The Tahoe received 4G LTE, WiFi, and Siri capability, a new color palette, Brownstone Metallic, and added a hands-free power liftgate feature that is standard on LTZ, but included on LT with the optional Luxury Package. The MyLink with Navigation feature became standard on the LTZ trim, while E85 capability is removed from retail orders.
The Yukon, in addition to receiving the aforementioned features, sees the 6.2-liter EcoTec3 V8 engine being updated with the new 8L90E eight-speed automatic transmission for the interim model year, allowing it to improve fuel economy.
