A styling refresh and some interior improvements give the 2025 Suburban a fresh look. Chevy's biggest SUV gets a new 17.7-inch infotainment system standard, a new 11.0-inch digital gauge display, new towing-assist features, wider availability of GM's Super Cruise hands-free driving system, new wheel designs (including some huge 24-inch rollers), and chassis improvements to improve ride comfort and handling. The optional diesel inline-six gets more power and now makes 305 horsepower and 495 pound-feet of torque, but the Suburban's V-8 gasoline engines carry over unchanged.
