Paradigm Shift Does G.M.’s P.U.M.A. Rethink Transportation?

When General Motors unveiled Project P.U.M.A. in New York on Tuesday (with partner Segway), it was showing not so much a vehicle as a vision for a new transportation system. And that’s high risk, high reward, because as much as new concepts are needed, they’re excruciatingly hard to actually put in place. Our highways are haunted with unfulfilled visions, from electric station-cars to statewide hydrogen-refueling networks.

The P.U.M.A. is a two-wheeled, two-seat gyroscopically balanced urban transit device with a top speed of 35 miles an hour and the potential to be remotely operated. Toyota has also shown a fanciful personal mobility option, called the i-Swing, a single-seater pod on wheels, with joystick controls.

So far, the P.U.M.A. concept is receiving cautiously optimistic reviews. “It’s exactly the right vision, and it’s the kind of thinking we need desperately in transportation,” said Dan Sperling, director of the Institute of Transportation Studies at the University of California-Davis and coauthor (with Deborah Gordon) of “Two Billion Cars: Driving Toward Sustainability.”

Mr. Sperling points out that the Low-Speed Vehicle (L.S.V.) category, limited in most states to 35 miles an hour, was created by the Department of Transportation in the 1990s to respond to the type of technology that G.M. is now talking about.

The L.S.V. category, which includes battery-powered neighborhood electric vehicles, has been slow to take off. But Mr. Sperling said he saw those vehicles, including the Chrysler GEM, gaining popularity around Davis for use in retirement and gated communities, military bases and office parks. “We need more diversity of vehicle types,” he said. “There’s no reason everything has to be 3,000-plus-pound cars and trucks. But for this to take off it needs one extra step to integrate the vehicles into the broader network of roads.”

 

For David J. Friedman, research director for the clean vehicles program at the Union of Concerned Scientists, the P.U.M.A. has possibilities, though what he called “the massive monitoring and managing of traffic to minimize congestion and maximize road usage” has been tried before; the general category is called Intelligent Transportation Systems. G.M. experimented with hands-free Buicks on automated highways in 1997, but the efforts were thwarted by high costs and driver confusion.

“We need to design our cities around something other than two- or three-ton vehicles,” said Mr. Friedman. “The data suggests that by 2030 half of the built environment in the U.S. will be new. What if we designed new suburban towns with integrated shopping so you could walk, bike or use a P.U.M.A. to get around, with conventional vehicles only for longer trips?”

Project P.U.M.A – GM’s tango with Segway births an awesome personal mobility platform for urban environments

P.U.M.A delivers 35 mile range, 35 MPH top speed, all on 35 cents of electricity 

GM and Segway have teamed up before the New York Auto Show on what they’re calling the PUMA project. The prototype vehicle was exclusively unveiled today on the Today Show. It’s no April Fool’s joke.  PUMA stands for Personal Urban Mobility and Accessibility and the prototype running around outside NBC’s Today Show this morning is an experimental prototype of a vehicle Larry Burns, GM’s vice president of research and development, and strategic planning, claims we’ll see a roadable version by January.

The interesting thing here isn’t necessarily the size – barely wide enough to fit two skinny urban dwellers — the electric powertrain — 35 mile range, 35 MPH top speed, all on 35 cents of electricity — or the added mobility it provides – not much more than a bicycle and significantly less than a gas-powered scooter — but it’s vehicle-to-vehicle communication. Not only does the P.U.M.A. talk to other units, but it can detect the presence of other types of vehicles, pedestrians and cyclists; using that info to avoid collisions. It can also join together with other P.U.M.A.s to form high-speed (if you can call 35 MPH high speed) cross-city trains capable of using special lanes for uninterrupted travel.

 

Jalopnik’s review of the PUMA after taking it for a spin goes like this:  

The first impression is of how small and simple the PUMA is. There’s barely room for two full-sized adults to sit side-by-side within its roll cage and inside, under the rough plexi windshield there’s only one control: the aircraft-like yoke.

Mounted on that yoke are two buttons; one to start things up and one to shut it down. Hit the one on the right and the cabin lifts up off the ground, balancing completely level. Move the yoke forward and the cabin rotates in front of the center of gravity, initiating forward motion. Push forward for more acceleration, pull backward to shift the cabin rearwards to decelerate or come to a stop. Twist the yoke left or right to steer. Do so at a standstill and one wheel will roll forward, the other backwards, spinning you in place. That’s it, it couldn’t be simpler. In fact, it works just like a Segway, albeit a giant one that goes 10 MPH faster and lets two people sit down out of the weather.

Riding along in complete silence, sliding fore and aft is a bit eerie. The seats aren’t connected to the floor plan, meaning your feet slide out from under the seat when the cabin shifts foreword and vice versa in reverse. That feeling of connection to the movement helps orient passengers to what’s going on beneath them.

The simplicity of the control system – immediately intuitive – hints at the intended use of the PUMA. You wouldn’t need to be competent behind the wheel of a car to use one, it’s more like operating a video game. Perfect for today’s youth gone wild.
