As its name suggests, the 2017 Hyundai Sonata Plug-in Hybrid sedan can be plugged into an electrical outlet or charging station to charge its lithium-ion battery pack. That battery is five times larger than the one in the automaker's regular Sonata Hybrid, giving the Sonata Plug-in Hybrid's upsized electric motor the ability to propel this midsize sedan up to 27 miles in all-electric mode.
The advantage should be obvious. There's none of the range anxiety experienced by drivers of all-electric vehicles because once the battery's charge is depleted, the Sonata's internal combustion engine comes online and the car operates as a normal gasoline-electric hybrid. The result is 99 miles per gallon equivalent when you figure in the all-electric range and a solid 39 mpg in traditional hybrid mode. Besides its powertrain, the Sonata Plug-in Hybrid offers the same traits as the regular Sonata, such as a roomy interior, a pleasant driving demeanor and a long list of standard features. Overall, the 2017 Hyundai Sonata Plug-in Hybrid's combination of plug-in capability and traditional midsize sedan strengths makes a solid pick.
- Above-average all-electric plug-in range
- Spacious interior with comfortable front seats
- User-friendly infotainment interface
- Not as much cargo space as hatchback competitors
- Grabby brake-pedal feel can make it hard to stop smoothly
