This system allows the driver to adjust the ride height for functional purposes, such as optimizing aerodynamic efficiency on the highway or increasing ground clearance when navigating obstacles off-road.
Drive Modes
The truck features customizable drive modes to tailor performance characteristics (accelerator responsiveness, suspension tuning, steering feel, motor sound) to specific conditions:
Normal
Tow/Haul
Off-Road
Terrain (specific to AT4)
My Mode (user-personalized settings)
Cargo Management Systems
The Sierra EV incorporates advanced solutions for cargo versatility:
MultiPro Midgate: An available system that extends the usable cargo length by folding the rear seats and removing a modular glass panel from the rear cab wall. This allows for class-leading cargo lengths up to 10 feet 10 inches when combined with the load stop function of the tailgate.
eTrunk: A lockable, weatherproof storage compartment located under the hood (frunk), providing secure storage for luggage or gear.
MultiPro Tailgate: A six-function tailgate that can be configured in various positions to improve loading, unloading, and access to the cargo box.
