After receiving significant upgrades last year, the Sonata receives only minor changes this year. Among these are a battery-saver feature (in the event that any of lights are left on); illuminated window switches; a 12-volt power point in the trunk; and electronic, rather than cable-operated, releases for the trunk lid and fuel door. Additionally, Hyundai announced that it had misstated the horsepower ratings for all of the models in its lineup in previous years, so the Sonata's four-cylinder is now rated at 138 horsepower (down from 149) and its V6 is rated at 170 (down from 181), though the engines themselves are unchanged.
