Vehicles that can operate autonomously without humans at the wheel to guide them can be very useful, especially in conditions which may be hazardous to humans. For instance, they can be used to enter areas which may be highly contaminated with radiation to perform various activities or carry various types of payload while traveling over challenging terrain. They could even be used on the moon or other planets, like the various machines that have been roaming Mars for years.

Hyundai Motor Group’s New Horizons Studio, in partnership with Autodesk and Sundberg-Ferar, have developed such a vehicle which they have named TIGER (Transforming Intelligent Ground Excursion Robot). It is the company’s second Ultimate Mobility Vehicle (UMV) and the first designed to be uncrewed.

The development of the TIGER is being carried out at the studio which has its headquarters in California. The facility was established in late 2020 to develop UMVs drawing on research and innovation leadership from Silicon Valley and other innovation hubs.

“Vehicles like TIGER, and the technologies underpinning it, give us an opportunity to push our imaginations,” said Dr. John Suh, Head of New Horizons Studio. “We are constantly looking at ways to rethink vehicle design and development and re-define the future of transportation and mobility.”

Capability across remote, inaccessible terrain
The TIGER’s exceptional capabilities are designed to function as a mobile scientific exploration platform in extreme, remote locations. Based on a modular platform architecture, its features include a sophisticated leg and wheel locomotion system, 360-degree directional control, and a range of sensors for remote observation.

A large load bay housed within its body means the TIGER can carry goods for delivery, or be deployed to deliver aid packages in emergency situations. Leg-wheel articulation enables it to tackle a range of extreme situations while keeping payloads more level than a typical ground vehicle.

With its legs retracted, the TIGER moves like an all-wheel drive vehicle and is in its most efficient mode because it moves by rolling traction. But when the vehicle gets stuck or needs to travel over terrain that is difficult or impassable for wheels alone, it uses its walking ability to get unstuck or more easily travel over that terrain. This was a feature previously seen in the Elevate, the Korean group’s first-ever UMV concept with moveable legs, which was displayed at the 2019 CES (Consumer Electronic Show).

Like the Elevate, which also had transforming 4 leg-wheel ground vehicle, the TIGER shares similar characteristics such as its legs and wheels. The difference between the Elevate and the TIGER is that, while the former can carry passengers, the latter is uncrewed. Both vehicles blend robotic and wheeled locomotion technologies, allowing them to traverse terrain beyond the limitations of even the most capable off-road vehicle.

The vehicle can also connect to unmanned aerial vehicles (UAVs) which can fully charge and deliver the TIGER to inaccessible locations.

The first TIGER
The first version is the X-1 (‘X’ for ‘experimental’) and brings together a wide-range of technological and design expertise. It fuses Autodesk’s generative design capabilities with Hyundai’s growing R&D capabilities in mobility. The teams have been working together to create a lightweight but incredibly strong structure, with the legs and certain chassis elements created using carbonfibre composite additive printing.

The New Horizons Studio has been focused on developing technologies to enable concept vehicles such as the TIGER. These technologies include wheel-leg locomotion, high-performance materials and structures, high-performance power systems, chassis and body systems, virtual development and evaluation systems, and human-centered design and systems. Each of these represents significant technical progress that can be applied to any vehicle and will speed the development of advanced mobility solutions.

UMV concepts in development do not rely solely on wheels and are expected to address challenging driving situations – for example, a car with robotic legs could save lives as the first responder in natural disasters; or people without access to a curb ramp could hail a car to walk up to their front door, level itself and allow wheelchairs to roll in.

The Hummer returns… as an EV supertruck with 1,000 horsepower (w/VIDEO)

Hummer – that’s a name which immediately brings to mind a huge vehicle that served the military (mainly the American one) as well as the civilian version which had a niche of its own. ‘Hummer’ was actually the civilian name used by General Motors but the model was discontinued after 2009 when its sales diminished so much that the business was no longer viable.

Although GM tried to sell off the business, it did not succeed and just kept it in the ‘drawer’. Now, that name has been revived with a completely new model from its GMC subsidiary. However, unlike the original fuel-guzzling monster, the new Hummer not only doesn’t require conventional fuel at all but it is also a zero emissions vehicle.

Electric supertruck
GMC engineers have developed it as an electric supertruck with the company’s Ultium Drive and batteries. An estimated best-in-class 1,000 horsepower and estimated 15,592 Nm of torque are generated by three separate motors within two Ultium drive units that provide 4WD capability. 0 to 60 mph (96 km/h) acceleration is claimed to be around 3 seconds which is pretty quick for a pick-up though that can be expected of a super EV truck.

