For the 2013 model year Kia has decided to make a few updates to its Optima Hybrid model which has been fitted with a more powerful Hybrid Starter Generator, just like the 2013 Hyundai Sonata Hybrid. In addition, the lithium polymer battery has also been improved, while the beefier electric motor is now capable of delivering 47 hp (35 kW). As a result of this power boost, the 2013 Kia Optima Hybrid is rated with a 199 hp (148 kW) and 318 Nm (235 lb-ft) combined output, while its predecessor offered 206 hp (154 kW) and 264 Nm (195 lb-ft) of torque. Fuel economy is also up to 36 mpg in the city, 40 mpg on the highway and 38 mpg in the combined cycle.
Aside from the improvements made to the powertrain, the revised Optima Hybrid also benefits from new aluminum suspension components, a new look for the alloys, better underbody aerodynamics, reduced ride height and a rear spoiler. It also benefits from a more spacious trunk, while the new EX model brings heated and ventilated front seats, panoramic sunroof, 8-speaker Infinity audio system and GPS navigation.
