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.

Hyundai's green vehicle line might be called AE

When we got spy shots back in June of Hyundai's challenger for the Toyota Prius, intel suggested Hyundai would name it AE HEV, an acronym that possibly meant Advanced Experimental or Alternative Energy Hybrid Electric Vehicle. The Korea Herald reports that AE is indeed the tentative project name, and that it could be applied to an entire model line of green-only models with hybrid, plug-in hybrid, and electric variants. We're told the hybrid's launch is slated for January 2016, the first configuration being a five-door hatchback based around the company's 1.6-liter direct-injected Cappa engine. The size of the battery pack and capability of the electric motor are still unknown. It aims to outdo the Prius in at least two ways, one of them being to exceed the Prius' rating of 21 kilometers per liter of combined fuel economy. The other would concern model range instead of on-road range: if the other powertrain options follow, the AE could be the world's first model with three different green drive configurations (if Honda doesn't get there first). The Korea Herald said Kia will be rolling out a hybrid-only vehicle of its own called the DE. We're not sure what the specs and timeline are for that car, nor if it is included in the "22 green cars" that a Hyundai spokesman told the paper the automaker plans to release by 2020. Right now we're awaiting the initial response to Hyundai's full dive into green waters with the Sonata PHEV that just went on sale.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.
