2012 Hyundai Sonata Overview The 2012 Hyundai Sonata comes standard with a four-cylinder engine, and test drivers wrote that it has adequate power for passing on the highway. Critics said the optional turbocharged four-cylinder feels strong and has smooth power delivery. However, reviewers said that both engines are noisy during acceleration. The four-cylinder 2012 Hyundai Sonata gets an EPA-estimated 24/35 mpg city/highway, which is very good for the class. The turbocharged model gets 22/34, which is much better than V6-equipped competitors with similar horsepower ratings. Test drivers wrote that the Sonata’s ride is comfortable, with only the largest bumps making it through to passengers. Though some critics complained about the Sonata’s numb steering system, most said that the Sonata’s handling is fine for an affordable midsize car. Reviewers noted that the 2012 Sonata’s interior has a modern design that’s built with class-appropriate materials that include soft plastics and silver trim. Test drivers wrote that the front seats are comfortable, and that the rear seats have plenty of legroom for 6-foot passengers. At 16.4 feet, the Sonata’s trunk is quite large for the class. The Hyundai Sonata comes standard with Bluetooth, a USB port and satellite radio, heated side mirrors, a six-speaker audio system and Hyundai’s Blue Link telematics system. Available features include a sunroof, leather upholstery, heated front and rear seats, navigation and a nine-speaker Infinity audio system.
