An electric car is, quite simply, an automobile that is powered by electricity. An electric car has an electric motor and a controller for energising the motor. The energy is stored in its rechargeable batteries, which are re-energized by household electricity. That the electric car is 170 years old may sound surprising, but electric cars predate automobiles with a combustion engine. At first, the electric car was the more popular, but at the time a battery did not exist that would allow a car to move with much speed or over a long distance. However the electric car today still faces the same - fundamental - problems. Electric cars are once again started coming to the top of the media talk and this time the technology is better and batteries are improving. Electric car models, I am sure, will eventually serve as a viable option to conventional combustion-powered vehicles in the near future. Quite how close that "near future" is still open for discussion. Whilst electric car technology has vastly improved over the last two decades there are still two major sticking points preventing the wider use of electric cars:
- Battery technology, particularly the capacity and recharging regime.
- Cost of purchase.
This article is an attempt to address the first of these problems in a simple easily understood manner.
Battery Technology Batteries store electricity in a chemical form, inside a closed-energy system. They can be re-charged and re-used as a power source in appliances or in our case; electric cars. The technology of batteries has moved on from Lead Acid to Lithium Ion with its inherent advantages of lighter weight and higher open circuit voltage. There is an additional advantage which is that they can be manufactured in a variety of shapes and sizes such that installation is easier into an irregular volume that might be found in a car. The final advantage is that they have no memory and no scheduled cycling is required to prolong the battery's life. Manufacturers are relentlessly improving lithium-ion technology with new and improved chemical combinations.
The disadvantages include the cost and availability of Lithium and hence the batteries themselves, and also the life expectancy of such batteries.
A new exciting development in battery technology is the use of Carbon Nanotubes. These are sub microscopic structures. They are just billionths of a metre in diameter. Carbon Nanotubes resemble honeycombs. Scientists have been examining the properties of these for some years and have found that Nanotube material can exhibit the property of a capacitor with extraordinarily high energy density. Quite how long it will take for this to be translated into an available (and cheap) battery which can be utilised in an electric car is anyone's guess.
The second associated question concerning batteries is just how do we recharge them?
Because of the short range - less than 100 miles with current technology - and lack of recharging facilities the use of electric cars is necessarily limited. I believe that electrics will serve a niche market for local driving by a few people. It won't serve the needs for those with long commute distances or even local on-the-road workers. Whilst I might drive only 5 miles to work and back each day or 10 miles to the supermarket or the gym, visiting friends and family some distance away will be unachievable. Additionally even if the expected range of my electric car is 100 miles between recharges because of the lack of suitable recharging points I would be reluctant to risk running out of power before I could return home. As urbanization continues the electric car will be suitable for city travel where distances are short and the range of an electric car needs to be several times the daily mileage driven.
What is the solution? The technology to make an electric car that could be charged almost anywhere is already here - it simply hasn't made it to the market. The proposal to create "charging stations" seems to have missed the point. Just plug it into your domestic socket and leave it overnight.
Another solution which might be feasible in the short term as a concept is the battery that can be swapped out at "electric filling stations" Pull in like we do at petrol stations and the station attendant simply swaps out your battery with a recharged one. This could be the solution for the long distance road travel.
We’ve compiled a list, below, of 27 (update: the list has reached 30; thanks for the comments) startups, listed according to their release date, with additional information on fuel type, range, top speed and price. Most haven’t yet taken venture funding, but where applicable, we’ve listed financial backing.
While we’ve got some overall favorites (Miles, Tesla, Think) and a few favorite oddballs (Aptera, Commuter Cars, Eliica), we’ve for the most part withheld judgement. Still, if you have any of your own predictions about which companies will succeed or — far more likely — fail, we’d encourage you to make them known in the comments.
A note on our method: While most manufacturers are planning more than one model, we chose the one that seemed either most commercially viable or closest to release, depending on our own (discretionary) formula. We didn’t included well-known consumer models like the Toyota Prius or Chevy Volt, or startups like AC Propulsion that only do battery conversions for consumer vehicles. We also rounded the price to the nearest thousand.
