DETROIT – Six in 10 full-size pickup owners use their trucks for trailering, according to General Motors’ consult data. Along with class-leading trailing capacities, a all-new 2014 GMC Sierra 1500, offers that infancy of business a full apartment of trailering technologies that support all from acceleration to reserve and braking.

“When it comes to trucks, trailering is an essential capability that a business deposit in and count on for work and play,” pronounced Marc Comeau, clamp boss of sales, use and selling for GMC in Canada. “The new 2014 Sierra delivers unmatched capability and a prolonged list of modernized technology, including a Ecotec3 family of engines and GMC’s IntelliLink infotainment system.”

Before a 2014 Sierra is even in motion, systems are monitoring conditions and scheming a lorry to perform. On any class of about 5 percent or higher, Hill Start Assist automatically engages a Sierra’s brakes for 1.5 seconds or until a gas pedal is pressed. This keeps a lorry from rolling rearward and helps in trailering situations like climbing a vessel launch.

Tow/Haul mode, activated by a symbol on a change lever, modifies a customary six-speed transmission’s change mapping to take full advantage of a Sierra’s absolute new EcoTec3 engines. Under acceleration, change points are aloft for some-more power, while downshifts are instituted progressing to foster engine braking, shortening wear on a Sierra’s front brakes.

With Tow/Haul mode engaged, Sierra’s Trailer Grade Braking is activated when a motorist easily relates a brakes. This underline triggers downshifts to support with braking on prolonged downgrades. In further to negligence a car some-more efficiently, Auto Grade Braking can revoke stop rotor temperatures by 100 degrees Celsius during a braking event.

For drivers who cite full control over their truck’s shifting, softened TapShift controls on a change push are corroborated by a patent-pending change algorithm that improves change response time by adult to 60 percent compared to prior systems. When a TapShift controls are in use, Sierra’s Trailer Grade Braking is deactivated given a motorist is manually determining gearshifts.

Trailer Sway Control works with a Sierra’s customary StabiliTrak to yield a motorist with additional assistance when towing a trailer. When it senses trailer sway, it intervenes with braking and/or reduced engine energy to move a trailer underneath control and keep it on a dictated path. It also uses a electric trailer brakes when a trailer is plugged into a customary wiring strap of a truck. 

Sierra owners can also excellent balance a trailer’s braking opening right from a driver’s seat. With an accessible high-mounted Integrated Trailer Brake Controller, a motorist can adjust benefit – a turn of outlay to a electric trailer brakes – around buttons to a left of a steering wheel. System information is displayed in a Driver Information Center on a instrument cluster.

The Trailer Brake Controller allows owners to fast cgange trailer braking force formed on a weight of a trailer. For example, a motorist delivering complicated building reserve could adjust a controller to reduce trailer benefit for an dull trailer on a lapse trip, minimizing a possibility of trailer circle lock-up.
