The next step in Hyundai's Sonata offensive launched today at the Chicago Auto Show. The 2020 Sonata Hybrid features a 2.0L four-cylinder paired with an electric motor to produce a combined 192 horsepower. This is paired with a six-speed automatic which comes with new shift programming to improve the speed and smoothness of gear changes. Hyundai touts the Sonata Hybrid will return 50 City/54 Highway/52 Combined, but that is for the efficiency Blue model. Other models will return 45/51/47 on the EPA cycle.
One interesting feature for the Sonata Hybrid is an optional solar panel roof that can extend the electric driving range by up to two miles (provided the panel is exposed to sunlight for six hours). The panel can also keep the various batteries around the vehicle charged.
No word on pricing, but the 2020 Sonata Hybrid goes on sale later this spring.

CHICAGO, Feb. 6, 2020 – Today at the Chicago Auto Show, Hyundai introduced its new 2020 Sonata Hybrid, boasting 686 miles of driving range and an EPA estimated 52 mpg combined fuel economy rating on the Blue trim. This is the first time the Sonata Hybrid has been shown in North America. The 2020 Sonata Hybrid is also equipped with the world’s first Active Shift Control (ASC) technology and a Solar Roof System (SRS), which increase driving range. The new Sonata Hybrid goes on sale this spring and is built in Asan, Korea.
Overview
The 2020 Sonata Hybrid’s exclusive styling has a slippery 0.24 drag coefficient, thanks to a unique cross-hole grille with active air flaps, a rear spoiler and aerodynamic alloy wheels. Hyundai Motor’s Solar Roof System makes its debut on the Sonata Hybrid. This system recharges the hybrid battery while preventing unnecessary battery discharge when the car is off. SRS can increase the driving range by a couple of miles after 6 hours of charging. Engineers also applied Active Shift Control technology to control the electric motor, aligning it with the rotational speeds of the engine and transmission, reducing gear-shifting times by 30%. This synchronization not only improves the Sonata Hybrid’s acceleration and fuel economy but also improves the durability of the transmission by minimizing friction during shifts.
The Sonata Hybrid is equipped with a Smartstream G2.0 GDi HEV engine and a 6-speed hybrid automatic transmission. The engine’s power output is 150 horsepower and 139 lb.-ft. of torque. The car’s electric motor delivers power output of 39 kW (51 HP) and maximum torque of 151 lb.-ft. of torque. Combined system power output is 192 horsepower and EPA estimated fuel economy numbers are 50 city, 54 highway and 52 combined for the Blue trim.

Solar Roof System
Hyundai Sonata Hybrid’s solar-panel roof directly charges the 12-volt and hybrid batteries and outputs 205 watts of electricity. This system has several benefits:
- Mileage increases by about 2 miles per day
- Helps prevent battery discharge from infotainment or HVAC systems when the car is off
- Unique design cue
Active Shift Control Technology
ASC technology optimizes transmission efficiency by monitoring gear shifts 500 times per second and precisely adjusting the transmission rotation speed for faster shift times. ASC applies new control logic software to the Hybrid Control Unit (HCU), which aligns the electric motor with the rotational speeds of the engine and transmission to reduce gear shifts by 30%. The technology also delivers smoother gear changes and quicker shift times.
“The development of the world’s first ASC technology is a remarkable innovation that incorporates precise motor control to an automatic transmission,” said KyoungJoon Chang, Vice President and Head of Powertrain Control System Group of Hyundai Motor Group. “It will not only save fuel but also provide a more fun driving experience for our customers.”
Independently Developed Control Logic Software Applied to the Electric Motor
Conventional hybrid vehicles do not have torque converters to improve fuel economy because torque converters lose energy while transferring power to the drive wheels. Although fuel efficient, such a system also requires longer shift times to ensure smoother gear changes.
ASC technology allows the hybrid’s electric motor to also take control of gear shifts by applying new software logic to the Hybrid Control Unit (HCU) to mitigate issues with slower shift time. The HCU monitors the rotational speed of transmission with a sensor installed inside the electric motor at 500 times per second to synchronize the rotational speed with that of the gasoline engine.
