Hyundai Nexo revealed at CES: Hydrogen SUV finally gets a name, more photos

Hyundai Nexo, that's the name of the fuel-cell electric vehicle to succeed the Tucson FCEV. Built on a dedicated platform instead of using a converted ICE architecture, as the Tucson did, the Nexo packs a lighter, more compact hydrogen powertrain and a more powerful electric motor to deliver improved performance everywhere. The Nexo also plays a key role in Hyundai's "Hydrogen Life Vision," which aims at integrating hydrogen as a home energy source. The power density of the Nexo's stack increases by 50 percent, and overall system efficiency goes up 5.1 percent. The smaller engine contains fewer moving parts, and even the hydrogen tanks are 36 pounds lighter than those in the Tucson FCEV. View 11 Photos The Tucson FCEV uses a 100-kW electric motor that provides 221-pound-feet of torque, and after the 90-second preparation and stack heating time on startup, the Tucson accelerates from zero to 60 miles per hour in 12.5 seconds. The Tucson's two storage tanks held 140 liters of hydrogen (37 gallons) that could provide about 295 miles of range and an EPA rating of 50 mpge. The Nexo uses a 120-kW motor with 291 lb-ft, is ready to go in 30 seconds after starting, and accelerates to 60 mph in 9.9 seconds. The new FCEV's three storage tanks hold 156 liters of hydrogen (42 gallons), which Hyundai says are good for more than 350 miles on the EPA test cycle. In a real-world run from Los Angeles to Las Vegas, Hyundai said the Nexo returned a 360-mile range and 57 mpge. Refilling the 700-bar system will take five minutes. The Nexo will introduce some of the carmaker's new technology, too. Lane Following Assist keeps the Nexo in the center of its lane in the city and on the highway, and recognizes road edges when lane markings aren't clear. Blind-spot View Monitor displays an image of either side of the vehicle when the driver plans to change lanes. The Nexo parks itself autonomously, and returns, with Remote Smart Parking Assistant Hyundai envisions owners of this second-generation FCEV beginning to use the Nexo as an integral part of their lives, not merely as an appliance. At the Consumer Electronics Show, Hyundai will have the Nexo hooked up and providing power to a demo household as part of the automaker's "Hydrogen Life Vision." The carmaker's also got plans for using the Nexo's "pure water to grow vegetation" (water and water vapor are the only emissions byproduct of FCEVs).

Genesis designer Luc Donckerwolke talks new sedan, 'post-SUV' phase

Luc Donckerwolke's office at the Hyundai Research and Design center outside of Seoul looks like an Apple store, all polished concrete, metal and glass and a Miesian lack of ornamentation. This makes sense in an environment in which Donckerwolke, as head of design for the Hyundai and Genesis brands, is attempting to privilege transparency: enhancing communication and accessibility. "We have to break this kind of castle syndrome that the designers are in," Donckerwolke says. "It's all about opening up." This undermining of Korea's traditional orchestrated, hierarchical and executory structure is part of what has allowed Donckerwolke to create widely admired concepts such as the GV80 SUV and Essentia electric GT in just more than two years since he arrived from the VW Group leading design at Bentley, Lamborghini and Audi. And also to design the all-new G70 sport sedan that will be introduced to the U.S. market later this summer. We drove the G70 just before arriving for an exclusive one-on-one at Donckerwolke's R&D office, the first American journalists to visit. Although our time behind the wheel was brief, and we drove only the top-of-the-line, 365-horsepower, twin-turbocharged V6 version, we were impressed with the acceleration, the balance and the material quality. We also noted that the G70 is very good looking, with a distinctive, muscular and aggressive mien that feels true to the company's mission to be at once "Audacious, Progressive and Distinctly Korean." Like much of what we saw and experienced in contemporary Seoul, the car hosts a unique blend of influences from America, Europe and Asia while offering a harmony of line and a grounded sense of self that seems endemic to the peninsula. This global-but-flavored template is intentional. "We are not going to do Korean cartoons on wheels," Donckerwolke says. "We're not going to become a patriotic Korean movement. It's only about the essence of the Korean culture that we are using as an inspiration." One thing we could not help but notice is that the G70 is a sedan, joining a pair of older, Hyundai-based sedans, the G80 and G90, to complete the Genesis lineup. This feels somewhat inauspicious in the moment, especially for the American market where two-thirds of new-vehicle purchases are trucks and SUVs. "As you probably have seen when you've been driving around, sedans are extremely demanded here in Korea. And, you know, we have a huge market penetration here.

We check out Hyundai's HRL exoskeleton, a robotic mobility suit for paraplegics

Hyundai makes some of the largest vehicles in the world – to wit, 185,000-ton ships with 56-foot high engines making power at 84 rpm – but its R&D division has found enough human-factor synergy with autonomous vehicle development that they're now working on robotic exoskeletons. We were recently introduced to two of these devices: the HRL designed to increase mobility and therefore quality of life for paraplegics; and the WEX, designed to assist in repetitive-motion lifting. Both of these machines are powered by replaceable lithium-ion battery packs with a 4-hour run time and 40-minute recharges. The HRL robotic legs are designed for people 64 to 71 inches tall and less than 250 pounds. The aluminum segments are adjustable in centimeter increments over a 10-cm range, and the 22.4-inch width means it would fit in many long-haul aircraft forward seats. With the 4.4-lb battery pack, the HRL weighs about 41 pounds. There are six 50:1 reduction-gear actuators, two pelvic actuators rated at 224 pound-feet of peak torque with 60-degree range of motion, and two hip and knee with 112 lb-ft peak, 180 degrees and twice the rotational speed of the pelvic motors. Twenty sensors control it all with default speed of just under a mile per hour and a top speed of 1.5 mph, and step length can be adjusted by smartphone via Bluetooth. One of the accompanying crutches has four thumb buttons much like a video-game controller, though they're experimenting with simpler inputs including a joystick. The crutch communicates with the leg unit over a few feet of distance via Zigbee wireless protocol, with security layers added for both obvious reasons and to ensure two users in the same vicinity won't transmit to the other's unit. An HRL can help you sit, stand, walk or climb and descend stairs; it will also stand on its own, simplifying the process of putting it on. Your correspondent is outside the design height limits so rather than do any impromptu CG research we deferred to colleague Chris Davies of Slashgear for impressions wearing it: "It grips tightly, the support would be comforting, and it delivers good posture. It does take some getting used to – when it first lifts up a leg to move it forward you do feel like you're going to fall over – but once you establish a gait and stop over-thinking it becomes much easier." Indeed, he never fell over and most who tried established a rhythm within a few minutes, if not a 1.5-mph sprint.
