Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have unveiled a prototype electric car that folds in half.

The Armadillo-T was conceived by a research team led by In-Soo Suh, associate professor of the Graduate School for Green Transportation at KAIST, to enable drivers to park in tight spots within dense urban environments.

When folded, the micro-car shrinks from 2.8 metres down to 1.65 metres. "Once folded, the small and lightweight electric vehicle takes up only one-third of a five metre parking space, the standard parking size in Korea," said Suh.

Suh and his team based the car's design on the behaviour of an armadillo, which rolls into a ball when faced with threats from predators. "Just as armadillos hide themselves inside the shell, Armadillo-T tucks its rear body away," Suh said.

Watch the Armadillo-T in action:

Using a remote control, drivers can roll up the back of the car, spin it 360 degrees into the correct position and reverse it snugly into a parking space.

The prototype car features two seats and it has a motor in each of the four wheels. The vehicle's battery and motors stay in the same place when the car folds.

It weighs 450 kilograms, has a maximum speed of 60 kilometres per hour and can travel 100 kilometres on a 10 minute charge of the battery.

Other cars we've featured recently include the BMW's first fully electric production car called the BMW i3 and a preview of MINI's new car that includes Union Jack door pockets and a disco floor.

KAIST unveils foldable micro electric car, Armadillo-T

The small and light electric car completely folds in half when parking, making it a perfect fit for public or private transportation in an urban environment.

Looking for a parking space for hours at a busy shopping mall or being stuck on roads jammed with cars releasing large amounts of carbon dioxide are all-too-familiar scenes for city dwellers.

A group of researchers at the Korea Advanced Institute of Science and Technology (KAIST) recently developed a possible solution to such problems: a foldable, compact electric vehicle that can be utilised either as a personal car or part of the public transit system to connect major transportation routes within a city.

In-Soo Suh, associate professor of the Graduate School for Green Transportation at KAIST, and his research team introduced a prototype micro electric car called Armadillo-T, whose design is based on a native animal of South America, the armadillo, a placental mammal with a leathery shell.

The research team imitated the animal's distinctive protection characteristic of rolling up into a ball when facing with threat from predators. Just as armadillos hide themselves inside the shell, Armadillo-T tucks its rear body away, shrinking its original size of 2.8 meters (110 inches) down to almost half, 1.65 meters (65 inches), when folding.

Armadillo-T is a four-wheel-drive, all-electric car with two seats and four in-wheel motors. Since the motors are installed inside the wheels, and the 13.6 kWh capacity of lithium-ion battery pack is housed on the front side, the battery and motors do not have to change their positions when the car folds. This not only optimises the energy efficiency but also provides stability and ample room to drivers and passengers.

Once folded, the small and light (weighs 450 kg) electric vehicle takes up only one-third of a 5-meter parking space, the standard parking size in Korea, allowing three of its kind to be parked. With a smartphone-interfaced remote control on the wheels, the vehicle can turn 360 degrees, enhancing drivers’ convenience to park the car, even in an odd space in a parking lot, the corner of a building, for example.

Professor In-Soo Suh said, "I expect that people living in cities will eventually shift their preferences from bulky, petro-engine cars to smaller and lighter electric cars. Armadillo-T can be one of the alternatives city drivers can opt for. Particularly, this car is ideal for urban travels, including car-sharing and transit transfer, to offer major transportation links in a city. In addition to the urban application, local near-distance travels such as tourist zones or large buildings can be another example of application."

The concept car has loads of smart features on board, too: the cameras installed inside the car eliminate the need for side mirrors and increase the driver's ability to see the car's right and left side, thereby reducing blind spots. With a smartphone, the driver can control Armadillo-T and enable remote folding control. The car has a maximum speed of 60 km/h, and with a ten-minute fast charge, it can run up to 100 km.

Professor Suh explained that the concept of Armadillo-T was originally initiated in 2011 as he focused his research interest on the sub-A segment of personal mobility vehicles (PMVs), which are smaller and lighter than the current compact cars, as a new personalised transport mode.

"In coming years, we will see more mega-size cities established and face more serious environmental problems. Throughout the world, the ageing population is rapidly growing as well. To cope with climate, energy, and limited petroleum resources, we really need to think outside the box, once again, to find more convenient and eco-friendly transportation, just as the Ford Model T did in the early 1920s.

A further level of R&D, technical standards, and regulatory reviews are required to have these types of micro vehicles or PMVs on the market through test-bed evaluations, but we believe that Armadillo-T is an icon toward the future transport system with technology innovation."

The research project has been supported by the Korean government, the Ministry of Land, Infrastructure and Transport and the Korea Agency for Infrastructure Technology Advancement, since December 2012.

    I really hope this isn’t how the future looks…

    Protecting from what? Is that part armoured or something? No. Meaningless effort and no point.

  • Xnt

    If the folding due to lack of space is the only reason for the design, then the problem here is about society. I was expecting something along the lines of: Folds once the vehicle is in motion to reduce surface area, or reduce wear on tires (since you probably don’t need the two wheels once it’s in motion), or even provide propulsion. Untapped potential in the design.

  • Tal

    Aerodynamics are the most significant factor that affects fuel consumption and yet they are often partly overlooked in current vehicle models.

    Smart vehicles necessarily mean aerodynamic vehicles. This design doesn’t look like its creators took this factor into account.

    Why fold the car? To make it smaller when parked. Right? And if two other cars park close on front and rear, using the so called free space? What to do if no one is around?

  • Sam

    They go to a lot of effort in creating a folding car. Yet does it actually folds to 90 degrees, making it even more compact with the ability to be parked tight up against walls.

    It doesn’t even look small compared to other micro cars already available without this gimmick.

  • MZK

    One thing I don’t get is if the rear part is foldable, it means that it’s empty right?

    So then isn’t simple to just move the rear wheels to the rear of the front part, and simply remove the foldable back part? I feel that it would then be a Smart car. If there are foldable seats in the foldable rear part, then why not.

    But I feel that the only point of this car is to be foldable. Isn’t it absurd?

    Correct me if I’m wrong.

  • Gary Goldstein

    I wouldn’t want to crash in this car – a crash would likely trap you inside this thing, leaving you cocooned in an armadillo tomb.

  • Rachel Cook

    It’s brilliant, I’d love to have a go in it. It would be great if more cars like this existed, instead of the beefy vehicles we have today!

  • derekbrowns

    I would feel like I should be in the latest science fictional movie. Kind of cool.

  • So you have to be OUTSIDE the car in order to park it?

    Yeah, that’ll work (¬_¬)

  • Patrick Piklapp

    It may work outside the US, but Americans seem to feel that bigger is better and Muscle Cars rock!

  • TheD

    Automotive left me always so sad…

  • Rae Claire

    The aerodynamics isn’t much of an issue in a vehicle with a top speed of UNDER 40 mph. And I wouldn’t take a chance with it over 30. It’s just for around town – stop and go driving. Silly design, but it’s a step if it gets folks thinking about something better.
