MIT City Car conceptual drawing  (Source: SciFi.com)
MIT dreams up a rentable, stackable, all-electric car for cities

America just seems to be obsessed with large vehicles. Maybe it’s our expanding waistlines, image consciousness or our "You can't tell me what to do, so I'm gonna buy whatever I want" mentality that persuades people to transport junior in a Suburban, go grocery shopping with a Tundra CrewMax or take Fido to the get his yearly shot in an Escalade EXT.

With rising gas prices, an increasing attention to our consumption of fossil fuels, an increasing awareness of vehicle emissions and expanding city centers, many are looking for more cost effective and efficient ways of transporting people in metropolitan areas. MIT Media Lab's Smart Cities group is thinking small with a new stackable car to reduce emissions and congestion in and around city centers.

The MIT "City Car" would be an all-electric vehicle capable of carrying two passengers and their cargo. The vehicles would be located near train stations, bus terminals and airports to ferry travelers to their final destination.

"The problem with mass transit is it kind of takes you to where you want to go and at the approximate time you want to get there, but not exactly," said Ph.D. candidate Franco Vairani of MIT's school of architecture. "Sometimes you have to walk up to a mile from the last train or subway stop."

The City Car will be stackable -- the entire back end of the vehicle would rise up allowing as many as eight of the vehicles to fit into a conventional parking space. The vehicle itself would also be mechanically simple with the electric motor, steering system and suspension enclosed within the wheel hubs.

The vehicle is said to weigh between 1,000 to 1,200 pounds and will be powered by lithium-ion batteries. According to Vairani, there could also be multiple versions of the City Car to accommodate a certain city's needs. A City Car destined for use in New York City might have a less powerful battery and a lower top speed due to traffic congestion. In other cities where interstate travel is more frequent, more powerful batteries capable of propelling the City Car faster and farther could be used.

If all goes well, MIT will show a prototype of the City Car sometime next year.

Sounds like a great idea. Small, cheap rental car that gets the job done without a lot of flair.

Add a DARPA Urban challenge system to this thing so that you can rent for one way trips (and have the car bring itself back home) and you have the perfect setup for city cars.

It might not fit well in rural areas, but if they will sell them to regular folks in non-metro areas, I bet they will sell a few here and there.

I like the idea too. People have this idea for London where they would only have these kind of cars and they would be remote controlled. Sorta like automatic taxis. I really think cars as we know them today will be extinct by the next century or so.

In any event, these look cool, though I'm not sure how well they'd do up here in Canada during the winter ;)

The idea is interesting, but I am trying to see how useful these would be in NYC.

I currently live in NYC, and I don't see how they could possibly compete with Taxi's unless they are literally flooding the city with them. I can go anywhere in the city for a max of $25 with a tip, have 4 people in the cab, load the back with a ton of luggage/purchases, and not need to drive. The City Car doesn't seem like it would have the cargo space to fit anything too large with you.

It is a great idea, but unless the pricing is very very low, the market won't be large at all, least not in NYC.

If you made the entire Manhattan section free from regular cars and then only allowed these (and service vehicles)... now that would be cool.
More room for walking and tiny cars, and all you'd need is a parking lot and tiny car rental station outside of Manhattan. Of course the taxi companies would never go for this (unless they could have tiny taxis)

Why would you need these if you unbanned taxis? What, you've got something against taxi drivers or something?

perhaps larger versions more the size of say a mini-van will be produced and taxi drivers can transport with those instead... will cost less because gas isn't being used and will be better for the environment. They could just charge them over-night (or during the day for night shifters). I personally think cutting taxis out is a bad idea because then all those jobs are lost... there are a hell of a lot of taxi drivers. And, at least for now, I'd rather have a person driving me around than a computer.

But props to MIT for working towards a solution to one of problems of living in a large city... and energy.

Not only that, but if the taxi drivers are anything in NYC like they are in any other urban area where I've been, it's highly likely that this itty-bitty little electric car is going to be playing bumper tag with 5000+ pound taxis...... and losing!

Yellow cab, FTW!!

How is $25 a good deal? You can easily spend $50 going back and forth from your apartment in a given workday. That's $250 a week. Obviously, people usually use the metro, which is affordable, so total dependence on taxis is not realistic. The point is, Taxi's are a terrible deal vs. a rent by hour car program as proposed by MIT. I use Flexcar for $5.50 an hour here in Gainesville. It's cheap, has great availability, and gas and insurance is included. I know in most metropolitan cities Flexcar is around $10 an hour. Also, there are about 8 vehicles around campus to choose from. Trucks for when I haul things, SUV's for day trips, and Hybrids for groceries.

