The Chevrolet Impala lineup starts with LS for straightforward full-size comfort, while LS Eco adds a mileage-focused mild-hybrid angle. LT is the mainstream comfort and convenience step, with LT Eco carrying that idea into the Eco branch; SS is the V8-powered sport sedan; LTZ and Premier are the upscale choices; and LS CNG and LT CNG are factory bi-fuel models that run on compressed natural gas or gasoline.

The LS is the straightforward entry trim on Impalas built before it was dropped for 2020. On later tenth-generation cars, it focuses on the model’s roomy cabin and everyday basics, with equipment such as a power driver seat and split-folding rear seat.
The LT is the mainstream Impala trim. On newer models, it combines the roomy cabin with useful comfort and phone-friendly technology. In the final lineup, it had a V6, an 8-inch touchscreen, dual-zone climate control, remote start, and a power driver seat.
Premier is the upscale trim used in the later tenth-generation lineup. It builds on the Impala’s space and comfort with leather seating, heated front seats, built-in navigation, Bose audio, wireless charging, and added parking and blind-spot alerts.
They fill the same top-trim role in different eras. Chevrolet renamed LTZ to Premier for 2017. Both emphasize leather, stronger comfort equipment, and added driver-assistance features, but the exact items differ by model year.
On the final-generation cars, Premier adds a more upscale cabin and more assistance features. Key upgrades include leather seating, heated front seats, navigation, Bose audio, wireless charging, blind-spot monitoring, rear cross-traffic alert, and rear parking sensors.
The LT generally adds convenience and cabin upgrades over the LS, though details vary by year. On later cars, LT equipment includes dual-zone automatic climate control and remote start. Some earlier LS and LT models also differ in touchscreen size, trim materials, and engine.
The LT Eco is the better-equipped mild-hybrid version. Both use the 2.4-liter eAssist powertrain and airflow-focused hardware, while LT Eco adds the 8-inch touchscreen, Bluetooth audio streaming, and leather wrapping for the steering wheel and shifter.
The Eco trims focus on lower fuel use rather than stronger performance. The 2014 LS Eco and LT Eco use a 2.4-liter eAssist mild-hybrid four-cylinder, active grille shutters, and Eco-specific displays. Regular trims from that era use conventional gasoline engines.
The 2009 SS is the performance-focused Impala. It pairs the roomy front-wheel-drive sedan body with a 5.3-liter V8, firmer suspension tuning, heated leather-appointed front seats, 18-inch polished wheels, and brighter dual exhaust outlets.
Look first at LS on earlier cars or LT on the final 2020 lineup. LS keeps the equipment simpler while retaining the Impala’s roomy cabin. LT became the entry trim for 2020 and includes the V6, touchscreen, dual-zone climate control, and remote start.
Premier or the earlier LTZ is the comfort-focused pick. These top trims add items such as leather, heated front seats, extra driver-assistance features, and richer cabin equipment. On later Premier models, navigation and Bose audio also suit frequent highway travel.
Choose LT for the core Impala experience with fewer upscale extras. Choose LTZ on pre-2017 cars for leather, heated front seats, a V6, and added alerts such as forward-collision, lane-departure, blind-spot, and rear cross-traffic warnings.
The 2015 and 2016 LS CNG and LT CNG are factory bi-fuel models. Their 3.6-liter V6 runs on compressed natural gas or gasoline, and the driver selects the fuel mode from inside the car. These trims use front-wheel drive and a six-speed automatic.
The LT CNG has the richer cabin and more convenience equipment. Compared with LS CNG, it adds an 8-inch touchscreen, remote start, dual-zone automatic climate control, a rear camera, rear parking sensors, and leather wrapping for the steering wheel and shifter.
