Hyundai Motor has unveiled the all-new NEXO at the 2025 Seoul Mobility Show, placing its hydrogen-powered fuel cell electric vehicle (FCEV) in the spotlight once again. This new generation of the NEXO brings significant updates in design, technology, and most notably in its fuel system and battery architecture. The company aims to make fuel cell vehicles a viable option alongside battery electric and hybrid models. And no, it is not yet viable for the Indian market.
The heart of the new NEXO is its improved fuel cell system, with Hyundai achieving a substantial increase in performance and efficiency. The fuel cell stack now delivers a gross power of 110 kW, up by 16 percent compared to the previous version. The electric motor produces up to 150 kW with a peak torque of 350 Nm. Battery output has also doubled from 40 kW to 80 kW, with energy storage capacity at 2.64 kWh. These changes allow the vehicle to accelerate from 0 to 100 km/h in just 7.8 seconds, a noticeable improvement over the earlier model’s 9.2 seconds.
One of the NEXO’s key selling points is its hydrogen fuel storage system. It now holds up to 6.69 kg of usable hydrogen, spread across three tanks with a combined volume of 162.6 litres. Hyundai estimates that the vehicle can travel over 700 km on a single five-minute refill, based on Korean regulatory test standards. The improved hydrogen storage density contributes to both the increased range and better packaging without compromising cabin space. This addresses one of the key limitations of earlier FCEVs—limited range and long refuelling times—positioning the NEXO as a more practical alternative for long-distance travel.
The vehicle incorporates Hyundai’s latest technologies in its drivetrain and power electronics. The inverter system has been redesigned for higher efficiency, and the overall durability of the fuel cell system has been enhanced, especially in extreme weather. A new anti-freezing system helps the stack operate reliably in low temperatures. Additional aerodynamic enhancements such as underbody optimisations and airflow control contribute to reduced drag, helping improve overall energy efficiency.
Apart from the fuel and battery system, the new NEXO brings a redesigned exterior under Hyundai’s ‘Art of Steel’ philosophy, with sharp lines and a robust profile. Inside, it features more spacious seating, increased cargo capacity up to 993 litres, and upgraded digital interfaces including a 12.3-inch infotainment display, an AI-powered voice assistant, and a connected navigation cockpit. Advanced safety systems, including nine airbags and a comprehensive ADAS suite, also come as standard in most trims.