Well no one in NYC is going to commute at $25 each way, roundtrip, I just proposed every day by taxi (That would be from E96 St. down to Battery Park City (bottom of the island on the west side), one of the longer drives; and people who can afford that fare for commuting are doing it by black car, or just taking the Subway for like $3/day.

I tried to look up Flexcar for NYC, but didn't find anything, so went with ZipCar pricing. Cars in my area are $10-14/hr; so you are looking at $20-28 round trip if you can somehow just go one way each trip and not get charged for anything else. Your average taxi cab is likely $12-15 a trip (like 50-60 blocks), so $24-30 round trip.

So for a few extra dollars, you do not have to drive, park, etc. Do ZipCar / FlexCar allow you to drop the car in a different place? Otherwise, you are then paying Parking (the first hour in NYC will be $20+, a couple hours tends to be $30+) unless you happen to have the luck of God and find street parking.


Wonder how it would...

I wonder how it would handle in colder climates and deal with snow, slush, rain, wind, etc... At 1200 lbs it might blow over pretty easily in decent wind.

They also fail to consider more modern metro areas like Phoenix. Most traditional urban areas have well developed mass transit system, but larger metro areas have little to none.

That thing would be nothing more then a pancake on an Interstate.

It's not intended for the interstate, hence the name, "CITY CAR"

Cities like Phoenix make large use of Interstates, which is what I was referring to as modern cities.

I wish other cities weren't so opposed to building more highways. It seems in the DC area freeway is a scary word, but when I lived in Phoenix I could go 4 times the distance in the same amount of time and that was all due to a robust freeway and Interstate system.

How do you get your car out if its in the middle of the stack i wonder?

It's a rental. Take the one at the front of the line.

And what about all your shopping purchases you left in the trunk?

Oh wait...another thing you can't do with these more "practical" cars...

True, but you'd have just as much trouble on a bus or train if you bought a lot of stuff at the store. These cars aren't being pitched as a replacement to personal vehicles, but more as a decentralization of mass transit that will allow passengers more freedom than what is currently available in many urban areas.


It's a solution looking for a problem...

As AmbroseAthan notes, Taxis have the "big city" market covered, along with public transit.

The problem in the US is not people living in New York City or San Francisco driving from one point in their city to the other, it's the people who live outside of the city who need to get in and can't/won't use public transit. This solution won't help them.

It also won't help the people who live in smaller cities and towns where mass transit doesn't make sense. In these markets you are literally stuck without a car - and one that you can drive alot farther than a li-ion battery will take you.

It's cute - but it's just like the Segueway: Techno-cool but real-world useless.

America is a country that presents a unique set of challenges to anyone interested in improving our transportation system. Carpool? People in my neighborhood work all over a 100 mile radius. Mass transit? The density of my small town doesn't support it. Move closer to where you work? My wife commutes 50 miles north - while I travel 5 miles south. If we move to the geographic middle, we would still spend the same on gas.

There are a number of constraints to any solution. Few businesses give preference to candidates who live close by. Most households have two wage earners, so moving doesn't help much. The big cities work for some people - but not all.

Plus America is huge. You can fit the entire country of Japan into California. The only place that we have the pop density of Western Europe is in the Northeast - an array filled with mass transit systems and the only place where Amtrak is profitable.

But people are already responding to $3/gallon gas. Hybrids are popular whereas the Hummer and heavy SUVs are not. People will follow their pocketbook and buy more efficient cars.

But cutesy solutions like this? Nope.

These cars are small, relatively cheap to produce, require little maintenance, and passengers are their own drivers - they make sense, financially.

So why not put them in a suburban area? Unlike a train, this requires no new infrastructure besides some electrical outlets here and there. Unlike a bus, you don't have to have 20 people on each ride to break even. Deploying such a system involves less revolving sunk costs - and less financial risk than current mass-transit systems. It also involves more manageable logistics.

Lithium-ion batteries can take you pretty far, particularly in a car this small / light - and considering that you'd only be worried about one-way range (if your rental only has 20 miles of juice and you need to take a trip 14 miles away, just pickup a new one for the trip home).

Sure, this technology is not a fix all - but nothing really is. It does, however, have its place in a broad number of applications and dismissing it with little real argument is premature.

Because the number of possible destinations is greater than the city, but there will be fewer people in a given area using it. So in short, it's a density issue. It's the same reason why taxis don't operate in the suburbs the same way they do in a big city: you have to call one to pick you up - and the rates are higher - as opposed to hailing a passing one on the street.

I'm all for innovation, but I'm also a bit jaded when it comes to "breakthroughs" that never pan out.

But I could be wrong...
