Big trucks and SUVs continue to be the backbone of GMC’s business, and American buyers show no signs of losing interest. The Sierra full-size pickup and Yukon full-size SUV remain the brand’s heavy-hitters, and while they’ve been strong performers, GMC isn’t sitting still. Designers and engineers are already deep into developing the next versions of their most in-demand models.

GMC, much like sibling brand Chevrolet, isn’t stepping away from internal combustion engines just yet. That’s proving to be a practical move as EV demand has cooled, in part due to the rollback of federal incentives under the Trump administration. But electrification at GMC doesn’t start and end with battery-electric vehicles. Plug-in hybrids are now part of the plan.

Plug-In Powertrains and Production Plans

GM CEO Mary Barra has confirmed that plug-in hybrid models will join the lineup in 2027. That same year, GM plans to ramp up production of the Sierra at its Orion Township facility in Michigan. According to Automotive News, this timing may align with a mid-cycle refresh for the Sierra, followed by updates to the heavy-duty version in 2028.

These refreshed models are expected to feature electrified powertrains as their main upgrade, alongside tweaks to styling and onboard tech. The all-electric Sierra EV could also see its own redesign in 2028, potentially bringing it more in line with its combustion-powered counterpart. As for the related Yukon and Yukon XL SUVs, a redesign is reportedly planned for 2029, and they too are expected to adopt plug-in hybrid options.

Future Updates Across the Lineup

The rest of GMC’s portfolio is also set for change. Autonews reports that the fully electric Hummer, which began production in late 2021, will likely undergo a mid-cycle refresh around 2028 for both pickup and SUV variants. The current-generation Arcadia, launched in late 2023, could be due for an update by 2027 or 2028. Meanwhile, the Canyon midsize pickup is expected to get a refresh in 2029, six years after its debut. The GMC Terrain is also quite fresh, so don’t expect a facelift before 2028 or 2029.

The aging GMC Savana van is expected to stick around at least through 2026, with some reports suggesting a potential production expansion. First introduced in 1996 and largely unchanged since then, the Savana continues on alongside its Chevrolet Express twin.

Growing Sales Driven By the Full-Size Segment

Sam Fiorani, Vice President of Global Vehicle Forecasting at AutoForecast Solutions, pointed to the strong position GMC holds in the full-size market: “Trucks are such an important part of the U.S. market, and GMC has cornered the segments that are a bit more upscale than Ford or Chevrolet.”

That strategy appears to be paying off. GMC posted its best-ever first-half sales in 2025, reaching 315,906 units, an 11 percent increase over last year. The Sierra alone accounted for 166,409 of those sales, up 12 percent. The Yukon followed with 48,190 units sold, a 22 percent increase.

The only drop came from the Terrain compact SUV, down 34 percent with 32,361 units sold. On the other end, the Hummer EV saw the largest percentage gain in the first half of 2025, climbing 74 percent to 7,987 units. Still, it remains GMC’s second slowest-selling model, just ahead of the newly introduced Sierra EV, which logged 2,774 units in the same period.

General Motors has finally acknowledged the obvious: no one is buying the Chevrolet Silverado EV and GMC Sierra EV. As we recently noted, the company only sold 2,383 Silverado EVs and 1,249 Sierra EVs in the first quarter.

Those are dreadful numbers, and they appear to have been the final nail in the coffin for plans to turn Orion Assembly into an EV plant. The facility was originally slated to build electric trucks in 2024, but that date was eventually pushed back to late 2025 to “better manage capital investment, while aligning with evolving EV demand.”

Fast forward to today, and GM has thrown in the towel on its electric truck plans. Instead, Orion Assembly will now build gas-powered full-size SUVs and trucks starting in early 2027. The move means the plant will likely produce the redesigned Chevrolet Silverado, Tahoe, and Suburban as well as the GMC Sierra, Yukon, and Yukon XL.

As for the Silverado EV and Sierra EV, they’ll continue to be built at the nearby Factory Zero in Hamtramck. That facility also builds the GMC Hummer EVs as well as the Cadillac Escalade IQ.

The Gas-Powered Chevrolet Blazer Lives

The aging Chevrolet Blazer was expected to be discontinued, but it’s getting a reprieve as production will begin at Spring Hill Manufacturing in 2027. That facility is best known for making the electric Cadillac Lyriq and Vistiq, but it also builds the dated XT5 and XT6.

Speaking of EV plants doing double duty, Fairfax Assembly is slated to begin building the 2027 Chevrolet Bolt EV by the end of this year. However, it’s getting some company in the form of the gas-powered Chevrolet Equinox, which will be built at the plant in mid-2027.

GM said the move will help support sales of the popular crossover, which was “up more than 30% year-over-year in the first quarter.” However, it’s important to note the model is currently built in Mexico, and this could have played a role in shifting some production stateside.

Unsurprisingly, GM didn’t mention tariffs or slower-than-expected electric vehicle adoption in today’s announcement. Instead, they packaged it in Trump-friendly form as CEO Mary Barra said, “Today’s announcement demonstrates our ongoing commitment to build vehicles in the US and to support American jobs.”

She added, “We’re focused on giving customers choice and offering a broad range of vehicles they love.” That’s a not so subtle hint that gas-powered vehicles aren’t going away anytime soon.

GM said the investments total around $4 billion, which is roughly the same amount of money they were investing in transforming Orion Assembly into an EV truck hub. This begs the question of how much money was squandered on the bad EV bet.
