The 2020 Impala is powered by one engine choice, a 3.6L V6 making 305 horsepower and 264 lb-ft of torque mated to a 6-speed automatic transmission. Chevrolet claims that the Impala's 6-cylinder engine is the most powerful naturally aspirated V6 in its class. The Impala comes in two trims: LT and Premier.
