Here Is How Hyundai Improved Hydrogen Fuel Cell Cars – Nexo
Hyundai Nexo FCEV is the next generation hydrogen fuel cell car that was introduced at the 2018 CES. It’s expected to be released in select market later this year.
Hyundai highly improved its FCEV compared to the old Tucson FCEV as the new dedicated model can go up to 370 miles (595 km) compared to 265 miles (426 km).
Acceleration from 0-60 mph improved from 12.5 to 9.5 seconds. Nexo’s electric motor is rated at 120 kW and 395 Nm.
The fuel cell is able to provide around 95 kW of power, together with 40 kW from the battery, total output of 135 kW is available.
According to Dr. Woong-chul Yang, Vice Chairman, Hyundai Motor Company “Hydrogen energy is the key to building a more sustainable society“, which means that they will not leave the FCEV segment any time soon.
Fuel Cell : 95kW

For the first time ever, Hyundai’s fuel cell vehicle is built with a dedicated vehicle architecture. This architecture has many benefits including:
- Lighter weight
- Improved power-to-weight ratio
- Faster acceleration from 0 to 60 mph than the Tucson FCEV
- More cabin space
- Allows the battery to be relocated to the trunk
- Improved fuel cell system layout
NEXO vs. Tucson Fuel Cell System Architecture
- NEXO’s fuel cell stack and battery have more net power to supply a more powerful motor
- NEXO’s powertrain is lighter and has improved packaging
- Improved hydrogen storage tanks
- NEXO’s powertrain is lighter and takes up less space compared with Tucson FCEV
- More efficient
- Better module integration
- Peak acceleration is increased by 25 percent compared with Tucson FCEV
- NEXO accelerates from 0 to 60 mph 20 percent faster than Tucson FCEV
- NEXO has more torque than the Tucson FCEV
- NEXO has 30 percent more range than the Tucson FCEV
- NEXO has an estimated range of 370 miles compared with the Tucson FCEV 265 miles
Quiet and Comfortable Driving Characteristics
- NEXO maintains the quiet and comfortable driving characteristics of the Tucson FCEV
- All of the NEXO’s moving parts are inside the engine bay which isolates the noise to one area
- NEXO has the same level of durability as internal combustion engine vehicles
- NEXO’s storage system is lighter than the Tucson FCEV
- NEXO’s storage system has world-class storage density
- NEXO can be refueled within five minutes
Improvement to the hydrogen fuel cells:
“Designed to handle extreme temperature and environments, the NEXO testing has proven that the vehicle is capable of starting after being subject to overnight temperatures of -20 degrees Fahrenheit. NEXO boasts cold start capability within 30 seconds which is an industry-leading achievement and the fuel cell system warms up faster for maximum performance. The NEXO also has excellent cooling performance on steep grades with temperatures exceeding 120 degree Fahrenheit.
Improvements in the air supply system, performance at high altitudes and refueling times, along with overall efficiency and fuel economy put the NEXO in a class all its own. In addition the NEXO has improved power density and durability comparable with a gasoline-powered vehicles.”
Nexo comes also with new features:
Blind-spot View Monitor (BVM)
Hyundai’s Blind-spot View Monitor is an industry-first technology. It shows drivers on a center cluster screen the rear and side views of NEXO using cameras while changing lanes in either direction. The system uses wide angle surround view monitors (SVM) on each side of the vehicle to monitor areas that cannot be seen by a traditional rearview mirror. Hyundai is the first automaker to provide drivers video footage from both sides of the vehicle.
Lane Following Assist (LFA) and Highway Driving Assist (HDA)
Lane Following Assist is an all-new technology for Hyundai and it debuts in the NEXO. LFA automatically adjusts steering to help keep NEXO centered in its lane of travel. LFA can keep NEXO centered at speeds between 0 and 90 miles per hour on both highways and city streets. When paired with Hyundai’s Highway Driving Assist (HDA) which utilizes sensors and map data to ensure safe operation as well as automatically adjust speed in limited environments, drivers will be able to traverse long distances with greater ease and improved safety.
Remote Smart Parking Assist (RSPA)
RSPA enables NEXO to autonomously park or retrieve itself from a parking space with or without a driver in the car. The RSPA system can even back a NEXO into a parking spot by itself with a touch of a button from the driver. When faced with any challenging parking scenario, NEXO drivers will be able to park with complete confidence and accuracy.
