The 2016 Hyundai Sonata Plug-in Hybrid Electric Vehicle with a 9.8 kWh lithium polymer battery pack, roughly five times larger than the Sonata Hybrid’s battery, is expected to give Sonata Plug-in Hybrid an all-electric range of up to 22 miles and can recharge in as little as two and a half hours with a Level 2 charger. Sonata PHEV’s Nu engine produces 154 horsepower and 140 lb. ft. of torque and the total system output is 202 horsepower at 6,000 rpm. Sonata Plug-in Hybrid uses a six-speed automatic transmission with Hyundai’s Transmission-Mounted Electrical Device, a 50 kW electric motor, in place of a torque converter. The 50 kW electric motor is 32 percent more powerful than the motor used the in regular Sonata Hybrid and allows EV operation at higher speeds. A 2.0-liter Nu four-cylinder GDI engine coupled with the electric motor allows the Sonata Plug-in Hybrid to operate just like the Sonata Hybrid once the onboard battery charge is depleted.
Sonata PHEV is expected to deliver 93 MPGe combined in EV mode based on internal estimates. In charge sustaining mode, the Sonata PHEV is expected to return 38 mpg in the city, 43 mpg on the highway and 40 mpg combined based on internal testing. The Sonata Plug-in Hybrid will be available in California, Connecticut, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Rhode Island and Vermont in 2015.
