During low-speed towing maneuvers, such as backing into a boat launch orparking a camper, White says, Quadrasteer also greatly improves the trailer response to steering input.
White says the system operates in three ways: at lower speeds, the rear wheels turn in the opposite direction of the front wheels; at moderate speeds, the rear wheels remain straight; and at higher speeds, the rear wheels turn in the same direction as the front wheels.
"In real world terms, this innovative technology provides full-size truck drivers the agility of a smaller truck or passenger car, allowing the driver to turn tightly at low speeds," White maintains.
He says, "Four-wheel steering is one of the many innovative technologies and features within GM's full-size truck portfolio intended to provide customers with real benefits while reinforcing brand equity."
Other innovative technologies and features already available only on GMfull-size truck products, says White, would include a three-piece modular frame, driver message center, dynamic rear brake proportioning, Autotrac active 4x4 transfer case, Tow/Haul mode, Oil Life Monitoring System, and (on various SUVs) a 5-link rear suspension, self-leveling rear shocks, Autoride suspension system, 2WD traction control, and a light weight aluminum rear liftgate.
