2015 Sonata Hybrid

The Sonata Hybrid is the efficiency-minded, gasoline-electric version of Hyundai's popular midsize sedan. It offers a high level of content in a stylish wrapper, and for the first time, offers class-competitive fuel economy in the hybrid segment.

Recent Changes

The Sonata Hybrid and Plug-in Hybrid models have been updated with a new look to match the regular Sonata sedan's.


Most hybrids are all about fuel economy, and the Sonata Hybrid is no exception to the rule. However, it goes about its high-mileage mission in a slightly different manner than most other gas-electric vehicles, giving it a unique set of strengths and weaknesses that should be fully considered by prospective buyers.

While nearly all other hybrid vehicles are thriftier in the city than on the highway, Hyundai specifically designed the Sonata Hybrid for maximum freeway mpgs. It returns 40 mpg in the city and 44 mpg on the highway, meaning the sedan could be a good fit for those who spend a great deal of time on the open road.

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 193 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 56 kW battery pack is capable of powering the Sonata Hybrid up to a top speed of 75 mph without the aid of the gasoline engine, however its range in electric mode is limited.

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 as in the normal Hybrid.

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.

Additionally, the Sonata now comes standard with Android Auto and Apple CarPlay, which allows the driver make calls, use maps, listen to music and access messages all on the car's seven-inch touch screen infotainment system (an eight-inch unit is option on top-spec cars).

Trim Level Breakdown

Both the Sonata Hybrid and Sonata Plug-in Hybrid are available in two trim levels: SE (base) and Limited.
