Summary: The midsize Sonata is Hyundai's best-selling vehicle, and for good reason. It offers a smooth ride, a generous interior, competitive engines, and copious features for a relatively low price. The Hyundai Sonata has grown over the years, and is now sized right in line with competitors like the Nissan Altima, Chevrolet Malibu and Toyota Camry. It's no sport sedan, but much like the Camry, the Hyundai Sonata aims at smoothness and luxury over sportiness.
