DETROIT – General Motors revealed its 2027 GMC Sierra 1500 pickup truck lineup on Thursday with new V-8 engine options and redesigned interior and exterior styling.

The new GMC trucks are crucial to the automaker's sales and earnings, especially the highly profitable Denali luxury models and off-road AT4 models that represent roughly half of the vehicle's current sales, according to GM. Such models feature unique parts, accessories and amenities to boost pricing and profits for the company.

GM said Thursday it's narrowing its model lineup for the next-generation Sierra to the Pro, Elevation, AT4, AT4X, Denali and Denali Ultimate. It's removing the mid-level SLE and SLT trims, which currently start at about $51,500 and $57,900, respectively.

GM said pricing details as well as performance specifications will be released closer to when the vehicles go on sale late this year. Starting prices for the current Sierra 1500 lineup ranges from roughly $41,000 for an entry-level Pro to more than $86,000 for a Denali Ultimate.

"With the next-generation Sierra 1500, we're bringing together a new generation of Small Block V8 power, precise off-road capability, and our most immersive cabin experience to date," said Michael MacPhee, vice president of GM's GMC and Buick brands, in a release. "The next-generation Sierra is the truck all others will be measured against."

The new trucks come a week after the Detroit automaker unveiled updates to its Chevrolet Silverado 1500 pickup trucks, which are mechanical siblings to the GMC models.

Most noticeably the GMC pickups are styled far differently than their Chevy brethren, including taking styling cues from the brand's all-electric Sierra pickup truck and featuring a new interior.

The interior cabin comes with more storage, a sliding center console and a folding table or work surface — all made possible by moving the gear shifter from the center console to behind the steering wheel. It also features new technologies and more than 60 inches of available screens, including an 11.5-inch passenger-side screen that includes media and entertainment functions.

Other significant changes are found under the hood. Like the Silverado models, the GMC pickups will include a new generation of the automaker's small block V-8 gas engines, available in 5.7-liter and 6.6-liter options.

In addition to the V-8 engines, the GMC trucks will offer two six-cylinder engines, including a GM-exclusive diesel variant.

GM's U.S. sales through the first half of this year are forecast to decline by roughly 7%, according to Cox Automotive. The overall market is expected to see sales fall roughly 3%, Cox said Wednesday.

GM reported first-quarter sales were down 9.7% compared with a year earlier, with its GMC brand about level. Sales of the Sierra 1500 were down about 2% to nearly 51,900 units, while larger, heavy-duty models were off about 8% to roughly 24,500 units. Sales of the electric Sierra were up 3%, but remained under 1,300 units.
