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 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.

Hyundai Nexo fuel-cell SUV verdicts: classy, zippier, still a "niche vehicle"
https://www.greencarreports.com/news/1115410_hyundai-nexo-fuel-cell-suv-verdicts-classy-zippier-still-a-niche-vehicle

The Hyundai Nexo hydrogen fuel-cell SUV that debuted last month at the Consumer Electronics Show won't be seen on California roads for many months yet. It is expected to go on sale in the U.S. in the fourth quarter of this year, but now we have a few reports from outlets that have driven the one SUV whose only tailpipe emission is water. The general consensus is that the Nexo is a more integrated, more refined, and likely far more practical vehicle in daily use than was its predecessor. . . .

While the hydrogen-powered Tucson was good enough for a vehicle not originally designed for that powertrain, we found its performance slow, especially at highway speeds. The Nexo, on the other hand, is a dedicated hydrogen fuel-cell vehicle, meaning the model is not available with any other powertrain. . . .

While the quality of the interior materials surpasses that of other Hyundais, Auto Express said, it's still not comparable to what you'd find in standard premium SUVs from the predictable list of German, British, and Japanese players. Hyundai said it expects the car's fuel-cell stack to last at least 10 years, or twice the predicted lifespan of the one used in the Tucson Fuel Cell.

That durability is combined with comparable passenger volume and cargo space to other SUVs of its size, the reviewers said, despite the large high-pressure hydrogen tanks nestled in the undercarriage. . . .

It called the hydrogen SUV "zippier to drive" than the Tucson Fuel Cell, with better acceleration and more torque from a motor with a higher output of 120 kilowatts (161 horsepower) vs the Tucson's 100 kw (134 hp). The Nexo is projected to earn an EPA range rating of more than 350 miles, Hyundai told attendees at the Seoul drive event. . . .

In the end, Auto Express concluded, "As good as the Nexo is, it’s still a niche vehicle that’s difficult to recommend" due to the limited fueling infrastructure.

That summation falls firmly in the "Well, Duh!" category. Direct links to the Auto Express and and Automotive news articles which the GCR article is based on, are here:

http://www.autoexpress.co.uk/hyundai/nexo/102690/new-hyundai-nexo-fuel-cell-suv-2018-review

http://www.autonews.com/article/20180219/OEM04/180219745/hyundai-nexo-is-a-rolling-showcase-of-self-driving-eco-car-technology

The Auto Express article includes lots of photos. I think it's decent looking from the side, quite nice from the rear, and the front, well, it's better than a Mirai, Clarity or Prius! IMO it's the only one whose looks don't qualify it as a weirdmobile. From the Automotive news article:
The Nexo’s overall fuel cell stack is also more efficient. Its power density improves by half, its overall size drops 18 percent to save space under the hood, and it is 14 percent lighter.

The Nexo is also zippier to drive, accelerating faster than the Tucson with more torque. . . .

Meanwhile, Hyundai is loading the Nexo with new self-driving and advanced safety systems.

It gets an around-view camera blind-spot monitor that sees angles on both sides of the car that can’t be reached by traditional mirrors. It beams images the blind spots to a display in the center console of the car while changing lanes -- a system Hyundai claims is world-first technology.

The lane following assist function -- a first for Hyundai -- enables the car to steer itself down the road and keep centered in the lane. It works at speeds from 0 to 90 mph.

Finally, Hyundai is deploying a remote parking assist function in the Nexo. . . .

From the Auto Express article:
. . . Impressively, given the size of the hydrogen tanks underneath the floor the NEXO, there’s little compromise to be found in terms of space. Head and legroom in the rear is perfectly good, even for six footers, and while the 471-litre boot isn’t that deep, it’s plenty big enough for most families’ needs. There’s a decent amount of cabin storage, too. . . .

0-62mph is taken care of in a decent 9.7 seconds, and it feels sprightly enough off the line for what’s likely a two-tonne SUV. However, in the same way as a typical EV performance tails off noticeably at motorway speeds. Still, there’s enough poke to satisfy the average motorist.

