I am not in favour of big luxury cars. Public transit methods are good, sustainable and provide more jobs. But there is a myth about electric vehicles. Poeple say, they are very poor in performance and power. May be they are still thinking about the electric cars of 1900s. But time has changed.
So I want to show one of that car. Its Tesla Roadster. What Tesla people says that if you buy this car the money will help them for the research of cheaper passenger cars.
Acceleration & Torque
How powerful is the acceleration? A quick story to illustrate. A favorite trick here at Tesla Motors is to invite a passenger along and ask him to turn on the radio. At the precise moment we ask, we accelerate. Our passenger simply can’t sit forward enough to reach the dials. But who needs music when you’re experiencing such a symphony of motion.
100% Torque, 100% of the Time
The Tesla Roadster delivers full availability of performance every moment you are in the car, even while at a stoplight. Its peak torque begins at 0 rpm and stays powerful at 14,000 rpm.
This is the precise opposite of what you experience with a gasoline engine, which has very little torque at a low rpm and only reaches peak torque in a narrow rpm range. This forces you to make frequent gear changes to maintain optimal torque. With the Tesla Roadster, you get great acceleration and the highest energy efficiency at the same time. All while requiring no special driving skills to enjoy it. This makes the Tesla Roadster six times as efficient as the best sports cars while producing one-tenth of the pollution.

Electric cars equal freedom. Not simply from oil reliance, but from dependence on any specific power source. Electric power can be generated from natural gas, coal, solar, wind, hydro, and nuclear sources — or a combination of all of them — without changing the design of the car. No matter how or when the world changes, the car adapts, making it immune from obsolescence.
We foresee a day when all cars run on electric power and when people will struggle to remember a time when a love of driving came with a side order of guilt.
