“Are you ready?” the young driver beside me asked, as we sat in the two-seat Tesla Roadster convertible, facing a straight, steep, quarter-mile road that rises from the water of San Francisco Bay up the headland to the Golden Gate Bridge. Then he floored the accelerator. I was driven into the seat-back behind me—and I mean driven, like I was strapped into some insane amusement park ride—for several full seconds as the car accelerated and accelerated like a rocket up the climb. Only there was no screaming flame blasting behind us. There was no engine roaring either. I was being shot up this road so fast my emergency senses were on full alert, yet all was eerily quiet.
The Tesla Motors roadster is an all-electric vehicle. Which means zero emissions. There’s no engine, no fuel tank, just a deep bank of lithium-ion batteries and a single-gear, direct-drive motor that hits maximum torque instantly (that’s the beauty of electric propulsion). The car is blistering fast; the sport edition goes from zero to 60 miles per hour in 3.7 seconds. Not up on car specs? The Chevy Corvette, with a monster 6.2 liter, eight cylinder, 430 horsepower engine takes 4.6 seconds. The Tesla accelerates faster than the Porsche 911. Faster than the Ferrari Spider. The typical sedan takes a good 6.0 seconds or more to reach the same speed.

The Obama administration unveiled a plan to boost fuel efficiency standards for cars and trucks to an average of 35.5 miles per gallon by 2016—four years ahead of current schedule and up from an average of just 25 miles per gallon today.
The new standards (pdf) will also impose—for the first time ever—a limit on greenhouse gas emissions from vehicles at 250 grams per mile in 2016 under the new proposed rule. (That’s about 5.5 ounces per kilometer, for those of you who like your units mixed differently.)
There are very few vehicles capable of meeting the new standards today, which would mean more hybrids and possibly even electric or other alternative vehicles would have to hit the road within seven years for automakers to comply.

Many have wondered what Better Place's vaunted automated battery changing stations might look like. So the company, a would-be pioneer in electric cars and their attendant infrastructure, has released a slick video showing how it’s done at a demonstration site in Yokohama, Japan.
Swapping out the discharged battery from an electric Nissan SUV for a fully charged one took slightly more than a minute, according to the video, or less time than it might take you to gas up your car. And you wouldn't even have to get out (talk about full service).

After providing some teaser shots, Tesla Motors yesterday let everyone get an eyeful of the new Model S, the company’s $57,400 all-electric new prototype vehicle. Like its sports car cousin, the $109,000 Roadster, the Model S relies on lithium ion batteries for its juice, giving the auto a top range of 300 miles (482 kilometers) after a 45-minute charge, the company says. The need for speed has not been neglected: The Model S reportedly revs up from zero to 60 in 5.5 seconds.
It’s heady days for electric and hybrid car manufacturers and consumers. Last week, President Obama announced $2.4 billion in research grants for the next generation of plug-in electric cars, with funding going to battery work and electric car repair technician training, as well as to efforts such as the development of truck stop charging stations, according to a Department of Energy press release.

CAMBRIDGE, MASS.—By 2030, the people of the world will be driving as many as two billion cars—up from 700 million today—according to John Viera, director of sustainable business strategies for Ford Motor Company. Whether those cars are plug-in hybrids, hydrogen fuel cell vehicles or just supremely efficient internal combustion engines, the economic, environmental and social impacts will be huge—from lithium mining in Bolivia to road rage in China.
