The 2011 Kia Optima Hybrid—the brand’s first hybrid—borrows the drivetrain found on the 2011 Hyundai Sonata Hybrid: a 2.4-liter engine combined with six-speed automatic transmission, a 30kW electric motor and lightweight lithium polymer batteries to provide total 206 horsepower and 36 mpg in the city and 40 on the highway.
