Vehicle Overview

Sleek Onyx Black 2026 SUV for everyday drive

Ready to work hard and turn heads — meet the 2026 AT4 in sleek Black. Built for trail and town, it pairs a true off-road arsenal (full-time 4WD, locking differential, traction/stability control and 4-wheel ABS) with premium comfort: leather-trimmed, heated and cooled front seats, heated leather steering wheel, power sunroof and an intuitive nav/infotainment suite. Convenience and security come standard — keyless entry, remote start with climate control, anti-theft system and an electronic parking aid — plus comprehensive safety (multiple airbags and advanced stability systems). With rugged 20" tires, 10.1" ground clearance and strong factory warranties (36/36 basic, 60/100 powertrain, 72/100 rust), this AT4 is ready for anything. Stop by for a test drive and feel it for yourself.
