The 2013 Kia Optima is one of our top picks for a midsize sedan. With evocative styling, strong engine choices and a long list of features, it's easy to see why. The Optima is powered by a 2.0-liter turbocharged four-cylinder engine that produces 274 hp and 269 lb-ft of torque. A six-speed automatic transmission is standard. The gas-powered Optima EX trim adds eight-way power driver seat, driver lumbar adjustment and an auto-dimming rearview mirror, dual-zone automatic climate control, an eight-speaker Infinity audio system, HD radio, and a rearview camera. 17-inch wheels, keyless ignition/entry, automatic climate control, rear air vents, leather upholstery, a leather-wrapped steering wheel and shifter, upgraded dash trim and floor mats.
