Revamped 2024 Chevrolet Silverado HD gets upgraded diesel engine, technical updates and ZR2 off-road model : News

  • Chevrolet announced the updated 2024 Silverado HD lineup on Monday.
  • This updated HD lineup adds a few new trim options (including a ZR2), powertrain upgrades, styling changes and improved technology.
  • The 2024 Chevrolet Silverado HD will make its public debut at the State Fair of Texas later this week.
  • After that, the new Silverado HD lineup will go into production at GM’s Flint plant in Michigan and the Oshawa plant in Canada in the first half of 2023.
    • It will be a staggered launch, with the ZR2 and select options from the rest of the 2024 Silverado HD lineup arriving later.

If you’ve been waiting on the edge of your seat for HD truck news, then you’ll want to stick around this week. First up, we have the 2024 Chevrolet Silverado HD, which enters the fray with a host of significant changes. While the styling changes are on par with the mid-life refreshes – and we get that right here – Chevrolet is also aiming to make its powertrains and technology more competitive with the current heavyweight pack.

2024 Chevrolet Silverado HD: Styling Changes

On the outside, Chevrolet says it has worked to give the truck a “more commanding presence” through its exterior design. What that means for you and me is a revised fascia, including an updated grille and headlight design. Depending on your reaction to the truck’s initial redesign in 2020, this could be a welcome change. Designers of the updated Silverado HD have incorporated the headlights into new C-shaped uninterrupted daytime running lights. Higher-end models get dual-projector LED lights, with an animated welcome/leave feature similar to what we let’s see with the updated Silverado 1500 line.

Other exterior updates include “CHEVROLET” script on the hood scoop, standard tow hooks (yes, Chevy was keen to mention that), and six new exterior colors. New shades include Sterling Grey, Dark Ash, Radiant Red and Auburn Metallic. Two late availability colors will be Lakeshore Blue Metallic and Meteorite Metallic. Features you’ll still get in this refreshed truck include corner and side bed steps, a six-position Multi-Flex tailgate (with a power tailgate option), and a 120-volt bed outlet.

Interior updates

Along with the exterior changes, the 2024 Chevrolet Silverado HD also gets an updated interior, at least on most trims. WT and Custom base trims will retain the old design. The LT, LTZ, ZR2 and High Country models, meanwhile, have a much fresher look. This includes a new 12.3-inch digital instrument cluster seen on the Silverado 1500 and Tahoe/Suburban SUVs. Complementing this is a 13.4-inch infotainment screen angled towards the driver.

Chevrolet incorporated quite a few changes from the half-ton Silverado, including most of the switch layout, keeping most of the popular controls as physical knobs and buttons. Unlike the smaller truck, however, you still get a column shifter across the range. Other notable updates include many leather-wrapped items and wood trim on select models like the High Country. There’s a new center console with wireless charging available on LT models and up, and second-row passengers also get their own climate vents and controls.

Enter Powertrain Changes

While some people may worry about looks, the capability of the 2024 Chevrolet Silverado HD is what really will make or break the deal. There’s (mostly) good news on that front, as we’re getting more power from the 6.6-liter Duramax turbodiesel. Not only that, but the 6.6-liter gasoline V8 also gets the Allison-branded 10-speed transmission, so pour one in for the old 6-speed. In fact, I doubt many people will actually miss it and appreciate the wider gear ratio spread to get the most out of this gasser’s available power.

Sticking with diesel first, though, here are the headline numbers: 470 horsepower and 975 lb-ft of torque. That’s a substantial increase over the 445 horsepower and 910 lb-ft figures of the old trucks, but it’s still not a “top notch” output. Torque, published to SAE J1349, is lower than both Ford (1,050 lb-ft) and Ram (1,075 lb-ft), in their highest horsepower configurations. Power-wise, it comes remarkably close to the 6.7L Power Stroke’s 475hp number; and it exceeds the 420 hp of the 6.7L Cummins.

