The 2016 Hyundai Sonata Hybrid with a downsized 154 horsepower 2.0-liter Nu GDI four-cylinder engine paired with a six-speed automatic transmission that houses a more powerful 38 kW electric motor is expected to achieve up to 39 mpg in the city, 44 mpg on the highway and have a combined EPA rating of 42 mpg, which is more than a 10 percent improvement from the 2015 model. The lithium-polymer battery pack capacity is 1.62 kWh, a 13 percent improvement, and the battery pack now fits under the trunk floor. It's possible for Sonata Hybrid to operate solely on electric power at speeds up to 75 mph by decoupling the gasoline engine from the rest of the drivetrain. Sonata Hybrid will be built at Hyundai’s Asan, South Korea assembly plant and will go on sale early this Summer.
