MAGNETIC RIDE CONTROL ENHANCES ATTRACTION OF SIERRA DENALI By: GMC
– Magnetic ride control is an all-new, exclusive feature on the 2015 GMC Sierra Denali, advancing its position as the most refined and technologically advanced truck on the market. It's the first time the advanced, electronically controlled damping system has been offered on a full-size truck.
Magnetic ride control provides more precise body motion control that correlates with a more refined ride while maintaining payload and trailering capability. It is standard on all Sierra Denali half-ton models, whether equipped with the standard 5.3L V-8 (355 hp) or the available 6.2L V-8 (420 hp) – the segment's most powerful engine.
'With magnetic ride control, the 2015 Sierra Denali delivers a smoother, more confident driving experience without sacrificing the capabilities customers expect from a GMC truck,' said Jeff Luke, executive chief engineer. 'The responsiveness of the system makes this full-size truck feel and drive like a luxury vehicle – and one that's more comfortable on long trips, especially when trailering.'
The 2015 Sierra Denali's maximum payload is 1,940 pounds (4WD with 5.3L and 5'8' box) and the max trailering capacity is 9,400 pounds (2WD with 5.3L or 6.2L and 5'8' box).
The third-generation magnetic ride control's sensors 'read' the road every millisecond, triggering damping changes in as little as five milliseconds in electronically controlled shock absorbers that replace conventional mechanical-valve shocks. They're filled with a magneto-rheological fluid containing minute iron particles, and under the presence of a magnetic charge, the iron particles align to provide damping resistance. Changes in the magnetic charge alter the damping rate of the shocks almost instantly.
Magnetic ride control complements chassis and suspension enhancements introduced across the Sierra 1500 range for 2014:
◾A stronger, fully boxed frame with the main rails and major cross members formed from high-strength steel, providing a rigid base for maximum hauling capability, great noise and vibration isolation and excellent crashworthiness. The stiff chassis enables more precise tuning of the front and rear suspensions, for a more responsive feel with smoother performance and less vibration and shake, particularly on harsh terrain.
◾A wider rear track and half-inch wider wheels improve that stability and ride smoothness. The geometry also contributes to flatter, more confident-feeling cornering, particularly when hauling heavy cargo or towing.
◾An electric variable-assist power steering system enhances handling and reduces steering effort at low speeds. The variable assistance enhances overall handling with reduced steering effort in parking lots and a higher rate on the highway that provides a more solid, direct and on-center feel.

The Sierra Denali – offered exclusively as a crew cab – delivers unique design cues and exclusive features, starting with a signature chrome grille, projector-style headlamps with LED signature daytime running lights, unique 20-inch chrome wheels, a polished stainless steel exhaust outlet and body-color front and rear bumpers.
Denali-specific interior details include script on the bright door sills and embossed into the front seats, and real aluminum trim. The high-tech cabin also features an exclusive eight-inch-diagonal Customizable Driver Display that can show relevant settings, audio and navigation information in the instrument panel, as well as a Bose audio system, heated and cooled leather front bucket seats, a heated steering wheel, front and rear park assist and a power sliding rear window with defogger.
Sierra Denali's standard eight-inch Color Touch navigation radio with IntelliLink, located above the center console, serves as the main hub for Bluetooth-connected phones and portable devices connected through five standard USB ports.
Enhanced connectivity and convenience for 2015 include a new Text Messaging Alerts feature for smartphone users with Bluetooth profile (M.A.P.), which reads incoming texts through the vehicle's speakers, and Siri Eyes Free for iPhone iOS 6 and iOS 7 users. They're voice-controlled to help keep phones safely stowed and hands on the wheel.
Also new is OnStar with 4G LTE and standard built-in Wi-Fi hotspot, providing a mobile hub for drivers and passengers to stay connected. The hotspot is on whenever the vehicle is on and comes with a three-month/3GB data trial.
The Sierra Denali is backed by GMC Pro Grade Protection, with two years of scheduled maintenance, a three-year/36,000-miles bumper-to-bumper warranty and a five-year/100,000-mile powertrain warranty.
A heritage of distinction
As GMC's ultimate expression of its professional grade philosophy and the best of its capabilities, the Denali nameplate has become synonymous with performance, refinement and technology. It represents more than 20 percent of all GMC retail sales and is offered on Terrain, Acadia, Yukon and Sierra models.
All Denali models are distinguished on the exterior by a signature chrome grille and exclusive interior trim. They are also often technology leaders for GMC, with features such as magnetic ride control offered exclusively on Sierra Denali and Yukon Denali.
'Denali has earned a reputation for uncompromising refinement with capability after more than 15 years of premium vehicles that take truck and SUV ownership experiences to higher levels,' said Duncan Aldred, vice president of GMC Sales and Marketing. 'It's a symbol that embodies the finest of GMC's engineering, technology and attention to detail.'
More than 675,000 Denali models have been sold since the introduction of the 1999 Yukon Denali. In fact, Denali models alone outsell the entire product lines of some premium auto brands such as Land Rover, Jaguar and Porsche.
GMC has manufactured trucks since 1902, with innovation and engineering excellence built into all GMC vehicles. The brand is evolving to offer more fuel-efficient trucks and crossovers, including the Terrain small SUV and Acadia crossover. GMC's highest-volume vehicle, the Sierra 1500 pickup, is the most powerful light-duty pickup on the market, and the first full-size pickup to receive the highest-possible five-star Overall Vehicle Score for safety since the National Highway Traffic Safety Administration changed its New Car Assessment Program for the 2011 model year (www.SaferCar.gov).
