Vehicle Overview

Coastal Dune GMC AT4: Rugged yet refined SUV

Meet the 2026 AT4 — the perfect blend of rugged capability and refined comfort. Standard 4WD with locking differential, ABS, traction and stability control means confident performance on whatever terrain you tackle, and an advanced vehicle anti-theft system adds real peace of mind. Inside you’ll find heated/cooled leather power seats with lumbar, a heated leather steering wheel, power sunroof, navigation and a premium subwoofer — plus keyless entry and remote start with climate control for instant comfort. Practical extras like a full‑size spare, automatic headlights and heated mirrors, backed by factory warranties (3yr/36k basic, 5yr/60k powertrain, 6yr/100k rust), make the AT4 as dependable as it is capable. Schedule a test drive and experience it for yourself.
