2026 Chevy Silverado 2500HD Specs, Interior, Specs – There’s no denying that the Chevy Silverado 2500HD – as well as the mechanically identical GMC Sierra – has fallen behind its rivals in recent years. Well, everywhere except in the sales charts, that is, with this half-ton still selling in huge numbers despite being decidedly dated compared to the Ford F-150 and Ram 1500. Where its rivals took massive leaps forward a few years ago to integrate modern technology and attractive materials, the Silverado felt a generation or two old and stayed that way – until now, that is. 2026 Chevy Silverado 2500HD Specs
While stopping short of new-generation status, the 2026 Chevy Silverado 2500HD has been significantly updated in all the ways that matter. The mechanicals weren’t the problem before, so they remain mostly unchanged, with the brand instead bestowing upon this truck the style and substance it needs to feel sufficiently up-to-snuff in the segment.

2026 Chevy Silverado 2500 HD Redesign and Update Plan
Exterior and Interior
From its most basic form as a construction truck to its most elaborate crew cab, the heavy-duty Silverado offers it all. A towering dashboard brimming with user-friendly controls is standard on all of them. Improved passenger room, longer wheelbase, and new climate vents and controls for the back seat are all features of the Chevy’s crew-cab, short-box design. 2026 Chevy Silverado 2500HD Specs
The Silverado’s cabin and features surpass ordinary truck pleasures, even though even the most extravagant variants can’t compete with the Ram HD’s material quality and complexity. Front and back heated seats with ventilation, a heated steering wheel, heated seats, a head-up display, and other features are quite desirable. The Chevy boasts an enormous center console bin and an abundance of internal cubby storage. In addition, there are models that come with storage bins integrated into the backs of the rear-seat cushions and a compartment under the back seat.

While the exterior has been updated at least a little, it’s the cabin that deserves all the praise for its enhanced aesthetics and features. While the base trim is stuck in the past, both literally and figuratively, the rest of the lineup gets a much-needed new look and feel. Materials and controls have been swapped out for stuff that’s a little more refined, while a 13.4-inch touchscreen acts as a centrepiece of form and function.
According to the automaker, Canadian software teams were behind much of the development of the Silverado’s new infotainment interface, which was good before but inches closer to outstanding status. While wireless Apple CarPlay and Android Auto connections are included, as they were before, a new built-in Google assistant can be used to control various functions including climate, phone, or audio, plus Google Maps takes the place of a traditional onboard navigation system.
Working in conjunction with the infotainment system is a 12.3-inch digital instrument cluster that’s crisp and configurable, while a whole host of new controls are a massive step forward in both form and function. Where the switchgear of old was cheap and chunky, this stuff is nicer to look at while remaining simple to use and understand. There’s no more tune knob on the centre stack, which is a shame, but there’s a button, toggle, or dial for just about every other function in the truck. 2026 Chevy Silverado 2500HD Specs
Engine and Performance
The bad news first: there’s no hybrid or electric powertrain to pick from here, with a pair of V8s on offer, as well as a turbocharged four-cylinder gas engine and an inline six-cylinder diesel. (An all-electric truck bearing the Silverado name is expected to arrive sometime next year.) The 2.7L turbo has been tweaked slightly as part of the Silverado’s updates, with a helpful torque boost to 420 lb-ft. For a bit of context, that’s quite a bit more than this truck’s 5.3L V8 generates.
Despite not sounding all that impressive, a brief test of a four-cylinder Silverado proved perfectly pleasant, with acceleration that’s competent and competitive with rivals that use larger engines to get the job done. Of course, those looking to access a more traditional truck experience through the pedal on the right will find it in the 6.2L V8 that’s standard in the all-new Silverado ZR2 and is available elsewhere in the lineup, including the luxury-leaning High Country trim.
With 420 hp and 460 lb-ft of torque, this naturally aspirated unit is paired with a 10-speed automatic transmission instead of the 2.7L’s eight-speed, and there’s an entire theatrical performance that accompanies prods of the accelerator. The exhaust note isn’t quite as invigorating as the Ram 1500 GT’s sublime sound but it adds to the sensation of forcefulness the 6.2L provides.
2026 Chevy Silverado 2500 HD Fuel Economy
The Silverado 2500HD is offered with a gasoline or turbodiesel V-8 engine, both displacing 6.6 liters and connected to an Allison 10-speed automatic transmission. Base trucks are RWD as standard, while 4WD is offered or included depending on trim. The gasoline engine makes 401 hp and 464 lb-ft of torque. Expect a 0-60-mph acceleration time of approximately 7.0 seconds. Given the truck’s heavy-duty classification, it’s not required to be tested for fuel economy—don’t count on it to be good. 2026 Chevy Silverado 2500HD Specs
We much prefer the available Duramax turbodiesel V-8, which churns out 470 hp and 975 hp. With this engine, the 2500HD hustles to 60 mph in just 6.6 seconds. Fuel economy may be better than with the gas V-8, but still doesn’t excel, coming in at about 16 mpg in mixed driving during our assessments.
2026 Chevy Silverado 2500 HD Safety Features
All versions of the 2025 Silverado 2500HD have forward collision warning, front automatic emergency braking, a following distance indicator, and lane departure warning. Optional or included depending on trim are driver assist features such as blind-spot monitoring (with trailer blind-spot functionality), rear cross-traffic alert, and adaptive cruise control. Lane keep assist is sorely missing from these assist systems. 2026 Chevy Silverado 2500HD Specs
2026 Chevy Silverado 2500 HD Price and Release Date
It’s probably fair to describe the Silverado High Country as a short step behind similar Ram 1500 and Ford F-150 models as far as luxury goes (there are still no massaging seats available, for instance), the availability of the brand’s Super Cruise driver-assist system nearly makes up for it. Part of a pricey $9,000 package that also adds a power sunroof and retractable side steps, the system functions on vetted stretches of divided highways for completely hands-free driving. 2026 Chevy Silverado 2500HD Specs
It’s also been updated to include lane-change capabilities, with both automated and on-demand options. The former responds by automatically changing lanes to get around slower moving traffic ahead, while the latter does so when prompted by the driver via the signal stalk. It all worked seamlessly over the course of about 32 km of testing in California, responding well to the truck’s surroundings and keeping up with the flow of traffic just fine.