All details are taken from the companies, so we haven’t independently confirmed things like range and top speed details. In case we missed any, mention them below and we’ll add them to the list.
American Electric Vehicle — Kurrent
Update: Defunct, according to a comment below, although they seem to still be for sale. We’re looking into it.
AEV advises its potential drivers to “Slow down,” which seems like wise advice, given the golf cart-inspired design. Still, it’s ridiculously cheap.
Fuel type: All-electric
Price: $10K
Range / top speed: 40 miles / 25mph
Release date: Available now
Commuter Cars — Tango T600
The Tango is even odder than three-wheeled designs, in some ways: It’s less than half the width of a normal car, and two can fit in a single lane. It also accelerates like a bat out of hell. Future versions are planned to be much cheaper, and have longer ranges.
Fuel type: All-electric
Price: $108K
Range / top speed: 80 miles / 150mph
Funding: Less than $1 million in angel backing; open to venture funding.
Release date: Available now
Dynasty Electric Car Corp. — IT Sedan
This Canadian company actually sells five different models, although they all look relatively identical, minus or plus a few pieces of frame.
Fuel type: All-electric
Price: $19,000
Range / top speed: 30 miles / 24mph
Release date: Available now
ElBil Norge — Kewet Buddy
Somewhat reminiscent of the Think (see below), the Buddy is currently only available in the same country, Norway.
Fuel type: All-electric
Price: $28K
Range / top speed: / 56mph
Release date: Available now
Fly Bo — 6000 / 2
This vehicle, which bears a strong resemblance to the Smart Car, is produced in China. Spark (see below) distributes it in the United States.
Fuel type: All-electric
Price: $10K
Range / top speed: 60 miles / 35mph (w/ limiter)
Release date: Available now
Global Electric Motorcars (GEM) — e2
GEM is actually a division of Chrysler, the company has the look and feel (not to mention, apparently, the limited funding) of a startup. Its vehicles resemble golf carts, and are likely used for many of the same functions.
Fuel type: All-electric
Price: $7K
Range / top speed: 35 miles / 25mph
Release date: Available now
Modec — Electric Van
These aren’t actually cars, or even consumer transportation. These electric van / trucks resemble the delivery vehicles you might see bringing vegetables to your local grocery.
Fuel type: All-electric
Price: $41K
Range / top speed: 100 miles / 50mph
Release date: Available now
Myers Motors — NmG (No more Gas)
Another three-wheeled design, with room for only one passenger. Odd-looking and doesn’t go far, but you can order one today, if you like.
Fuel type: All-electric
Price: $35K
Range / top speed: 30 miles / 75mph
Release date: Available now
Reva — G-Wiz
Despite its distinction as the most-produced electric vehicle around, having been in production since 2001, the Indian-produced Reva isn’t available yet in the United States. It’s considered extremely unsafe at high speeds, so it may never make it over.
Fuel type: All-electric
Price: £8K ($16K in US dollars)
Range / top speed: 70 miles (for 2008 model) / 45mph
Release date: Available now
Smith Electric Vehicles — Edison
The Edison, a large van designed for local deliveries, is Smith’s smallest model, meaning drivers don’t need a special license to operate it. The company, based in the United Kingdom also makes several much larger delivery trucks.
Fuel type: All-electric
Price: Unconfirmed
Range / top speed: 150 miles / 50mph
Release date: Available now
Twike — The Twike
Some effort seems to have been put towards making this vehicle look like an insect. Of course, the look worked for the Volkswagen Beetle, and it may be working for Twike; the company sold out its 2007 line last year. It’s based in Switzerland, but sells in several other countries, including the United States.
Fuel type: All-electric
Price: $27,500
Range / top speed: 80 miles / 53mph
Release date: Available now
Venturi — Fetish
Another high-end electric sports car, the Fetish is manufactured in Monaco. High labor costs, anyone? The company is also developing two more models, the Ecletic and Astrolab.
