Official Hyundai next-gen FCEV SUV

I'll change the topic title once the vehicle's officially named. Via GCC:
Hyundai previews near-production-ready next-gen fuel cell SUV; new eco-vehicle development roadmap

At a special preview event held in Seoul, Hyundai Motor provided an early glimpse of its next-generation hydrogen fuel cell vehicle, which is due to launch early next year. . . .

The new fuel cell model was developed on four key pillars that focus on fuel cell system efficiency; performance (maximum output); durability; and tank storage density.

    Fuel cell system efficiency: By enhancing fuel cell performance, reducing hydrogen consumption, and optimizing key components, the vehicle’s efficiency is greatly improved compared to the its predecessor, the ix35 Fuel Cell (Tucson Fuel Cell in some markets). The new SUV boasts an efficiency level of 60%, or a 9% increase from the ix35’s 55.3%. With enhanced system efficiency, the new model targets a driving range of more than 580 km (360 miles) on a single charge (based on Korean testing standards).

    Performance (maximum output): The new model’s maximum output is enhanced by 20% compared to its predecessor, with 163 PS (120 kW) of power. The fuel cell SUV also improves the car’s cold start capability, overcoming the challenges of starting fuel cell vehicles in temperatures below freezing point. The vehicle’s architecture is optimized to allow it to be started at -30 degrees Celsius (22 degrees Fahrenheit), by incorporating key components in the fuel stack developed by Hyundai Motor. In addition to boosting the new car’s capabilities, the enhanced components—such as MEA (membrane electrode assembly) and bipolar plates—also helped to reduce production costs.

    Durability: By employing highly durable catalyst technology, the new hydrogen-powered SUV ensures even greater longevity than its predecessor.

    Hydrogen storage: The next-generation hydrogen vehicle makes significant improvements in tank storage density. The tank package now features three equally-sized tanks, as opposed to two of different sizes. World-class tank gravimetric capacity was achieved through innovations to the plastic liner configuration and efficient layering pattern, which resulted in a reduction of thickness..

The mass-produced new vehicle will also feature advanced driver assistance technologies, alongside its extensive hydrogen-powered range. The details of the new ADAS features will be disclosed in January at the 2018 CES, along with the official model name. . . .


IDK what the Korean test cycle looks like, but presumably the new car will be longer ranged than the Tucson's 265 EPA, and I'm figuring on something at or over 300 miles EPA.

The 'best' is the enemy of 'good enough'. Copper shot, not Silver bullets.
