Problem finding a parking space? Problem solved with a stackable car. Created primarily for metropolitan areas, the stackable car of the future has a small footprint and runs on electricity. Ok, its not cool for a long trip, but what about a trip across town?
“”We have to think of city cars as not just small-footprint vehicles that can squeeze into tight spaces but ones that can work in unison and also be almost like a parasite that leeches on to mass-transit systems,” says Mr Chin. While Smart changed the way people think about parking and size, the MIT engineers felt that, as it had not been widely adopted and congestion and pollution problems had got no better, its success had been limited.
So the MIT team started from scratch to come up with their own concept: a stackable, shareable, electric, two-passenger car. “Imagine a shopping cart – a vehicle that can stack – you can take the first vehicle out of a stack and off you go,” says Mr Chin. “These stacks would be placed throughout the city. A good place would be outside a subway station or a bus line or an airport, places where there’s a convergence of transportation lines and people.””
“The MIT concept car is a complete re-think of vehicle technology. For a start, there is no engine, at least in the traditional sense. The power comes from devices called wheel robots. “These are self-contained wheel units that have electric motors inside,” says Mr Chin. “The interesting thing is that the wheel can turn a full 360 degrees so you can have omni-directional wheel movements. You can rotate the car while you’re moving, any direction can be front or back and you can do things like crabbing or translate sideways. It’s almost like you imagine yourself driving a computer chair.”
The wheel robots, complete with their own suspension, remove the need for a drive shaft and even the engine block, freeing up designers to make new use of the space in the car.

Add wafer-thin, programmable displays that cover the interior and exterior of the car like a layer of paint, and you have a vehicle that can be customised at will. “You can imagine signalling being not just a static signal light but something more dynamic,” says Mr Chin, who suggests the words “reversing” or “turning left” could roll across the car’s body to declare the driver’s intentions. “From a heating and cooling point of view, you might want your car to be darker or lighter depending on weather. On the interior, you can customise”
