The Optima is available in four trim levels; LX, EX, EX Turbo and SX. The LX and EX are equipped with a naturally-aspirated 200-hp 2.4-liter DOHC four-cylinder. The EX turbo and SX use a turbocharged 274-hp 2.0-liter four-cylinder. A six-speed manual transmission is standard on the LX, while a Sportmatic six-speed automatic is available on the LX and standard on all other trims. Standard safety features include active headrests, traction-control, stability-control, four-wheel antilock brakes and a tire pressure monitor. The Optima has been completely redesigned for 2011. Striking new sheet metal envelopes an all-new interior design. Features such as Bluetooth, power driver lumbar, dual illuminated vanity mirrors and a cooled glovebox are now standard on all trims.
