Hyundai has quietly unveiled the 2012 Sonata facelift in South Korea. The updates includes a revamped front grille with less chrome on top and around the sides, reshaped mirror casings, new LED taillights and a choice of 18-inch multispoke alloy wheels. The interior has been slightly tweaked and features new trim options and higher quality materials. Under the hood, the Sonata will generate power from a 2.0-liter four-cylinder with 165hp that's mated to a manual or automatic transmission.
