The 2017 Chevrolet Impala is offered in three main trim levels: LS, LT and Premier. (Chevy also offers versions of the LS and LT with a bi-fuel V6 engine that can run on regular gasoline and compressed natural gas (CNG). You'll unlikely encounter an LS or LT CNG on dealer lots or in online inventory, but note that feature availability does vary slightly compared to the regular versions.) Starting off with an Impala LS gets you a four-cylinder engine, 18-inch steel wheels, automatic headlights, cruise control, air-conditioning, an eight-way power-adjustable driver seat (with power lumbar), a tilt-and-telescoping steering wheel, a trip computer, OnStar (with a 4G connection and WiFi hotspot), Bluetooth phone connectivity and a six-speaker sound system with satellite radio, a USB port, an auxiliary audio jack and a 4.2-inch color display. The Impala's dynamic, modern exterior writes checks that its interior is pleased to cash. The graceful dual-cowl dashboard flows organically into the door panels, creating a wraparound effect that has become a GM trademark as of late. The 8-inch MyLink touchscreen for audio, navigation and phone functions ties it all together with its crisp, high-resolution graphics and an intuitive interface. Apple CarPlay and Android Auto smartphone integration also come standard, and both are great for minimizing driver distraction. It's a worthwhile upgrade compared to the LS's base setup. We would ask only for quicker and more predictable responses to touch inputs, as well as upgraded materials to replace a few flimsy plastic elements in the center console.
