The 2025 GMC Sierra HD brings exciting improvements across trims and technology. The AT4 and Denali now include adaptive cruise control with trailering assist for easier, safer highway towing. A trailer-brake controller is now standard across all models (previously optional), and the Pro and SLE trims gain front and rear parking sensors for added convenience.

Design-wise, you'll notice updated LED headlights, a refreshed front fascia, and sleek styling. Inside, features like the available 13.4-inch touchscreen with Google Built-in services, wireless Apple CarPlay and Android Auto, and up to 15 camera views keep you connected and confident.
