Spy photographers captured a restyled Hyundai Sonata during hot-weather testing in Death Valley earlier this week. Engineers got up nice and early to catch the test vehicle. While this prototype maintains the current Sonata's styling between the A- and C-pillars, the front and rear fascias have been modified. Redesigned headlights flank a new grille with horizontal chrome bars, and the front bumper has a larger, trapezoidal-shaped lower intake that widens at the bottom for a more stout expression. The new grille brings the styling more in line with the upcoming Genesis luxury car.Heavily camouflaged, changes to the Sonata's rear are less obvious, but it appears that restyled tail lamps with prominent white strips are part of the plan. Judging from the quick drive-by shot of the interior, the Sonata will receive a revised center console and redesigned stereo akin to the Hyundai Veracruz.
