ok...maybe I'm an idiot, but is an EV car all electric meaning no gasoline of other fuel? so how do they get a figure of 112 Miles Per Gallon (MPG) in a news article i just read on yahoo? ?.
Answer
We're stuck with MPG for electric cars for the same reason we still use "horsepower" to measure engine power. Engines have little to do with horses, but early car buyers wanted to use a metric they understood - horses.

Electric cars don't burn gas, so there are a couple of different ways to compare electric power to gasoline. The first is called MPGe, and this measurement compares the efficiency of the electric car to the theoretical "kilowatt-hour" equivalent energy stored in a gallon of gas. This is the MPG number you usually see attached to an electric car, it is easy to calculate and use for comparison, but it has little to do with reality.
*
Much more useful is cost-equivalent MPG, in other words, how far can you travel in an electric car for what a gallon of gasoline costs? Unfortunately, this number varies from day to day and from place to place with the changing prices of gasoline and electricity, which is why you never see this number used.

Example: I drive a Chevy Volt. The official MPGe number is 93 MPG. But the cost equivalent MPG for me (using my local electricity and gas prices) is about 190 MPG. Big difference!

I have questions on the world's most cheapest car in Yahoo! news?

Well, it's a very compact car, and I was just wondering if this is a very safe car to purchase. Not just safe as in the pockets, but safe as in the driving.... what do you think? To make my question clearer, what if I were to be in an accident with a regular compact car [like say a toyota], will i be safe when both cars hit impact? Or we're just both screwed? Or my car is just too compact that I will be crushed to my death?
Furthermore, it doesn't have airbags. Of course, by the time they get to exporting the vehicle, they would have to comply to US laws, right?
Answer
I read that article too, very interesting. It appears that the car was designed specifically for India's low income folks, but it would be unlikely to be exported to most "Western" countries due to is lacking many of the required safety functions such as air bags.
If they did import I don't think it is the first time a cheap small car like that would have hit the market. Yugo's and Geo's have all ready come and gone.
