If you know about the Indian car maker Reva, it's probably becasue of the G-Wiz, that tiny icon of the EV scene (if you're not familiar with the G-Wiz, this is the place to start). In October, Reva's chief technology officer, Chetan Maini, told Business Green that the company hopes to ramp up production capacity to 30,000 vehicles a year. This is a tall order, as the Hindu Businessline says that Reva expects to sell just 750 cars this year. So, what's so bright on Reva's horizon that has the CTO so confident? One new model a year for the next thee or four years (and these will be larger vehicles - how could they be smaller?), the possibility of moving to a battery leasing scheme, and modular concepts that will allow Reva to build the new models without the seven year-long R&D period that the G-Wiz had.
