The latest models launched at the 12th Auto Expo 2014 are by now common knowledge among vehicle enthusiasts but few are aware that IIT Delhi has successfully tested India’s first biogas fuelled passenger car.

Compressed biogas was tested on a regular CNG car for over 15,000km. The best news was for the environment — the emissions were lower than CNG. Also, existing CNG vehicles need not undergo any modification to be compatible to CBG.
