Official Hyundai Nexo FCEV SUV

I'll change the topic title once the vehicle's officially named. [Edit: Done, 1/8/18] Via GCC:
Hyundai previews near-production-ready next-gen fuel cell SUV; new eco-vehicle development roadmap
http://www.greencarcongress.com/2017/08 ... undai.html

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.

Production Hyundai Nexo hydrogen fuel-cell SUV appears at CES
https://www.greencarreports.com/news/1114636_production-hyundai-nexo-hydrogen-fuel-cell-suv-appears-at-ces

The 2019 Hyundai Nexo is the first dedicated hydrogen vehicle that's an SUV; the various Honda and Toyota models that preceded it have all been four-door sedans.

The Nexo will go on sale in limited markets later this year, and it sits on underpinnings designed from the ground up around its hydrogen fuel-cell powertrain.

For a compact to mid-size SUV, the Nexo has relatively sedate specifications: its motor is rated at 120 kilowatts (160 horsepower) and 291 pound-feet of torque.

Hyundai quotes a 0-to-60-mph acceleration time of 9.5 seconds. The more important figure—the range provided by 5 or 6 kilograms of hydrogen in its reinforced 10,000-psi pressure tanks—is estimated at 370 miles. . . .

The nose looks like they held a nose design contest, and then decided to incorporate every single one of the entries.
2013 "Brilliant Silver" SV with Premium and no QC, a 2009 Vectrix VX-1 W/18 Leaf modules, and 3 EZIP E-bicycles.
PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

The Japanese and the Koreans do seem to be in a contest to see who can put the ugliest nose on a production car. Meanwhile, American companies are trying to see who can put the most macho nose on a truck - my grill's bigger than your grill! :lol:

Hyundai introduces next-generation fuel cell vehicle NEXO; availability beginning later this year
http://www.greencarcongress.com/2018/01/20180109-nexo.html

The article includes several snapshots of comparison charts, including dimensions (the Nexo is longer than the Tucson, at 183.9" vs. 173.6"; slightly wider at 73.2" vs. 71.7", and slightly lower at 64.2" vs. 65.2"). 0-60 time drops from 12.5 sec. to either 9.9 or 9.5, depending on which chart you read.
