If there's a single vehicle that distinguishes the new Hyundai from the old, it's the current-generation Sonata sedan. The redesigned Sonata debuted for the 2006 model year with relevant styling, class-competitive powertrains and a new feeling of refinement, along with every bit of the price-feature value that once was Hyundai's sole reason for being. Over the next couple years, though, the Sonata would begin losing ground in the segment as many of its best-selling competitors underwent complete redesigns. The sedan's passenger cabin became the greatest area of need, having been left far behind the competition in both styling and features. In updating its top-seller for the 2009 model year, Hyundai has certainly given the Sonata the attention it needed to be a true segment player.