As for how it hit those numbers, Chevrolet cited upgrades aimed at improving combustion efficiency. Engineers also improved the Duramax’s low-end torque performance, to make it more suitable for low-speed cruising or towing on steep grades. Of course, we’ll have to test this truck on the Ike Gauntlet to see how it performs compared to the previous truck to validate the automaker’s claims.

What about the gasoline engine: does it get more power?

The 6.6-liter gasoline engine, meanwhile, still develops 401 horsepower and 464 lb-ft of torque. However, using four additional gears means smaller “steps” between gears. That should at least make the engine a little smoother, especially when towing, compared to the old transmission’s six-speed. As a result, Chevrolet says the 2024 Silverado HD’s GCWR with the 6.6-liter gas engine increases to 26,000 pounds, up from the previous model’s 24,000 pounds.

With changes to packaging and content, the 2024 Chevrolet Silverado HD lose some payload capacity in some configurations compared to the old truck. Towing capacities are also changing, and we’ll have a more detailed “by the numbers” look at soon.. (Update: Check out a full comparison here.)

More technical updates: Adaptive cruise control now available

Coming back to the technological changes, the 2024 Chevrolet Silverado HD does not stop at the digital cluster and the infotainment update. It also receives a slew of driver assistance updates, particularly in towing.

Adaptive cruise control while towing is the headline feature, allowing revamped models to account for increased trailer drag and braking distances when towing. The “Enhanced Clear Trailer” expands the current truck capability to include fifth wheel and gooseneck trailers. Trailer Side Blind Zone Alert extends the blind zone beyond the truck itself – a feature increasingly available in the truck market. The GCW alert is also built-in, notifying the driver if the vehicle and trailer exceed the GM-recommended GCWR figure (again, more on the numbers to come shortly). (Update: Here it is for your reference!)

The 2024 Chevrolet Silverado HD lineup retains its battery of cameras for its Bed View and HD Surround Vision systems. You still get up to 14 available camera views, plus Chevy’s in-car towing app. Built-in Google compatibility gives drivers access to texting, playing music, using maps, adjusting vehicle settings or controlling home devices via the Google Assistant.

On the safety equipment side, adaptive cruise control is new for the 2024 Chevrolet Silverado HD lineup. This complements the existing assist technology, including forward collision warning. Other safety features include front pedestrian braking, lane departure warning, a following distance indicator and automatic emergency braking.

New trim options including ZR2

While Chevrolet has gone to great lengths to talk styling changes and powertrain updates, that’s not all the 2024 Silverado HD has in store. In fact, it gets an off-road-focused ZR2 trim. Now this model will not be available until later in the year, after the initial launch of the revamped trucks in the first half of 2023. Then we’ll have more concrete information on what the ZR2 brings to the table.

The automaker also didn’t specifically mention a midrange “Trail Boss” trim. So it looks like we’ll get a Z71 package (the Z71 Sport Edition and Chrome Sport Edition stick around) and then the top-spec ZR2. To that end, we’ll have an option that, at least on paper, takes on the Ram Power Wagon and the Ford Super Duty Tremor.

On top of that, the 2024 Chevrolet Silverado also gets a blacked-out Midnight Edition. Available exclusively with the High Country trim, you’ll get dark chrome accents in the grille, along with black badging. Gloss black painted 20-inch wheels are standard, while you can get larger 22-inch wheels if you want.

More to come soon from the State Fair of Texas

Interestingly, the 2024 Chevrolet Silverado HD has made its online debut just before the updated Ford Super Duty. Of course, it doesn’t take a marketing degree to figure out why on that one.

We’ll have more information about Ford’s heavy-duty offering soon, but there will be even more this week. We’ll have more in-person coverage of this updated Silverado Heavy Duty at the State Fair of Texas, where it’s expected to make its public debut in the coming days.

Pricing information won’t be available for some time, but we’ll analyze other truck numbers in the meantime and provide those updates when we can. In the meantime, watch our news video below:
