The front-wheel-drive 2013 Sonata has a standard 198-horsepower four-cylinder engine and an available 274-horsepower, turbocharged four-cylinder engine. A smooth-shifting six-speed automatic transmission is standard. Some might find the standard engine somewhat anemic for highway passing. In comparison, the turbocharged engine has lots of passing power. The Sonata delivers a comfortable ride that can be adjusted for firmer handling. The base four-cylinder engine has an EPA rating of 24 mpg in the city and 34 mpg on the highway, while the turbocharged engine has an EPA rating of 22/33 mpg city/highway.
