2019 Hyundai Sonata Plug-in Hybrid Fuel Economy

The 39 MPG combined rating of the 2019 Hyundai Sonata Plug-in Hybrid signals that it’s designed for economical commuting. It’s transportation for the pragmatic driver who wants to minimize their carbon footprint and trips to the gas station, without sacrificing space and comfort. It isn’t a sports sedan, designed for towing, or aimed at off-road adventures.

City and highway performance

The Sonata Plug-in Hybrid performs well in environments with stop-and-go traffic. Its 37 MPG city rating shows its ability to use its electric motor for low-speed movement, minimizing gasoline use during slow driving. On the open road, the 42 MPG highway figure is still good, proving that the Sonata Plug-in Hybrid remains efficient even when relying more on its 2.0L 4-cylinder engine at higher speeds. This mix of city and highway ability is important for commuters who face mixed driving conditions daily.

Annual fuel cost

According to EPA estimates, the 2019 Hyundai Sonata Plug-in Hybrid will cost owners approximately $1,100 per year in fuel. This number is based on driving 15,000 miles annually, using national average fuel prices. This is important for prospective buyers. While electricity costs are not factored into this specific number, the Sonata Plug-in Hybrid’s ability to run on electric power for shorter trips makes the $1,100 figure potentially even lower for owners who charge their vehicle often.

Real-world expectations

The EPA provides standardized testing, but it’s important to manage expectations when it comes to real-world fuel economy. Factors such as driving style, terrain, climate, and charging frequency can all influence how far the Sonata Plug-in Hybrid can go on a gallon of gasoline. Quick acceleration, frequent use of air conditioning, and hilly routes will decrease fuel efficiency. However, drivers who prioritize smooth acceleration, use regenerative braking, and consistently plug in the vehicle can often meet or even exceed the EPA estimates. This vehicle rewards a mindful approach to driving.

How it compares

In the mid-size sedan segment, the 2019 Sonata Plug-in Hybrid faces competition primarily from other hybrid and plug-in hybrid models. The Toyota Camry Hybrid LE, for example, boasts 52 MPG combined, making it a more fuel-efficient option. However, the Sonata Plug-in Hybrid offers the added benefit of all-electric driving range, a feature the Camry Hybrid lacks. The Honda Accord Hybrid achieves 47 MPG combined.

The competitive edge comes from a comparison to other plug-in models. The now-discontinued Ford Fusion Energi was rated at 42 MPG combined, but older models may be outdated in terms of technology and driving experience. The Chrysler Pacifica Hybrid, while a minivan, offers similar plug-in capabilities with a combined rating of 32 MPG, but suits a different buyer who wants passenger and cargo space. These comparisons highlight the trade-offs buyers make when choosing a plug-in hybrid.

Tips to maximize efficiency

Use the electric mode. The Sonata Plug-in Hybrid’s ability to travel a certain distance on electricity alone is its greatest advantage. Prioritize charging the vehicle whenever possible, especially before shorter trips, to maximize electric-only driving and minimize gasoline use. Consistent charging unlocks the car’s full fuel-saving potential.

Anticipate traffic flow and practice smooth acceleration. Avoid abrupt starts and stops, as these actions drain the battery and fuel tank. Gradual acceleration and anticipating traffic patterns will help maintain a steady speed and optimize the efficiency of the electric motor and the gasoline engine. Using cruise control on the highway can also lead to more consistent fuel economy.

Use the regenerative braking feature. This system captures energy during deceleration and braking, returning it to the battery pack. By gently easing off the accelerator and allowing the regenerative braking to slow the vehicle, you can help replenish the battery and extend the electric driving range. Mastering this technique can improve overall fuel economy.

Check tire pressure regularly. Underinflated tires increase rolling resistance, which can negatively impact fuel efficiency. Ensure that your tires are inflated to the recommended pressure, which can be found on a sticker inside the driver’s side doorjamb. Proper tire inflation improves fuel economy, enhances safety, and extends tire life.
