2018 Chevrolet Impala: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for the 2018 Chevrolet Impala is a broad standard-equipment upgrade across the lineup. It is not a redesign, but every trim gains useful features, led by standard keyless open and push-button start.
About the 2018 Chevrolet Impala
10th generation (2014-2020), fifth model year.
The 2018 Impala is Chevrolet’s full-size sedan for shoppers who want space, comfort, and an easy highway-driving character. Chevrolet sold it as the roomy, quiet alternative to smaller family sedans, with adult-sized rear-seat space, a large trunk, and straightforward touchscreen tech. Its identity is less about sharp handling and more about relaxed commuting and long-distance comfort, especially for drivers who want near-upscale cabin room without moving to a luxury brand.
The LS is the value-focused trim, with an 8-inch touchscreen, Apple CarPlay, Android Auto and upgraded cloth and synthetic leather upholstery. The LT emphasizes comfort with dual-zone climate control, remote start and LED daytime running lights. Premier is the luxury-oriented version, pairing a 3.6-liter V6 with leather-trimmed comfort, navigation, Bose audio, wireless phone charging and added driver-assistance features.

“If you really want wireless cell phone charging don't buy this vehicle. There are very few phones that work with this feature. Other brands have a much better system that works with all phones by just placing them on the charging plate.”
“Great ride, great room and comfort. I love the full size space with a 6 cylinder engine. It is a delight to own.”
