Hyundai made that announcement at the Detroit Auto Show this morning, saying that 22 miles is "farther than any other midsize PHEV sedan." Those zero-emission miles will come from a 9.8-kWh lithium polymer battery and a 50-kW electric motor. Once the pack runs out, Hyundai expects the PHEV to get 40 mpg combined (as well as 38 mpg city and 43 mpg highway) thanks to the gas-powered heart of the powertrain: a 154-horsepower, 2.0-liter Nu GDI four-cylinder engine that puts out 140 pound-feet of torque. When combined with the motor, the total system output is 202 horsepower.
Hyundai is also showing off a non-plug Sonata Hybrid, which is expected to get a 10-percent fuel economy boost. The current version gets 38 mpg, combined, so that hints at around 42 mpg on the sticker when the car arrives in dealerships. The plugless model has to make due with a 51-hp, 38-kW electric motor that offers 151 pound-feet of torque and a net power rating of 193 horsepower.
The two new Sonata Hybrid models have their own, more aerodynamic front and rear fascias as well as "purposefully unique wheels" that help drop the drag coefficient to just 0.24. The PHEV has a unique grille and a charge port on the front driver's side. Both models will arrive in dealerships later this year.
