Moves to introduce electric vehicles as taxicabs are gaining momentum on the back of increasing local government subsidy programs and awareness in the industry of the advantages of such environmentally friendly vehicles.

Cab operators' awareness of the potential of EV taxicabs to improve their image in the eyes of consumers is also behind the growing moves, industry observers said.

Nissan Motor Co. said it has received 6,000 domestic orders for its Leaf electric car, which will be released in December.
