2015 GMC Sierra 1500 Denali Gets Magnetic Shocks
Top-Line Truck Gets High-Tech Dampers
Since it was introduced in 2007, the GMC Sierra Denali has established itself as the definitive luxury fullsize truck. There are now a lot more competitors in the form of the Ram Laramie Longhorn, the Ford F-150 Platinum and Limited, and even GM’s own Chevrolet Silverado High Country. The 2014 redesign of the Sierra brought a whole new level of refinement to the Denali, but in the cutthroat fullsize truck sector, you've got to stay on top of your game, and for the new model year, the 2015 GMC Sierra Denali 1500 gets GM's magnetic ride control.
The claimed benefits of the new shocks are more precise body control and a more refined ride, while maintaining payload and towing capability. The shocks, filled with tiny iron particles, react to a magnetic charge applied to them and can change the damping level in as little as five milliseconds. In addition to the new shock absorbers, the 2015 Sierra Denali also gets the capability to read incoming text messages, iPhone Siri Eyes-Free integration, and optional OnStar 4G LTE mobile data hotspot service. The 2015 Sierra Denali comes standard with a 355hp 5.3L EcoTec3 V-8, with a 420hp 6.2L EcoTec3 V-8 optional.
