Hybrid Mileage in a Midsize Sedan
Auto manufacturers can call a car “all-new” if it has gone through a complete redesign, top to bottom, inside and out. Then there is something called a mid-cycle refresh, where only certain items are changed, buying the manufacturer a bit of time before the all-new model comes out. With the 2018 Hyundai Sonata Hybrid, the Korean company landed somewhere in-between the two with the changes and upgrades far more significant than the usual refresh. The biggest take-away Hyundai wants you to know is they have increased the value on the 2018 Sonata Hybrid. Yeah, we can all get behind that.
Drivetrain and Performance
The 2018 Sonata Hybrid is powered by a 2.0L four-cylinder engine, producing 154 horsepower (hp) and 140 pounds-feet of torque. The 38 kilowatt electric motor is good for 51 hp, bringing the total system horsepower to 193. Power gets to the front wheels through a six-speed electronic automatic transmission with Shiftronic, if you want to go through the gears manually.
EPA fuel economy estimates are 39 mpg city/44 highway/41 combined, heady numbers that Clean Fleet Report knew we could surpass. In 302 miles of freeway and city driving, we averaged 42 mpg, but on a 100-mile open freeway run, with the smart cruise control set to 65 mph, we averaged 44.6 mpg. So far so good, but the big test comes from the fuel economy in heavy stop-and-go traffic, where the hybrid system can run on pure electricity at times. Our last test run, over 120 miles of Los Angeles traffic during rush hour on the 405, we averaged 49.6 mpg. At times, the meter read 50+ mpg, but the final reading was just a tick under that very magic number. No complaints, though, as getting into the high-forties for every mile driven is wonderful.
Fuel economy reported by Clean Fleet Report is non-scientific and represents the reviewer’s driving experience. If you live in cold weather, high in the mountains or spend time in the city or stuck in rush hour traffic, then your numbers may differ.
The Sonata hybrid traveled 0–60 in about eight seconds. The time did not vary much leaving the car in automatic or opting for Shiftronic, where you can manually select gears by pushing forward to upshift and backward to downshift. The automatic had smooth, quiet shifts and seemed to find the right gear at the right time to squeeze-out maximum engine performance. During lane passes at highway speeds and climbing hills, the six-speed automatic shifted up-and-down seamlessly and precisely, but the engine lacked that extra oomph that would be expected from a hybrid.
Driving Experience: On the Road
Weighing in at 3,560 pounds, the 2018 Hyundai Sonata Hybrid performed well in all driving situations. Steering was responsive, but a bit heavy, with the motor-driven power steering set for good road feel. Usually, the cars Clean Fleet Report tests have the power steering set too light, so experiencing the Sonata Hybrid’s heavier setting was unique—but good. The rack and pinion steering with MacPherson struts up front and a multi-link set-up in the rear produced a soft suspension, making freeway cruising a very nice experience. The car never was floaty at freeway speeds, nor was it affected by the grooves cut into SoCal’s concrete freeways for water diversion.
The Kumho Solus 215/55R17 tires, on the 17-inch Eco-spoke aluminum alloy wheels gripped as well as an all-season tire can do. They roll smooth and quiet, so while the Sonata Hybrid is not to be considered sporty, it was never a handful. Handling was aided by Hyundai’s vehicle stability management system which included traction control, resulting in little body roll until pushed past its limits when cornering. It took a bit of trial and error to get the feel with the brakes, though.
Common on all hybrids is a regenerative braking system that converts braking or coasting into electricity, which charges the Sonata’s lithium-ion polymer battery. You can monitor the battery charge and mileage range (metered instantly with dash gauges) when driving around town, stuck in stop-and-go rush hour traffic or coasting down hills.
It is not unusual for regenerative brakes on hybrid or electric cars to be mushy or grabby. The 2018 Hyundai Sonata Hybrid brakes were a bit of both. Most noticeable on the grabby side was first thing in the morning when leaving the driveway. The mushy sensation came when tromping on the pedal at freeway speeds. However, stopping was consistent and confident, from the four-wheel disc, ABS system with brake assist.
Driving Experience: Exterior
Hyundai says the redesigned Sonata Hybrid “is a perfect blend of style and efficiency” and that its “fuel efficiency flows from leading-edge design.” Clean Fleet Report’s test car was painted in Metropolis Gray and had Hyundai’s signature cascading grille. Added in 2018, along with a new front fascia, hoods and fenders, the Sonata has a contemporary look. The LED projector headlights, with Dynamic Bending Light, wrap far back onto the fenders. Except for the panoramic sunroof and the shark fin antenna set just above the rear solar control glass window, the line from the front fascia to the rear, built-in deck spoiler is unobstructed. The rear end, with LED tail lights, has three, tasteful chrome elements of the Hyundai logo, all-caps “SONATA” and a small, lowercase “hybrid.” The rear badge and the front fender-mounted “Blue Drive” emblems are the indicators that you are driving an electrified car.
Driving Experience: Interior
Soon after sitting down, it is apparent the Sonata’s interior will be a pleasant place to spend your time, as the leather seating surfaces have a high-quality feel. The driver seat was eight-way adjustable, with lumbar and height adjustments and memory, while the front passenger gets a six-way power adjustable seat. Both front seats are ventilated and heated; padding and thigh bolstering was ample so as not to induce fatigue on long drives. The center armrest is positioned nicely and the 12V, USB and Aux ports are conveniently located at the base of the center stack.
The Sonata Hybrid seats five passengers, as in three out back. Two is best as on long trips, the center passenger might think they drew the short straw. Rear seat head, shoulder and leg room was ample for six-foot passengers and access/egress was excellent. Passenger comfort was in mind with rear HVAC ducts, USB port, door cup holders and retractable side window shades. The flat-folding 60/40 split rear seat also had a fold down armrest with cup holders. Storage with the seats folded flat was the key to getting the most utility out of the Sonata.
The high-mounted touchscreen sits just above the center stack and is placed in the dash, not jutting-out from the dash. We were pleased to see volume and channel knobs for the radio, and one each for the fan speed and temperature control. Simple and easy to understand. Soft and hard touch materials were combined well, with the subtle use of brushed chrome accents and wood grain trim, gave the dash, door panels and center console a feeling of quality. The large, round speed and tach gauges, with black backgrounds and white numbers, are extremely easy to read. As noted earlier, the hybrid gauges are easy to understand, as is the color LCD trip meter to check on that excellent fuel economy.
The eight-speaker Infinity Premium Audio system, with subwoofer and amplifier, was part of the infotainment (information and entertainment) package. The 8.0-inch high-resolution color touchscreen houses the navigation and the AM/FM/CD/MP3/AUX radio. Features include SiriusXM (90-day trial), Apple CarPlay and Android Auto. The heated and leather-wrapped steering wheel has mounted controls for Bluetooth that offers hands-free telephone, voice and radio controls.
Our 2018 Hyundai Sonata Hybrid Limited came equipped with a power tilt and sliding sunroof, exterior mirror memory, power windows and door locks, proximity key entry with push button stop/start, electronic parking brake and the very helpful automatic vehicle hold, an auto-dimming Homelink rear view mirror, power and heated side mirrors with turn signals, dual automatic climate control with rear vents, carpeted floor mats, and a tilt and telescopic steering column. The wireless charging for compatible smartphones was a nice touch.
