The 2021 Sonata is available with four different powertrains. The base engine in the SE and SEL is a 2.5-liter, naturally aspirated four-cylinder making 191 horsepower and 181 pound-feet of torque. These figures are typical for entry-level engines in the midsize segment. This engine is rated at 28 mpg city, 38 mpg highway and 32 mpg combined in the SE model and 27/37/31 in the SEL. Stepping up to the SEL Plus and Limited models means switching to the 1.6-liter turbocharged four-cylinder. This engine produces less power (180 horses) than the base 2.5, but more torque (195 lb-ft). It likewise offers similar numbers to other lower-end turbocharged engines offered by the competition, such as the Honda Accord’s 1.5-liter. It even offers more power from a smaller package than the 2.0-liter turbo offered in the Volkswagen Passat. This engine is rated at 27 mpg city, 37 highway and 30 combined.
