For 2013, Hyundai Sonata Hybrid increases fuel efficiency and operate in all electric modes more often and for longer periods of time, with an advanced version of the brand’s Hybrid Blue Drive architecture. The improved architecture optimizes electric only driving with a higher output 35 kW electric motor, a more powerful 47 kW Lithium Polymer battery pack and an optimized hybrid operating strategy. These upgrades are paired with a 2.4-liter Theta II four cylinder engine that now runs on a more efficient Atkinson cycle and an enhanced transmission to generate 199 combined net horsepower.
