The 2015 Chevrolet Tahoe and Suburban models will be offered with the Z71 package in the US to enhance off-road capability.
The Chevrolet Z71 kit adds front skid plate, off-road tires mounted on 18-inch wheels, a unique grille, running boards and “Z71” identification inside and out. To cope with difficult terrain, the Z71 pack includes automatic locking rear differential that provides greater traction when needed.
It also comes with third-generation magnetic ride control – a real-time damping system that delivers more precise body motion control.  Tahoe Z71 and Suburban Z71 customers will find fog lamps, front tow hooks and front parking assist on the equipment list.
Inside the cabin, technology blends with the classic interior lines. The two cars offer optional wireless phone charging feature, a magnetic inductive charging system that is very easy to use. OnStar with 4G LTE and built-in Wi-Fi hotspot is standard on LT and LTZ models. It provides a mobile hub for drivers and passengers to stay connected.
