Electric Cars: A Definitive Guide
Electric Cars What Is An Electric Car?
An electric car is powered by an electric motor instead of a gasoline engine. The electric motor gets energy from a controller, which regulates the amount of power—based on the driver’s use of an accelerator pedal. The electric car (also known as electric vehicle or EV) uses energy stored in its rechargeable batteries, which are recharged by common household electricity.

Unlike a hybrid car—which is fueled by gasoline and uses a battery and motor to improve efficiency—an electric car is powered exclusively by electricity. Historically, EVs have not been widely adopted because of limited driving range before needing to be recharged, long recharging times, and a lack of commitment by automakers to produce and market electric cars that have all the creature comforts of gas-powered cars. That’s changing. As battery technology improves—simultaneously increasing energy storage and reducing cost—major automakers are expected to begin introducing a new generation of electric cars.
Electric cars produce no tailpipe emissions, reduce our dependency on oil, and are cheaper to operate. Of course, the process of producing the electricity moves the emissions further upstream to the utility company’s smokestack—but even dirty electricity used in electric cars usually reduces our collective carbon footprint.
Another factor is
convenience: In one trip to the gas station, you can pump 330 kilowatt-hours of energy into a 10-gallon tank. It would take about 9 days to get the same amount of energy from household electric current. Fortunately, it takes hours and not days to recharge an electric car, because it's much more efficient. Speaking of convenience, let's not forget two important points: charging up at home means never going to a gas station—and electric cars require almost none of the maintenance, like oil changes and emissions checks, that internal combustion cars require.
Electric motors develop their highest torque from zero rpms—meaning fast (and silent) zero-to-60 acceleration times.
Note: In the illustration, we show the relative features of electric cars and gas-powered cars. However, it doesn't have to be an "either-or" situation. Plug-in hybrids offer many of the benefits of electric cars while mitigating most of the drawbacks, such as limited driving range.
1New and Upcoming Electric Cars
Just as the major car companies were crushing their electric car programs in 2004 and 2005, the perfect storm was brewing on the horizon: Hurricane Katrina, growing acceptance of global warming, runaway Prius sales, oil price spikes, green marketing galore…The major auto companies went right back to the drawing board and emerged with big plans for electric cars.
BMW Megacity
BMW is working on a small electric car that could launch in 2012. The Megacity is a low-slung three-door four-seat hatchback coupe. The car is smaller than the Honda Fit, and will have a projected range of 100 miles. The BMW Megacity, which could be sold either as a BMW or Mini, is not much more than a concept at this stage, but pressure on BMW to meet California's zero emissions vehicle requirements might bring the car to life—albeit in small numbers.
BYD E6
If China’s BYD can deliver on its big promises for the E6 all-electric crossover, then it could take the US by storm. (Investment guru Warren Buffet is betting that BYD will come through.) Unlike the small city-oriented electric runabouts on slate from established carmakers, the E6 is a five-passenger wagon capable of carting a typical American family. Moreover, the E6 has a range of 200 to 250 miles and boasts a 0 to 60 mph time of less than 10 seconds. Top speed is 100 mph. The vehicle can be fully charged in about 10 hours by plugging into a standard household outlet. BYD says that it takes only 10 minutes to charge to 50 percent capacity and 15 minutes to the 80 percent level. BYD has been in the battery business only since 1995, and started building cars in 2003. Considering that the company maintains an R&D department with 8,000 engineers, it’s not surprising that the initials BYD stand for “Build Your Dreams.”
