Vehicle Overview

Bold, capable SUV with everyday comfort

Introducing the 2026 AT4 — dressed in striking Black and built to work as hard as it wows. This truck pairs serious off‑road capability (4WD, locking differential, traction & stability control, LT305/70R18 tires and a full‑size spare) with premium comfort and tech. Inside you’ll find leather heated and cooled front seats with power lumbar and multi‑adjustability, a heated leather steering wheel, power sunroof, navigation and a rich subwoofer audio system. Convenience is effortless with keyless entry, remote ignition with climate control and a full suite of safety features — ABS, multiple airbags and vehicle anti‑theft protection. Backed by solid coverage (36/36k basic, 60/100k powertrain, 72/100k rust), the 2026 AT4 is ready for the job site, the trail and a comfortable commute. Ready to see it in person? Let’s schedule a test drive.
