The new Sonata Hybrid and Plug-in Hybrid feature a comprehensive exterior and interior redesign, safety, suspension.
The 2018 Hybrid and Plug-in will be produced in Asan, Korea, with Hybrid availability in the first quarter of 2018 and Plug-in availability in the second quarter of 2018.
“Our new 2018 Sonata Hybrid and Plug-in models add appeal in every area, from exterior to interior design, handling, steering, ride comfort, safety and infotainment,” said Mike O’Brien, vice president of Product, Corporate and Digital Planning at Hyundai Motor America. “When combined with Hyundai’s outstanding value and efficiency, the new Sonata Hybrid and Plug-in are sure to attract even more eco-focused buyers.”
The new Sonata exterior design conveys a new appearance from every vantage point, including new wheel designs. On the inside, a new instrument panel centre stack, steering wheel, available audio/video navigation system, wireless phone charging and rear USB charge port further enhance the interior experience.
The heart of the 2018 Sonata Hybrid is a 2.0-litre Nu GDI four-cylinder engine coupled with a six-speed automatic transmission that houses a powerful 38 kW electric motor and clutch where the torque converter would normally be found. Sonata Hybrid’s Transmission-Mounted Electrical Device (TMED) delivers the same responsive, engaging driving characteristics Sonata owners expect while improving fuel economy through the use of a larger electric motor.
This innovative transmission uses an electric oil pump, which helps improve efficiency. It is possible for Sonata Hybrid to operate solely on electric power at speeds up to 120km/h by decoupling the gasoline engine from the rest of the drivetrain.
Sonata Hybrid’s Nu engine produces 115kW and 190Nm. of torque. The electric motor produces 38 kW (51 horsepower) and 205Nm of torque. Hybrid system net power is 143kW at 6,000 rpm. Sonata Hybrid SE has preliminary internal estimates of 39 mpg in the city, 45 mpg on the highway and 42 mpg combined. The Sonata Hybrid’s total range is estimated at more than 1050kilometre under typical driving conditions.
The lithium-ion polymer battery pack capacity is 1.76 kWh and the battery pack fits under the trunk floor, which allows for a flat trunk floor as well as available 60/40 split-folding rear seats. Sonata Hybrid offers 13.3 cu. ft. of cargo volume, thanks to the compact battery pack dimensions and efficient design. Locating the battery pack beneath the trunk floor helps improve cargo volume and total interior volume with 106.1 cu. ft., the most in its segment.
PLUG-IN HYBRID POWERTRAIN
Although the Sonata Plug-in Hybrid is very technologically advanced, it drives similarly to the regular Sonata Hybrid, but with the additional benefit of extended all-electric range. A 9.8 kWh lithium-ion polymer battery pack, more than five times larger than the Sonata Hybrid’s battery, gives the Sonata Plug-in Hybrid an EPA-estimated all-electric range of up to 43 kilometre, and it can recharge in less than three hours with a level-two charger.
The Sonata Plug-in Hybrid uses a six-speed automatic transmission with Hyundai’s Transmission-Mounted Electrical Device (TMED), a 50 kW electric motor, in place of a torque converter. The 50 kW electric motor is 32 percent more powerful than the motor used in Sonata Hybrid and allows EV operation at higher engine load and speed. A 2.0-litre Nu four-cylinder GDI engine coupled with the electric motor allows the Sonata Plug-in Hybrid to operate just like the Sonata Hybrid once the onboard battery charge is depleted. The Sonata Plug-in Nu engine produces 115kWand 190Nm of torque and the total system output is 165kW at 6,000 rpm.
2018 Sonata Hybrid and Plug-in come standard with seven airbags, Electronic Stability Control, Vehicle Stability Management, Traction Control, ABS and a Tire Pressure Monitoring System with individual tire pressure display and a rearview camera are also standard. LED headlamps are optional and LED taillights and DRLs are standard.
Hyundai engineers implemented many active safety technologies for the Sonata Hybrid and Plug-in to assist drivers and help prevent accidents. No longer reserved for luxury cars.
Sonata Hybrid and Plug-in offer an eight-inch colour touchscreen navigation system with Apple CarPlay® and Android Auto® smartphone integration, iPod®/USB and auxiliary inputs, SiriusXM® satellite radio and Bluetooth® phone connectivity with phonebook transfer and voice-recognition. Available upgrades include a nine-speaker Infinity premium audio system with subwoofer and external Infinity® amplifier.
