The refreshed half-ton 2022 Chevrolet Silverado pickup truck is still fresh in our minds, just making its debut on September 9. The bigger, heavy-duty trucks are still under wraps and will likely debut in 2022 for the 2023 model year. If the new horsepower rumors are true, the updated styling won’t be the big news for the Silverado HD. Top-class horsepower and torque will be the talk of the town.
The rumor comes from TFLtruck, which claims an insider spilled the beans on the 2023 Silverado HD release with Duramax diesel. The V8 would produce 505 horsepower (377 kilowatts) for 1,085 pound-feet (1,471 Newton-meters), which would put the Silverado HD (and its stable mate GMC Sierra HD) ahead of the pack in terms of overall horsepower. Likewise, it would also be the first full-size diesel pickup to surpass the 500 horsepower mark.

By comparison, the current Ford Super Duty is the power champ with 475 hp (354 kW) from its 6.7-liter Power Stroke V8. As for torque, that title goes to crosstown rival Ram and its 6.7-liter Cummins I6 producing 1,457 Nm (1,457 Nm) of twist. If the report turns out to be correct, GM would claim the Global Crown as the most powerful full-size pickup on the market. And when it comes to trucks, we all know how many automakers love boast of power.
At this point, it’s just an unfounded rumor and GM isn’t talking about it. That said, it’s certainly a plausible rumor given how the Detroit automakers like to steal best-in-class titles from their rivals. Considering that those stats have GM eclipsing Ford by just 30 horsepower and Ram by just 10 lb-ft, frankly, that sounds like something an automaker would do – crank things up just enough to claim the top spot.
Now that the updated half-ton Silverado is revealed, HD models are expected to follow suit for the 2023 model year. It remains to be seen if it gets a 505bhp diesel option, but with GM currently in the pipeline. lagging behind its diesel-powered competition in terms of overall horsepower, some sort of increase under the hood is pretty much guaranteed.
