Overview
- General Motors revealed the redesigned 2027 GMC Sierra 1500 on June 25, 2026, showing new exterior styling, a reworked interior layout, and a trimmed model slate.
- The powertrain lineup adds two new small‑block V‑8s (5.7L and 6.6L) alongside updated V‑6 options and a GM‑exclusive diesel, but GM has not published official horsepower or torque figures.
- GMC narrowed the trim choices to Pro, Elevation, AT4, AT4X, Denali and Denali Ultimate as it shifts away from midlevel SLE and SLT versions to focus on higher‑margin Denali and off‑road AT4 sales.
- The interior emphasizes screens and flexible storage with more than 60 inches of display area on some trims, an articulating 16.3‑inch center screen, an available 11.5‑inch passenger display, a column shifter that frees up a MultiPro center console, and available headrest speakers.
- AT4 and AT4X get concrete off‑road hardware upgrades such as larger 34‑ and 35‑inch tires and Multimatic Jounce Control dampers paired with DSSV units, and GM says pricing and final performance specs will be released before the late‑year on‑sale launch.
