L V6 PowerBoost engine – which mates Ford’s legendary 3.5L EcoBoost V6 to a hybrid system – as the closest competitor to GM’s new 3.0L baby Duramax engine. Given that the PowerBoost is more potent, both in terms of horsepower and torque, than the new Duramax, it would seem that the diesel in the F-150 was simply not all that attractive, if not unnecessary.

    I think that power and torque of the powerboost disappears once you put a load behind it and certainly the mpg does to low single digits.
    Bring back the 3.0 Powerstroke Diesel.

    The reason the 3.0L Powerstroke didn’t do well it’s because no one wanted to pay a premium for an engine that was no better than the naturally aspirated base V-6 and the costs associated with maintaining it.