Our drive of the NEXO consisted mainly of motorway driving, but even on twisting slip roads the weight of the three hydrogen tanks and powertrain was noticeable, with pronounced body lean. But ease off and you’re rewarded with a supple ride thanks to soft, long-travel suspension, and strong refinement marred only by a rustle of wind noise. We’ll have to wait for final production versions to arrive in the UK for a definitive verdict, however. . . .

No prices announced. FWIW, the Forester model I currently drive managed 9.6 sec. 0-60 when tested by C&D, and I've always found that adequate for my needs so this would probably work for me, as long as the passing capability is reasonable at two-lane mountain road speeds, i.e. start speed 20-55 mph, end speed 20 mph higher. The Auto Express article also mentions that the overall efficiency of the stack is 60%, which while not in BEV territory is still well above any ICE - I think the highest efficiency I've seen claimed for a production ICE was 40% recently, but I forget whether it was Toyota or somebody else.

2019 Hyundai Nexo Quick Spin Review | A better hydrogen fuel cell crossover
In South Korea, we test Hyundai's latest hydrogen fuel cell vehicle.
https://www.autoblog.com/2018/03/20/2019-hyundai-nexo-review/

. . . Our first stint inside the vehicle took place in the back seat, where we had plenty of legroom and clean surroundings. The interior was white and grey with matte silver metallic trim. The plastics in the Nexo aren't particularly soft, but somehow Hyundai makes them look premium with fine grains and patterns — one of the tricks Hyundai uses to make its affordable cars feel like higher-end automobiles. We were comfortable back there, especially with rear seat heaters to ward of the winter chill in the Korean mountains as we drove past the Winter Olympics in PyeongChang.

When it came our turn to get behind the wheel, we felt right at home in the comfortable driver's seat. The steering wheel was attractive in its two-tone leather, and smooth to the touch. The digital instrument panel and touchscreen extending to the right of it offered high definition images, crisp colors and ultra-quick response. The overwhelming number of buttons on the center console threw us off, though. It reminded us of a control panel for some sort of spaceship.

Driving across a foreign country, we were put at ease by the robust navigation system. Not only did it show and tell us where to go, it let us know what the speed limit was, and even identified the locations of speed cameras, something the Santa Fe was kind enough to do for us as well. Distances were in the metric system, which took some getting used to, but a shrinking bar on the nav screen helped us count down the actual distance to our next turn. We learned to focus on that rather than the voice telling us to "Turn now," which was always a little too early.

The Nexo wasn't quick, but it was smooth, and the quiet, linear acceleration was satisfying. Most of our driving took place on the highway, so there wasn't of lot of acceleration or braking or cornering . . . For this sort of driving, the quiet, calm Nexo was a pleasant companion.

Nexo is equipped with a number of driver assist features which we found helpful. Adaptive cruise control helped us keep to the speed limit (those cameras are everywhere) and maintain following distance, while the lane minder kept the car stable and centered. When we did go to switch lanes, touching the signal pulled up a camera feed on from the side of the vehicle, showing our blind spot in the center of the instrument, cluster. This is similar to Honda's system, but this covers both sides, the display is better placed, and the picture is more clear and full. In the Nexo, we found it far more helpful than distracting, and we'd like to see it come to more vehicles. . . .

Here Is How Hyundai Improved Hydrogen Fuel Cell Cars – Nexo
https://insideevs.com/here-is-how-hyundai-improved-hydrogen-fuel-cell-cars-nexo/

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 . . . .

That "370" miles is estimated, not official EPA. Photos and specs in the article, along with Hyundai's PR fluff. Only thin I don't like about it is that it's considerably larger than the Tucson, which was similar in size to my 2003 Forester (but current Foresters have similar dimensions to the Nexo, as each succeeding Gen. of a vehicle almost inevitably grows). Still no prices, but I think they need to get it down to no more than $50k to allow it to go head to head with the Model3/Y LR, and preferably $45k or less. I suspect the latter's doubtful. If they can get it to $50k, the infrastructure's there and the company is subsidizing the fuel, I suspect it will outsell the Mirai and Clarity combined here. CUVs are the name of the game these days, and the Nexo improves virtually all of the issues that handicapped the Tucson relative to the other two FCEVs.
