GM Teases New Duramax Diesel 8.3-Liter V-8 Engine Called ‘Mongoose’

And the automaker isn’t shying away from calling out the competition on the other side of Detroit.

The arms race between heavy-duty pickup-truck makers is alive and well, even as much of the auto industry focuses on electrifying its lineups. Still, Detroit’s Big Three continue to push the limits of combustion engines, especially with their biggest trucks, and General Motors has just upped the ante one more time.

In a new YouTube video, GM just announced a new Duramax diesel 8.3-liter V-8 engine bound for its heavy-duty pickups. Aside from the displacement, we don’t have any engine specs yet. Still, we can be sure that the Mongoose is riddled with superlatives.

Heck, GM is abundantly clear about targeting the competition. There’s the name itself: Mongoose, which is a clear shot at Ford’s “Scorpion” 6.7-liter Power Stroke diesel, which powers the brand’s heavy-duty trucks. And then there’s the video, which shows a bow-tie-eyed Mongoose attacking and killing a Scorpion that just so happened to be walking in an oval.

So while we don’t know the high end of the Mongoose’s stats, we can be sure of the low end. Considering that the Power Stroke generates 500 horsepower and 1200 pound-feet of torque, the Mongoose is sure to outdo those figures.

6-liter V-8, which churns out 470 horsepower and 975 pound-feet of torque. Those might be respectable figures, but in the world of HD trucks, no one wants to be outdone by their rivals.
