From the Editors of E/The Environmental MagazineWhatever Happened to Electric Cars?Hybrids are on the road, electrics in the labsI’m familiar with the hybrid cars now widely available, but whatever happened to the purely electric cars that were around 10 years ago?—Peter Zilly, Bellingham, Wash.The main problem with the electric cars — which reared their heads briefly a decade ago — was their ability to only go so far on battery power. Charges lasted just 50 miles or so, so you were in trouble if you needed to go farther or ran out of juice somewhere in between electric outlets. Hybrids — which have side-by-side electric and gas motors — never need to be plugged in and instead use the motions of their gas-powered engines (as well as those of the car’s wheels and brakes) to keep their batteries charged at all times. With a huge infrastructure of gas stations, refueling is always as easy as pulling over to fill up. Electric car advocates have long touted their alternative vehicles as primarily short-distance commuter cars. At a 50-mile range, most electric cars could make such short trips without recharging. You’d plug the vehicle into an electric outlet in the garage overnight to charge up the battery for the morning commute, then plug it in at the office for the return trip later. But most people want more from their cars than just the daily commute — and gassing up takes minutes whereas re-charging takes hours — so sufficient demand never materialized. Hybrids, though they do use gasoline — are as versatile as conventional cars, and the coming plug-in hybrids promise to substantially increase efficiency, to perhaps 100 miles per gallon or more, by using the electric motor exclusively for short runs and commutes and the gas engine only for long trips. All-electric vehicles are not in vogue, but innovative engineers are busy working to improve them. Technological advances in battery life and engine efficiency mean that electric vehicles may be able to roam farther than ever before. According to EVWorld.com, drivers looking to go electric will soon have a few options: • California-based Tesla Motors will soon be accepting deposits on orders for its Tesla Roadster and plans its first deliveries for 2007. Tesla claims its car can go 250 miles on a charge, which can even be extended further through its regenerative-braking technology, similar to that which is employed in the hybrids. • Spokane, Washington’s Commuter Car Corporation is taking orders for its Tango 600 (a kit you have to assemble) and its Tango 100 and 200 models (fully assembled), with plans to deliver by 2007. Actor George Clooney was Commuter Car’s first customer. The Tango can only go 60-80 miles on a charge but boasts of its ability to go zero to 60 in four seconds and attain a top speed of 150 miles per hour. • Elsewhere, California-based AC Propulsion is working with Toyota on a Scion electric conversion, and Cleanova, based in France, is developing an electric Renault Kangoo, a popular European car. One consideration to keep in mind about electric vehicles is that, if your utility is a dirty coal-fired plant, tapping that power could mean creating more pollution than driving a gasoline-powered car. But progress in renewable energies may well solve that problem and help usher in a new era for electric vehicles.
