GM Sierra Trailering Tech Enhances Safety and Performance

Advanced systems complement class-leading trailering capability

DETROIT – Six in 10 full-size pickup owners use their trucks for trailering, according to General Motors’ survey data. Along with class-leading trailing capacities, the all-new 2014 GMC Sierra 1500 offers that majority of customers a full suite of trailering technologies that aid everything from acceleration to safety and braking.

“Trailering is a fundamental capability that customers invest in and depend on when they purchase a truck,” said Tony DiSalle, vice president of GMC Marketing. “The 2014 Sierra backs up its unmatched capability with a host of ingenious driver aids.”

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

With Tow/Haul mode engaged, Sierra’s Trailer Grade Braking is activated when the driver lightly applies the brakes. This feature initiates downshifts to assist with braking on long downgrades. In addition to slowing the vehicle more efficiently, Auto Grade Braking can reduce brake rotor temperatures by 100 degrees Celsius during a braking event.

For drivers who prefer full control over their truck’s shifting, improved TapShift controls on the shift lever are backed by a patent-pending shift algorithm that improves shift response time by up to 60 percent compared to previous systems. When the TapShift controls are in use, Sierra’s Trailer Grade Braking is deactivated because the driver is manually controlling gearshifts.
