FRANKFURT, Germany » The race is on among the world's auto companies to make electric cars go farther on a single charge, bring the price down to compete with gas-powered vehicles and give drivers more places to recharge them than just the family garage.

Electric is the big buzz at the 63rd Frankfurt Auto Show this week, and nearly every major automaker has at least one on display. Renault introduced no fewer than four electric models, while Tesla, the only company producing and selling purely electric cars, handed over the keys to its 700th all-electric vehicle, a blue Roadster Sport, to a German buyer at the show.

Europe is likely to get charging networks faster than the U.S. because of its higher gasoline prices, greater population density and compact size compared with the United States.

In the U.S., Japan's Nissan Motor Co. has taken the lead, forming partnerships to bring electric vehicles and charging stations to Seattle, Tennessee, Oregon and elsewhere. For example, Arizona's Electric Transportation Engineering Corp. recently struck a $100 million deal to build charging stations for Nissan's planned Leaf electric car.

Elsewhere, Renault Nissan has teamed up with Palo Alto, Calif.-based Better Place, which is building a network of charging stations and stands in Israel and Denmark and plans to do the same in Australia. Drivers will be able to plug their cars in or swap out their depleted batteries for freshly charged ones.

Better Place, which has plans to launch a mass-market electric vehicle system in Hawaii, said the networks could operate like cell phone service, with customers buying a certain number of miles in advance or getting an unlimited amount for a set fee with a contract.

To help bring Germany up to speed, its government plans to spend some 500 million euros ($730 million) on a plan that aims to put 1 million electric cars on the road by 2020.

If the models unveiled at yesterday's auto show are any indication, the notion of electric cars as small, stunted boxes with little range is about to be junked.

“;People have realized that ... electric vehicles don't have to be golf carts,”; said Diarmuid O'Connell, vice president of business development for Tesla Motors Inc. “;They don't have to be anemic little putt-putts.”;

The company's sleek, two-seat Roadster sells for $101,500 in the U.S. and has a range of 244 miles on one charge. Its planned Model S, which will seat seven and has a 300-mile range, will go for $49,900.

Others automakers, including BMW, General Motors and Daimler, are also developing electric-powered vehicles, including hybrid cars that boast a small gas or diesel engine backed up with an electrical motor, and say the prices will drop as bulky batteries become smaller, faster to charge and easier to replace.

Daimler said it will put its first electricity generating fuel-cell car on the road by the end of this year, the B-Class F-Cell.

It will also develop a high-performance electric sports car, its Mercedes-Benz SLS AMG.
