Greener, more frugal versions of Tata Nano on the cards

The Tata Nano continues to make headlines both for the right and wrong reasons since its unveiling at the Delhi AutoExpo in January this year. Land acquisition trouble and rising inflation which has past well over 11% in the country has created a new set of problems for Tata, although the manufacturer is hell-bent on retailing the base model at $2,500 and more importantly on the previously decided dead line of anytime between September and October.

The good news is that Tata is working on multiple variants of the Nano. No, not bumper colors or alloy wheels, by variants, we mean powertrain options. Sources say a battery powered Nano might roll out of the Singur plant in West Bengal very shortly along with air-powered and micro-hybrid (start-stop technology) models.

The compressed air technology would be borrowed from French company MDI, which uses compressed air to push the piston. An onboard compressor pressurizes air which is stored in a tank for use, a technology which works pretty well, and is one of the best alternatives to an electric car.

Otherwise, the Tata Nano uses a 2-cylinder 624 cc engine that produces a little over 30 hp. The tailpipe emissions are minimal and is less than what an average motorcycle in India would emit.