800V DC fast-charging compatibility of up to 350 kilowatts enables nearly 160 kms of range to be available after recharging for 10 minutes. A full battery back is said to be good for up to 550 kms.

Superior off-road capabilities
Aiming to out-do other electric trucks that are also appearing lately, the Hummer has 4-Wheel Steering, Adaptive Air Suspension with 149 mm of variation, and underbody armour. The 4-Wheel Steering system has CrabWalk which allows the rear wheels and front wheels to steer at the same angle at low speeds. This enables diagonal movement of the vehicle for greater manoeuvrability on difficult terrain.

As standard, the Hummer comes with 35-inch MT tyres and customers can specify up to 37 inches. The tyres complement the vehicle’s off-road capability which includes climbing vertical obstacles 455 mm high and driving through water more than 600 mm deep.

For crossing difficult and unknown terrain, the Hummer has UltraVision, a system of front and rear underbody cameras with live ‘virtual spotter’ views to help drivers spot obstacles and place wheels on and off the trail. There are up to 18 camera views available from the vehicle.

Prepared for autonomous motoring, the Hummer will have optional Super Cruise, a driver assistance feature that can support hands-free driving on more than 322,000 kms of enabled roads. There will also be a new automatic lane-changing feature where the system can determine when a lane change is optimal and initiate the manoeuvre, while following signalling protocols.

Minimal original design elements
GMC’s designers drawn minimally on the original model’s monolithic appearance, instead aiming for something that looks futuristic and bold with a pick-up profile. “Its design visually communicates extreme capability, which is reinforced with rugged architectural details,” said Phil Zak, Design Executive Director.

Emphasis on technology
The interior is also given premium appointments and as expected, technology is emphasised. For example, off-road widgets display vehicle functions and terrain status through the infotainment and driver information screens. The driver can be informed of torque output, differential locker engagement, tyre pressures, pitch and roll angles, friction circle, torque vectoring and more.

Open-air driving is an option, made possible by the Infinity Roof and removable transparent Sky Panels that can be stowed in the storage compartment at the front of the vehicle. The MultiPro Tailgate opens with 6 functional positions, while the glass panel at the rear of the cabin and the tonneau cover can be opened at the touch of a switch as both are powered.

4 versions, starting from late 2021
There will be at least 4 versions of the Hummer with the first one known as Edition 1 going on sale in the fourth quarter of 2021. This will be the most expensive version at US$112,595 (about RM467,000) and will be the only one available for at least 12 months. Another version will be launched in late 2022 which is currently projected to cost less than US$100,000 (RM414,000).

In early 2023, the third version will be available, and then a fourth version will be in showrooms a year later, in 2024. The fourth version will have two motors and be priced at under US$80,000 (RM332,000).

Hyundai turns the Veloster into a go-everywhere vehicle with the Grappler Concept

Hyundai Motor’s latest Veloster Grappler concept for the 2019 SEMA show in Las Vegas is another of those ideas which take accessorizing to extremes. While it’s not intended to resist zombies like the Santa Fe Zombie Survival Machine of 2013, it nevertheless would be worth having when things get really bad on the planet.

The Grappler concept takes a Veloster and raises the ground clearance, immediately giving it off-road capability especially with sharper approach and departure angles. To protect the underside against rocks and other hard stuff, there are custom front and rear brush guards.

Oversized all-terrain tyres and rally-themed Method Racing wheels yield a menacing demeanour and functional capability, while Borla cat-back exhaust components add a visceral audible resonance. A custom vinyl exterior body wrap features a ghosted Hyundai-themed livery. Finally, a Seibon carbon-fibre bonnet effectively vents excess engine bay heat when things heat up out on the road.

*Goal Zero portable power station with solar recharging*

For extra cargo capabilities, a roof-mounted Thule utility basket includes a high-output lighting system from Baja Designs. The utility basket serves as a base mount for the removable solar panel from Goal Zero, powering an all-electric portable power station mounted inside the cabin for remote journeys.

A full host of roof-mounted utility lights – from high-speed desert off-roading high beams to basecamp work lights – provide the right illumination at any time.

Inside the cabin (Hyundai has not released pictures yet), the functional ruggedness theme continues. An integrated roll bar provides occupant protection and facilitates mounting for a full-size spare wheel and tyre. Further outfitting the interior are traction mats, an oversized utility shovel, a Goal Zero portable power station, roadside assistance kit, first aid kit, Napier outdoor dome tent, Scosche Mounts, Goal Zero crush lights and premium Recaro seats finished in a vintage houndstooth check pattern.
