New Technology Ready for the American Car Market
These Electrics All Have Drawbacks, But All Increase Efficiency

Three new electric cars are about to hit the market: the Tesla Roadster Sport, the Nissan Leaf, and the Chevy Volt.
The Tesla Roadster Sport drives like a racecar, going from zero to sixty miles-per-hour in under four seconds. Manufactured by Tesla Motors, the Roadster Sport features a carbon fiber body and is completely electric. Although the carbon fiber body is five times stronger than steel, it is also very light, which increases fuel efficiency. However, during a test drive the Tesla Roadster produced wind noise and rattled and shook if it hit a pothole. The Tesla Roadster Sport costs around $128,500.
The Nissan Leaf is also completely electric, but this is more of a family car. It takes eight hours to charge the battery and can be driven approximately 100 miles per charge. Critics worry that the Leaf will run out of juice on a trip and leave drivers stranded. The Nissan Leaf is priced only slightly higher than most average family sedans at around $40,000.
The Chevy Volt is a hybrid vehicle, so it can run longer than the Leaf, but it still features higher fuel efficiency than any average car. Even though it has lithium-ion batteries that run for only 40 miles, it also is equipped with a small gas engine that recharges the batteries while in use. With Volt’s gas engine, this car can travel 300 miles further than a purely electric car. The Volt, manufactured by General Motors, is also in the $40,000 price range.
Manufacturers know that people are interested in electric cars. These vehicles are green, fuel-efficient, and save owners money over time. However, the technology developed to date isn’t perfect and the cost of these cars is too high for the average consumer.