The synchronization reduces shift time by 30% from 500 ms to 350 ms. This improves not only the hybrid vehicles’ acceleration performance and fuel economy but also the durability of the transmission, by minimizing friction during gear shifts.
Aerodynamics
The Sonata Hybrid slips through air with 0.24 drag coefficient. The low drag coefficient is accomplished by managing airflow over and under the body. Up front, the Sonata Hybrid has active air flaps behind the grille, which close when less engine cooling is needed. A redesigned rear spoiler further improves airflow. To reduce drag under the body Hyundai engineers added several elements:
- Bumper lip
- Front- and rear-wheel deflectors
- Undercovers in the front and back of the engine bay
- Center floor undercover
- Rear undercover
Digital Key
Continuing to promote the latest advances in technology, the new Sonata Hybrid offers an optional smartphone-based Hyundai Digital Key. Digital Key uses a dedicated mobile app, Near Field Communication (NFC), and Bluetooth Low Energy (BLE) technology to allow a new Sonata to be unlocked, started and driven without a physical key, via a smartphone. Sonata’s Digital Key also allows secure sharing of virtual keys with family and friends.
Sonata owners can tailor the different vehicle functions available to each shared virtual key, and can make the key available for only a defined amount of time. The vehicle owner can preset the duration of vehicle use or limit the use to only certain features when loaning the vehicle, and can also revoke keys remotely. For additional convenience, such as using a valet service or visiting a Hyundai dealer, Hyundai Digital Key also works with an NFC card, which will be provided with each vehicle. Each Sonata still comes with traditional keys. Hyundai Digital Key is compatible only with phones using the Android operating system.
Hyundai Digital Key utilizes NFC technology, which exhibits a high level of security. The NFC wireless data communication takes place only when the device and the reader are placed several centimeters apart.
Optimized Hybrid Battery Placement
By optimizing the placement of the high-voltage hybrid battery, Hyundai engineers were able to increase trunk capacity by 2.5 cubic feet, compared with the 2019 Sonata Hybrid. This placement also helps create best-in-class front headroom and legroom.
Convenience Technology
The 2020 Sonata Hybrid features a number of advanced comfort and convenience features including an electric parking brake, Hands-free Smart Trunk, Qi high-speed wireless smartphone charging pad with cooling fan, standard Apple CarPlay® and Android Auto®, Text-to-Speech via Bluetooth®, heated and ventilated front seats and split-folding rear seats.
The top-of-the-line audio and navigation display is a wide, high-definition, customizable, 10.25-inch touchscreen monitor with split screens and natural language, and cloud-based speech recognition powered by Blue Link, while the cluster supervision display is a full 12.3 inches. The navigation system includes a bird’s-eye view in navigation maps, and drivers get HD Radio traffic flow and incident data without ever paying for a subscription. Dual Bluetooth support is also available, so two devices can be paired at the same time—one for phone calls and one for streaming audio. The navigation system also comes with three years of Blue Link Multimedia/Map updates. Hyundai’s eight-inch display audio user interface, equipped with Android Auto and Apple CarPlay, is standard on the 2020 Sonata Hybrid. An optional Bose® audio system also delivers an exceptional experience to customers.
SmartSense Safety Technologies
Sonata features Hyundai’s latest SmartSense advanced driver assistance systems (ADAS). A series of sensors and systems, often restricted to luxury cars, combine to potentially warn the driver and may take action in the event of a safety incident. Meanwhile, other ADAS systems can help the driver perform certain tasks using the car’s 3 radar sensors, 12 ultrasonic sensors and 5 cameras. These features include:
- Forward Collision-Avoidance Assist (standard)
- Blind Spot Collision-Avoidance Assist (standard)
- Rear Cross-Traffic Collision-Avoidance Assist (standard)
- Lane Keeping Assist (standard)
- Advanced Smart Cruise Control with Stop and Go (standard)
- Highway Driving Assist (optional)
