Tata Motor is currently testing the CNG versions of the Winger model in Pune. GoaOnWheels reports that it had no badge or even the cover as it looked a production ready version.
Tata Winger CNG will carry the green sticker on the front door and there were no other exterior changes. The company is facing the heat on fuel prices increase to counter attack the company wanted to reveal the CNG version which will be an alternate.
