2018 Chevrolet Tahoe: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for the 2018 Chevrolet Tahoe is the introduction of the RST package. This is a light update rather than a redesign, and the Tahoe’s basic V8-powered, three-row formula carries over.
About the 2018 Chevrolet Tahoe
4th generation (2015-2020), fourth model year; a late-cycle update year before the lightly changed 2019 model.
Chevrolet positions the Tahoe as a full-size SUV for people who need real towing strength, three-row passenger space and truck-based durability without moving up to an even larger Suburban. Its core appeal is straightforward: V8 power, a high seating position, a roomy cabin and cargo area, and a trim ladder that runs from work-focused fleet use to near-luxury comfort. Compared with crossover SUVs, the Tahoe leans harder into capability and size.
The 2018 Tahoe ranges from the work-focused Commercial model and practical LS to the more comfortable LT and upscale Premier. LS has an 8-inch touchscreen with Apple CarPlay and Android Auto, LT adds leather-appointed heated front seats and a power liftgate, and Premier brings navigation, ventilated front seats, Magnetic Ride Control for a smoother ride, and blind-spot monitoring.

Tech
Commercial gained an 8-inch touchscreen, HD Radio, a 4.2-inch color driver display, and steering-wheel audio and cruise controls. LS gained an 8-inch touchscreen with Apple CarPlay and Android Auto.
Safety
