Which Sonata Plug-in Hybrid does Edmunds recommend?

The base Sonata Plug-in Hybrid comes with a generous number of standard features that will likely satisfy most shoppers. You get a lot of comfort and convenience items with the Limited trim, as well as more advanced safety features, but the $5,600 jump in price may be difficult to justify.

Edmunds' Expert Review

Overall rating

When it comes to plug-in hybrid vehicles, fuel efficiency and electric-only range are vitally important. Unfortunately for the 2018 Hyundai Sonata Plug-in Hybrid, those are some of its weak points. With an electric-only range of 28 miles and EPA-estimated 39 mpg combined rating, it's well below what alternatives such as the Honda Clarity Plug-in, Toyota Prius Prime and Chevrolet Volt deliver.

The Sonata may gain favor with shoppers seeking a more traditional-looking sedan, though, and we like its easy-to-use tech. This year the styling gets a refresh to match the rest of the Sonata lineup and gains more advanced safety features and interior conveniences. Combined with Hyundai's generous warranty, it certainly has its appeal, but those probably aren't enough to overcome its efficiency shortcomings.

2018 Hyundai Sonata Plug-in Hybrid configurations

The 2018 Hyundai Sonata Plug-in Hybrid is a midsize family sedan offered in two trim levels: base and Limited. Under the hood is 2.0-liter four-cylinder engine paired with a 50-kilowatt (67-horsepower) electric motor. Total system output is 202 horsepower, delivered to the front wheels by way of a six-speed automatic transmission. It has an EPA-estimated EV range of 28 miles on a full charge.

Standard base model features include 17-inch alloy wheels, automatic headlights, heated mirrors, a hands-free trunklid, keyless ignition and entry, dual-zone automatic climate control, heated front seats, an eight-way power driver seat, a manual height-adjustable passenger seat, a leather-wrapped steering wheel, an auto-dimming rearview mirror, a rearview camera, blind-spot and rear cross-traffic warning systems, Hyundai's Blue Link emergency communications, Bluetooth, Apple CarPlay and Android Auto smartphone app integration, a 7-inch touchscreen and a seven-speaker sound system with satellite and HD radio, and two USB ports (one front, one charge-only in the rear).

If you are looking for more, though, step up to the Limited. You'll get adaptive LED headlights, rear parking sensors, adaptive cruise control, leather upholstery, ventilated front seats, a power front passenger seat, a heated steering wheel, driver-seat memory functions, a wireless charging pad, an 8-inch touchscreen, a navigation system and an upgraded nine-speaker Infinity sound system. The Limited also comes with forward collision warning, automatic emergency braking, lane keeping assist, a drowsy driver warning system, and automatic high beams.


The Plug-in accelerates to 60 mph in 7.9 seconds, which is average for a hybrid sedan. We like the six-speed automatic transmission since it provides a more traditional shifting experience than a CVT. Less impressive is the grabby feel of the Sonata Hybrid's brake pedal.


The Plug-in Hybrid's ride is smooth on all manner of pavement, and the cabin is quiet at highway speeds. This is a car that will get you to your destination without wearing you out. It's not an exciting car to drive, certainly, but the Sonata Hybrid heads where you point it.


The Plug-in Hybrid's cabin is roomy and comfortable. The seats are supportive and nicely padded, and the cabin itself is remarkably quiet. There's generally plenty of head-, legroom and shoulder room, but backseat headroom is nevertheless tighter than in the hybrid's competitors.


The Sonata Plug-in Hybrid's trunk is smaller because of the larger battery pack, leaving just 9.9 cubic feet of cargo room compared to the Sonata Hybrid's 13.3 cubic feet. The Honda Clarity and Toyota Prius Prime also have considerably larger trunks.


Both the 7- and 8-inch touchscreens have crisp graphics and straightforward menus. But some drivers might find that it's a bit of a stretch to reach the screen comfortably. A unique gauge cluster displaying various hybrid system readouts is one of the few visible indicators that you're driving a gas-electric car.

Hyundai Sonata Plug-in Hybrid vs. the competition

Hyundai Sonata Plug-in Hybrid vs. Honda Clarity

The Sonata looks more like a traditional sedan than its primary competitors, with their futuristic and sometimes awkward style. That factor may sway you one way or the other. The Clarity Plug-in Hybrid, however, holds a clear advantage with its 48-mile electric-only range estimate, compared to the Sonata's 28-mile range. The Honda also features a much larger 15.5-cubic-foot trunk, giving it better everyday usability.

Hyundai Sonata Plug-in Hybrid vs. Toyota Prius Prime

The Toyota Prius Prime comes up just a bit short when it comes to electric only range, with an EPA-estimated 25 miles, but it's a clear winner for fuel economy. The Prius is rated at 54 mpg combined, trouncing the Sonata's 39 mpg estimate. Among these primary competitors, the Prius also has the largest cargo capacity, measuring 19.8 cubic feet, which is double the Sonata's. Holding it back, quite literally, is its slow acceleration.

Hyundai Sonata Plug-in Hybrid vs. Chevrolet Volt

The Chevrolet Volt gets high marks for its 53-mile electric-only range estimate, which was a big factor in us naming it as one of Edmunds' Best Hybrid Cars. Compared to the Sonata Plug-in Hybrid, the Volt has a similarly comprehensive list of advanced safety features, but both have equally restrictive cargo capacities and rear-seat space. The Hyundai gets a slight edge, though, in regard to interior materials quality. Read Edmunds' long-term road test of the Chevrolet Volt.

Should I lease or buy a 2018 Hyundai Sonata Plug-in Hybrid?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
