Premium safety features
Four-wheel disc brakes with Duralife brake rotors feature a hardened and strengthened surface to reduce corrosion. The rotors are expected to last longer and provide quieter braking with less vibration.
The 2014 pickups also use electric power steering. An electric motor in place of an engine-driven hydraulic pump saves fuel and allows for tuning that results in a more consistent, crisp steering feel and plenty of assist for parking maneuvers.
The Sierra comes with projector beam headlamps. In addition, a suite of active safety features will be optional, including Forward Collision Alert, which uses a forward-facing camera to notify the driver of an imminent collision, and Lane Departure Warning, which uses the same camera to track the truck’s position in relation to a road’s lane markers.
In addition, the new Driver Alert Seat generates vibrating pulse patterns on the left and/or right side of the lower seat cushion bolster to alert the driver of potential dangers, such as an un-signaled lane change or approaching another vehicle too quickly. According to GM research, the seat’s vibrations may direct driver attention to the location of a potential collision more quickly and accurately than audible alerts.
Updated mirrors that reduce wind turbulence, triple-sealed inlaid doors and roof and tailgate design features all help air flow smoothly and quietly over the Sierra. Additional sealing around the grille, headlights and space between the cab and box also lower drag, along with aerodynamic spats located in front of the rear wheels. As a result, the aerodynamic coefficient of drag is 5% less than current models.
Fuel economy and performance specs have yet to be released for the new models, so stay tuned for further updates. ET
