The Sonata Plug-In Hybrid is the upgrade to Hyundai's efficiency-minded, gasoline-electric version of its popular midsize Sonata sedan. It offers a high level of content in a stylish wrapper.

Recent Changes

The Sonata Plug-in Hybrid is a brand-new entry from Hyundai. A traditional hybrid is also available.


The Sonata Hybrid is motivated by a direct-injected 2.0-liter four-cylinder gasoline-burning engine linked to an electric motor. The system produces a combined 202 horsepower and an unspecified amount of torque. On paper, the figure should be north of 200lb-ft. The electric motor alone produces 151lb-ft and the gas engine contributes another 140. Due to the way the parallel hybrid system is designed, the two would not be delivering their maximum torque output simultaneously, so those values cannot simply be added together.

The Plug-in model packs a beefier battery pack with a 68-kW capacity. It is capable of powering the Sonata for up to 27 miles without gasoline engine intervention. Electric mode is capped at 75 miles per hour.

Most hybrids are all about fuel economy, and the Sonata Hybrid is no exception to the rule. As a plug-in model, it also plays in the electric vehicle space and carries an MPGe rating in addition to its standard hybrid ratings. The powertrain is rated at 40 MPG combined or 99 MPGe in EV mode.

On standard 110/120V power, charging takes just under 9 hours. A level 2 charger is available and cuts the total charging time to less than three hours.

Life Aboard

Inside, the sedan features a shapely dashboard that echoes the exterior design and a special instrument cluster with eco-display options that helps the driver achieve the highest possible gas mileage.

The Sonata Hybrid is offered with Hyundai's Blue Link telematics service, which can be spec'd to provide voice text messaging, point-of-interest web search and download, and automatic collision notification in addition to traffic, weather, restaurant and nearby gas station information. A dedicated application can transform a compatible smartphone into a remote control that can be used to turn the car on and off, turn on the rear defroster or set the climate control settings, functions that owners in cold climates will be sure to appreciate.

The Sonata Hybrid offers seating for up to five passengers and 13.3 cubic feet of cargo space.

Trim Level Breakdown

The Sonata Plug-in Hybrid is available in two trim levels: SE (base) and Limited. There are no packages available.

Key Competitors

The Sonata Plug-In Hybrid can be cross-shopped against a large number of gasoline-electric mid-sizers, some of which are available as plug-ins and some not.
