The 2025 Chevrolet Silverado 2500HD belongs to the fourth-generation series of this revered heavy-duty pickup that was unveiled in 2019. Buyers are offered two powertrain options: a standard 401-hp 6.6L V8 gasoline engine, or an optional 445-hp 6.6-liter turbodiesel V8. Both engines pair with a robust 6-speed or 10-speed automatic transmission, except the turbodiesel that employs a stout Allison® 10-speed automatic transmission. The Silverado 2500HD comes in five available trims: Work Truck (WT), Custom, LT, LTZ, and High Country, all having rear-wheel drive (RWD) configuration, with available option to upgrade to four-wheel drive (4WD). Key safety features include the StabiliTrak stability control system, Proactive Roll Avoidance and traction control, with optional packages offering advanced driver assistance systems. The truck gets a state-of-the-art infotainment system offering a standard 7.0-inch or optional 8.0-inch touchscreen integrated with Apple CarPlay and Android Auto. Notable changes in this model year include exterior refreshment and interior enhancements.
