2025 GMC Sierra HD
2025 GMC Sierra HD Features & Specs
Serious power and serious trailering come standard on every 2025 GMC Sierra HD pickup. Sierra Heavy Duty's offer an available Duramax 6.6L Turbo-Diesel V8 engine that features an efficient turbocharger and Allison 10-speed automatic transmission. These innovative trucks also offer an impressive collection of trailering-assistance technologies, allowing you to trailer with more confidence than ever before. And because more views help to provide a more confident trailering experience, features such as Sierra HD's transparent trailer view, which is compatible with most traditional, gooseneck and fifth-wheel trailers, offer a more detailed look into exactly what's going on around your truck. When it comes to full-size pickup capability, it's hard for any other truck to match up with your 2025 GMC Sierra HD.
