Ever since I saw a REVA a few years ago, I’ve been intrigued by it. The REVA takes the word compact to another level, but has that whole Love Bug [1} kinda feel to it. You’ve probably sighted a REVA, especially if you live in Bangalore. (Their website says that the cars are available in six cities.)
The car’s supposed to be able to accommodate two adults and two minors and I’ve seen people driving with kids in their back seat, so it works for some. I’ve never been inside the Reva so I can’t say if it’s comfortable, especially if you’re somewhat tall, like I am. 
The whole idea of an electric car which doesn’t spew out fragrant smoke and fumes is nice. Environmental brownie points. And, if you ask about the economics, here’s an answer from their website , but what the heck, they’re not paying me anyway:
The REVA uses 9 units of electricity for a single full charge that gives up to * 80 KM in city driving conditions. This works out to 40 paise per km (less than 1 US cent). The average running cost of a petrol car is Rs.4.0 per km.
Since the REVA does not have an engine, clutch or gears, or a carburetor, radiator, exhaust etc, the maintenance cost is low. Estimates show that the maintenance costs of REVA are 40 % lower than that of a small car over a 3-year ownership period.
REVA is the cheapest commercially produced electric car in the world.
They talk about the charging system as well and it seems like you’d need to have a garage or be near a socket, so that’s a bit of a constrait.
It has an on- board charger along with a charge cable and can be charged anywhere, at home or at work, by simply plugging in to a 220 Volt, 15-Ampere socket. A full charge a attained in 5 hours and 80% charge in 2 and a half hours.
I don’t know when I’ll be able to get a REVA. If you’re one of those cool people who owns one and wants to give me a ride, I’m game.
I promise to fold my legs and hold my tongue. Till I get to my blog that is.
: For all you VW Beatle fans, I am not comparing the REVA to the VW Beatle.
: To be fair, it is meant to be a city car and probably for nuclear families and not meant to ferry around luggage and twenty people. Get an Ambassador if you want that.
