Engines: Four Options, Every One With a 10 Speed Automatic

Every 2027 Sierra 1500 engine pairs with a 10 speed automatic. Here’s the full lineup with GM’s published output and where each engine lands in the trim walk.

The two V8s are GM’s sixth generation Small Block, with new combustion, cooling and fuel injection systems. The Duramax carries over and stays the only diesel offered in the half ton segment. GM says a diesel with the available 34 gallon tank can go more than 900 highway miles on a fill, based on GM’s own 27 mpg highway estimate for 2WD. Official EPA numbers aren’t out yet, and we’ll update this page when they are.

2027 Sierra 1500 Towing and Payload

Here’s what each engine can pull and carry, per GM’s September spec release. Max figures depend on cab, drivetrain and package, so the configuration is listed with each number.

A 5.7L Crew Cab 4WD with the Max Trailering Package is rated at 13,300 pounds, so you don’t give up much by going Crew Cab. New for 2027 is an available Trailer Brake Gain Assistant, an industry first, plus up to 19 available camera views including underbody cameras with a wash system. Max trailering ratings are for comparison only. See the trailering disclaimer at the bottom of this page.

Available welcome and farewell lighting animations, available illuminated GMC lettering, and available quad exhaust finish it off. AT4X gets its own hood and the 2 inch lift.

Should You Wait for the 2027 or Buy a 2026 Sierra 1500 Now?

The 2027 brings the new V8s, the new cabin and the new standard safety list, but the first wave is Crew Cab only, Pro is late availability, and early allocation will be tight.
