The new 2027 GMC Sierra 1500 is here and it offers more power and luxury than ever before. We have all the details right here. Let’s figure out if GMC just outdid the new 2027 Chevy Silverado 1500 and all other competitors including Ford, Ram, and Toyota.
New Exterior
The new Sierra has updated styling which reminds us of the GMC Sierra EV pickup trucks. It’s not identical, but there is a lot of family resemblance. Our first impressions are very positive, the new Sierra looks fresh and premium. This is exactly what they are going for. The Sierra AT4X and Denali trucks continue to be very popular. These are expensive, capable, and luxurious trucks. GMC is looking to capitalize on these higher-end trims ever more.
The New Trims
The updated 2027 GMC Sierra 1500 lineup includes the following trims: Pro, Elevation, AT4, AT4X, Denali, and Denali Ultimate.
The Pro is the base model. It’s where it all starts. These first images show the Sierra 1500 Pro in a crew cab configuration, so it’s unclear if it will continue to be offered in shorter double-cab or regular cab configurations. Chevrolet says their 2027 Silverado 1500 work truck will be available in a regular two-door cab with 2WD.
The Sierra 1500 Elevation is the volume trim. This is the mainstream truck that is the most popular model. It goes up to the AT4 model from there literally and figuratively. The AT4 is an off-road model that has a suspension lift and 34-inch diameter all-terrain tires. This Sierra has a distinct front end with vertical red tow points inside the front bumper.
Next up is the AT4X off-road trim level returns as well. It now gets upsized 35-inch all-terrain tires. The AT4X has front and rear locking differentials, DSSV spool-valve dampers by Multimatic with additional Jounce Control Dampers. The front end features horizontal red tow points. The AT4X AEV Edition package will continue as well. This is a specialized off-road package with additional off-road armor.
The luxury truck lineup includes the Denali and the Denali Ultimate trim levels. The Denali brand is celebrating 25 years of heritage and these trim levels feature distinct front ends and new 22-inch wheels.
Powertrains & Capability
The 2027 Sierra 1500 lineup will offer a choice of four powertrains. They are an updated 2.7L TurboMax four-cylinder turbocharged engine, 3.0L Duramax I6 turbo-diesel, a new 5.7L V8, and a new 6.6L V8. All of these engines are paired to a 10-speed automatic transmission. The base 8-speed automatic is no more.
GMC did not disclose horsepower or torque numbers for any of these engines. GMC will not offer any hybrid powertrain for their new full-size trucks. If you are looking for an efficient engine option, you should look at the 3.0L Duramax turbo-diesel. This engine is ideal if you drive a lot of miles every day and drive at higher highway speeds.
If you are looking for an efficient electric powertrain, GMC still offers the Sierra EV in several trims. These EV trucks also offer a high level of export power.
New Interior
The new Sierra 1500 interior takes it up a notch once again. You will not confuse it for a Silverado interior. It stands apart with sophisticated horizontal layout. GMC says they are offering over 60 inches of total screen real estate. This includes a 16.3-inch center infotainment screen that electrically articulates up to reveal a large storage cubby. On some trims, the passenger gets a 11.5-inch screen that has its own motorized cover. The drive gets a 12 inch gauge cluster, a large heads-up display and a digital camera rear view mirror.
The new Sierra 1500 introduces a new MultiPro center console that incorporates sliding cup holders, a large storage area, and folding armrest that can open up into a flat surface.
The new 2027 Sierra 1500 truck lineup will go on sale by the end of this year (2026). GMC has not announced pricing or any other specifications at this time. We expect to see and test drive these trucks in person soon.
