What changed on the 2027 GMC Sierra 1500?

For 2027, GMC lists a TurboMax engine with a 10-speed automatic as standard on the Pro and Elevation, a 5.7L V8 on the AT4 and Denali, the 3.0L Duramax Turbo-Diesel on the AT4X and a 6.6L V8 on the Denali Ultimate, each with a 10-speed automatic. For 2026, the V8s were a 5.3L and a 6.2L, and the 2.7L TurboMax used an 8-speed automatic.

The 2027 Pro starts at $39,300, the Elevation at $50,200, the AT4 at $70,700, the Denali at $70,900, the AT4X at $82,700 and the Denali Ultimate at $85,100, against $38,300, $50,500, $67,000, $66,100, $79,600 and $84,400 for the same trims in 2026.

The EPA rates the 2027 5.7L V8 with two-wheel drive at 15 city, 19 highway and 17 combined, and the 3.0L Duramax with two-wheel drive at 22, 27 and 24.

What does a 2027 GMC Sierra 1500 cost in Houston with Texas tax?

Texas charges 6.25% sales tax on a new truck, calculated on the sales price minus your trade-in allowance (Texas Comptroller of Public Accounts, 2026). The state registration fee is $51.75 for a truck of 6,000 pounds or less, which is $50.75 plus $1 for TexasSure, and a $4.75 processing and handling fee applies on top (Texas Department of Motor Vehicles, 2026).

On a 2027 Elevation at its $50,200 starting MSRP with no trade-in, tax at 6.25% comes to $3,137.50. Registration adds $56.50, and the title fee for a buyer living in Harris County adds $33 (Texas Department of Motor Vehicles, Motor Vehicle Title Manual, 2026). That makes $3,227.00 in tax and fees before any county fee.

County fees are set by each county and range from $0 to $31.50 (Texas Department of Motor Vehicles, 2026). Bring the trim and price you are considering, and add these figures to it.

What warranty comes with the 2027 GMC Sierra 1500?

GMC’s published wording reads: “Covers the entire vehicle for repairs, including parts and labor, to correct any defect in materials or workmanship for 3 years or 36,000 miles, whichever comes first.” (GMC, Vehicle Warranty and Protection Plans).

Powertrain coverage typically lasts 5 years or 60,000 miles, whichever comes first (GMC, Vehicle Warranty and Protection Plans).

Say, hypothetically, you drive 20,000 miles a year. At that pace, you reach 36,000 miles in 1.8 years and 60,000 miles in 3 years. Mileage, not the calendar, sets the end of both coverage periods.
