Inside, the Denali Ultimate cabin reflects meticulous attention to comfort and technology. Full grain leather, genuine wood dashboard and door panel inserts, and a heated steering wheel create an upscale environment. The 16-way adjustable power seats with lumbar support accommodate long drives, while the ventilated front seats and heated rear outboard seats adjust to changing conditions. Wireless phone projection and charging keep your devices connected throughout the day.
Safety and convenience technology are comprehensively integrated. Automatic emergency braking, forward collision alert, and lane departure warning help protect occupants.

Trailer-specific features including the hitch guidance system, in-vehicle trailering app, and trailer tire pressure monitor sensors demonstrate GMC's commitment to trailering excellence.

The hitch platform accepts either configuration, stamped bed holes with removable caps are installed, and the bed-mounted 7-pin trailer harness connects easily. This foundation supports ambitious towing plans without compromise.