Fuel type: All-electric
Price: €297K (about $435K dollars)
Range / top speed: 155 miles / 100mph
Release date: Available now
Zap! Electric Cars — Xebra Sedan
Update: While Zap! cars really do exist, the company appears to have made itself out to be much more than it is. Check out the Wired.com expose piece on Zap, and think twice before ordering one (or signing up to be a dealer).
We chose to list the Xebra because the two higher-powered versions Zap is working on, the Zap-X and the Alias, don’t have firm release dates. Zap also has numerous retail locations in the United States, and sells cars made by other manufacturers.
Fuel type: All-electric
Price: $11K
Range / top speed:
Release date: Available now
Zenn Motors — Zenn NEV (Neighborhood Electric Vehicle)
As with some other available electric vehicles currently available, this vehicle is strictly for short ranges and slow speeds.
Fuel type: All-electric

Range / top speed: 35 miles / 25mph
Funding: This company is publicly traded on the TSX.
Release date: Available now
Lightning Car Company — Lightning GT
The United Kingdom’s answer to Tesla. This will likely remain a boutique vehicle, but the company has plans for cheaper mass-produced models later.
Fuel type: All-electric
Price: £150K ($293K in US dollars)
Range / top speed: 250 miles / TBA (but fast)
Release date: First half 2008
Spark Electric Vehicles — Comet
Update: Like Zap (see above), it seems Spark is either a scam company or simply incapable of carrying out its plans. Michael Papp, the brain behind Spark, has been arrested and faces trial for taking payments for vehicles he failed to deliver.
Spark has nine models, most made by Fly Bo (listed above). Here, we list the one they designed and manufactured themselves in the United States (most of their vehicles are much slower and cheaper than this one). They distribute their vehicles in Colorado, Michigan, New Jersey and Pennsylvania.
Fuel type: All-electric
Price: $33K
Range / top speed: 200 miles / 90mph
Release date: First half of 2008

Backing: Kleiner Perkins Caufield & Byers has invested more than $10 million in Fisker.
Release date: Mid-2009
Venture Vehicles — VentureOne e50 / Q100 / EV
We previously suggested that some might call this vehicle a “glorified scooter.” The company does have supporters, though, who gave us plenty of heat — for a chuckle, check out the comment thread below our story. The three models listed are actually one car with different configurations.
Fuel type: Two hybrids, the e50 and Q100, and the all-electric EV
Price: $20K – 25K

Release date: Second quarter 2009
Miles Electric Vehicles — XS500
Founded in 2004, this company already makes and sells two low-speed electric vehicles which are manufactured in China. We chose to list details for its upcoming highway-speed model, which should have a mass market appeal, if the price is low enough.
Fuel type: All-electric
Price: TBA
Range / top speed: 120 miles / 80mph
Release date: 2009 (month TBA)
Bonus: Concept cars
We’ve picked out a few companies that represent next-generation thinking in EVs. As noted below, there are many more.
Eliica (The Electric Lithium-Ion Car)
A concept car created by Keio University in Japan, the Eliica has an odd eight-wheeled design and has come close to breaking speed records for combustion-engine cars. The team plans to sell a couple hundred eventually.
Fuel type: All-electric
Price: $255K
Range / top speed: TBA / 230mph
Velozzi
An X-Prize contestant, Velozzi is most notable for claiming that their car will have a 0-60mph acceleration of under 3 seconds. Other details are pretty thin, though.
Fuel type: Hybrid
Price: TBA
Range / top speed: TBA / 200mph
Wrightspeed — X-1
Wrightspeed admits that its scarily fast prototype is unsafe, and will never be mass-produced. The company is planning a commercial model with the same high performance, but hasn’t given any real details yet.
Fuel type: All-electric
Price: Probably high
Range / top speed: <100>
There’s also the Automotive X-Prize competitor list, which had grown to 45 teams at last count — a few of which are included on this list, but many not. Most are concept cars.
Favorites? Least favorites? Think they’ll all fail horribly? Speak your piece.
