This AT4 delivers genuine off-road engineering paired with premium amenities designed for daily driving. The 3.0L I6 engine paired with the 10-speed automatic transmission offers balanced performance, achieving 21 MPG city and 24 MPG highway. Four-wheel drive with an off-road-tuned suspension and high-clearance steps ensures you're equipped for challenging terrain, while electronic controls like hill descent manage any situation.

Inside, the cabin reflects the AT4's dual nature. Perforated leather front seats offer heating and ventilation for all-day comfort. The premium Bose audio system transforms your drive with clarity and depth. Navigation, a 15-inch head-up display, and wireless smartphone integration keep you connected and informed without distraction.

Safety technology surrounds you with confidence. Automatic emergency braking, blind spot monitoring, lane keep assist, and rear cross traffic alert work together seamlessly. The surround vision camera system provides complete visibility, while the rear camera mirror gives you added awareness when you need it most.

The bed is equally thoughtful. A spray-on bedliner protects your investment, while the integrated trailer system with tire pressure monitoring and brake controller makes towing straightforward and safe. Recovery hooks and hitch guidance add capability for serious work.
