2014-2021

The Chevrolet Impala from 2014 to 2021 represented a modern interpretation of a classic American sedan. It retained its full-size stature, offering spacious and comfortable seating for up to five passengers. The exterior design evolved to showcase a sleek and contemporary look, and the interior received substantial updates with higher-quality materials and advanced technology features. These Impalas came equipped with a range of amenities, including touchscreen infotainment systems, advanced safety features like forward collision warning and lane departure warning, and available leather upholstery for a more premium feel. While the focus remained on comfort and practicality, the Impala’s suspension tuning balanced a comfortable ride and decent handling. Although the market shifted towards SUVs and crossovers during this period, the Impala continued to appeal to buyers seeking a traditional, comfortable, and spacious sedan option. However, Chevrolet discontinued the Impala after the 2020 model year, marking this iconic nameplate’s end of an era.
