Tesla Model S: Finally, A Worthier Successor to the Gasoline Car [video]

Tesla has overcome two of the key drawbacks to electric cars: range and recharge time.
In last few years, however hard the electric car designers try to design and sell best cars, they lack on two important tasks, which are the distance electric vehicle can travel in a single charge and the charging time. Anything beyond 200 km range was becoming challenging and the charging time anything less than 1.5 hours was also tough to design. But now you have a beautiful luxury sedan electric car from Tesla motors, the Model S, which can travel 480 KMs in a single charge and in 20 minutes the car can be recharged to travel another 200+ KMs. A range beyond this is not required for most of the users. It is a pretty cool performance for an electric car to compete with internal combustion engine cars. The technology behind this achievement is use of advanced lithium based and other fast charging high-density batteries coupled with super capacitors. Super capacitors can be charged faster which can charge the lithium batteries while the car is moving.
While electric cars having able to come out of these drawbacks, the other inherent advantages of electric cars seduce car buyers to go for electric. The Tesla's Model S has received high-ranking for safety by safety testing organisations in the world. Due to the placement of batteries on the bottom floor of the chassis, the electric cars offer excellent centre of gravity. At higher speeds electric cars hold onto the road far better than a petrol/diesel cars while negotiating curves. These clutch-free vehicles is easy to drive. And also due to electric control of motion, making electric cars self driving is lot easier.
But there's still one drawback. The cost of the electric car in most of the regions is high compared to traditional car. The Model S from Tesla costs close to US dollar 60,000. In India Mahindra Reva is offering its new e2o model at a cost of little more than US$10,000. This not so-expensive car is limited with lesser mileage of 100 kilometres and the charging time of two hours. Over next 3-5 years, most of electric cars will employ the technology to increase driving range and also reduce charging time. The cost of the electric cars to come down as the volumes rise. The cost per km is also expected to come down due to decrease in average selling price of Lithium based batteries and supercapacitors.
