The AT4 is engineered for adventure with a 3.0L Duramax Turbo-Diesel engine and 10-speed automatic, delivering impressive torque and efficiency. Aggressive 18" Goodyear Wrangler Territory mud-terrain tires and off-road-tuned suspension prepare you for rough terrain, while an integrated trailer brake controller and Tailgate with EZ Lift assist add utility. Inside, luxury meets ruggedness: Bose Premium Sound System, heated rear outboard seats, available Head-Up Display, and Rainsense automatic wipers. It's the perfect blend of refined comfort and genuine off-road capability for those who tackle both the highway and the backcountry. Ready to explore the AT4?
