Much before we see a petrol Nano, we already heard of euro speci version, nano diesel, nano hybrid and now Nano micro hybrid. Media reports claims that a micro hybrid variant of Tata Nano would also be launched. Micro Hybrid first brought to India for its Scorpio and Bolero is meant to save fuel during idling. Bosch will supply the kit for Nano. The micro hybrid or start/stop technology will result in increase in price of Nano by Rs4000 – Rs6000.
