Silverado Diesel Half-Ton Promises More Power Than Ever

It has been a most unusual year for the diesel pickup market. Demand for diesel powered trucks remains high, but chip shortages have produced hiccups in fulfilling demand. This was followed by other shortages and news of a halt on production for Duramax-powered GM trucks.

Nevertheless, despite these temporary distractions, there's light at the end of the tunnel and plenty of buzz-producing stories circulating right now. Just yesterday Motor1 published this story titled "2023 Chevrolet Silverado HD Could Get Diesel With Over 500 HP: Report."

As is well-known, Ford F-Series trucks have been the top selling pickup for years. Ram Trucks have had a fairly secure hold on second place based on both reputation and performance. Chevy, however, has not been sitting idle and with the "reveal" of their 2022 Silverado last week showed that they are making an intentional move to displace the Ram to move up the ladder in the half-ton truck hierarchy.

Last week Chevy unveiled its 2022 Silverado, and this week has revealed its plans for the 2023 season. That's what yesterday's report at Motor1 was about.

The article begins by Chris Bruce begins by noting that the largest pickups in the family are still under wraps. GM's spotlight is on the half-ton, calling the Silverado ZR2 "the new flagship off-roader in this model's lineup." The focus is not on styling here. Leadership in the realm of horsepower and torque is the target for Silverados of the future.

Bruce begins with details about how comfortable the truck is before giving us a look under the hood. Here you will find a naturally aspirated 6.2-liter V8 engine that has a lot of gumption, producing 420 hp and 460 lb-feet of torque. This is hooked up to a 10-speed automatic transmission with extra features to assist in maximizing traction. It also has a "Terrain" driving mode for crawling.

The writer details aspects of the "new look" on this machine as well as tech upgrades and interior improvements, including a fully customizable instrument display. There are gizmos galore. The Safety Assist Suite has collision alerts, lane keeping assistance, automatic emergency braking, and other technically advanced safety features. We've come a long ways since Ralph Nader's Unsafe at Any Speed over 55 years ago.

It's the powertrain upgrades that most interest us here. There are actually four engines available for the 2022 Silverado. They are the turbocharged 2.7-liter four-cylinder, 5.3-liter V8, 6.2-liter V8, and 3.0-liter inline six-cylinder diesel. Describing their capabilities, Bruce writes, "The turbocharged 2.7-liter four-cylinder now makes 310 hp (231 kW) and 420 lb-ft (569 Nm), rather than 310 hp and 348 lb-ft (472 Nm) for the current version. This lets rear-drive versions of the truck now tow up to 9,600 pounds."

And then there is this surprise: a Silverado with a rear-drive 3.0-liter inline-six turbodiesel that can purportedly tow as much as 13,300 pounds. Over six-and-a-half tons. That's a 28 percent increase in towing capacity, achieved in part by a strengthened chassis, improved cooling and 3.73 drive ratio (as opposed to the standard 3.23 ratio.)

The article goes into greater detail than we're providing here, and there are plenty of photos to whet your appetite for more.
