The Optima Hybrid uses the Hyundai Sonata Hybrid powertrain, combining a 2.4-liter MPI engine with a six-speed automatic transmission, and a 30kW electric motor and lightweight lithium polymer batteries to produce a full gasoline-electric hybrid with an estimated fuel consumption of 37 mpg ‑US (6.4 L/100 km; 44 mpg ‑imp) city and 39 mpg ...
