Updates include magnetic ride control suspension.
GMC has revealed some minor updates for the 2015 Sierra Denali, the addition of its advanced magnetic ride control (MRC) suspension chief amongst them. Similar to the system used in the Corvette and Cadillac CTS, the 2015 GMC Sierra Denali will be the first full-size pickup to use the electronically-controlled damping system. “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." Other upgrades include Siri Eyes Free compatibility and Text Messaging Alerts, a feature that reads incoming text messages aloud. It also comes with a new OnStar 4G LTE system with built in Wi-Fi hotspot.
