The 2020 Chevrolet Impala is an American made full-size sedan available in two configurations this year. For 2020, the LT trim level now replaces the discontinued LS as the base model Impala. The LT has many standard features and a pair of optional packages. If you require more luxury, upgrade to the Premier model. This is the model that gets you into the leather seats and nicer wheels. Both trims utilize a 3.6-liter V6 (305 horsepower, 264 lb-ft of torque) that sends power to the front wheels via a six-speed automatic transmission.
