Electric cars perform as well as they are designed to do. Those built in the 1970's and 1980's tended to focus on energy conservation, and therefore tended to use less-powerful drivetrains than contemporary gasoline-powered cars in order to reduce power consumption. This has tended to give all electric cars a reputation for having sluggish acceleration and low maximum speeds. Well, that does not have to be the case - EVs can be designed and built for performance rather than energy conservation. Check out some of the following items.

The Silent Supercar
Is a low-volume electric supercar on the horizon? Yes, if there's sufficient demand for the car, says U.K.-based Zytek Automotive Ltd., which has developed an attention-grabbing electric Lotus Elise prototype with support from Group Lotus Ltd.
Both gas and electric versions of the Elise boast a featherweight 155-pound extruded aluminum space frame and lightweight composite body shell. Curb weight is just 1,930 pounds, including batteries -- a full 1,000 pounds lighter than GM's EV1.
Its supercar-like acceleration is estimated at 0 to 90 mph in just 11.2 seconds, quicker than the standard Elise. A 300-volt nickel-cadmium battery pack is said to offer a 120-mile driving range and a one-hour recharge to 95 percent. Top speed is electronically limited to 90 mph.
The impressive power is provided by twin 100-horsepower (75-kilowatt) oil-cooled Zytek brushless DC motors, each mounted to single-speed aluminum gearboxes that transmit power to the rear wheels via equal -lenght driveshafts.
The car is reportedly headed back to Lotus for ride and handling refinements. If produced for sale, the electric Lotus would cost about the same as the standard Elise, batteries not included.

"Current Eliminator IV" an electric dragster owned and driven by Dennis Bérubé, has achieved a 1/4-mile elapsed time of 8.801 seconds. This is the successor vehicle to one that has beaten race-prepared Dodge Vipers in the quarter mile.
