    14. 14. According to the Business News on 12thApril, 2012, M&M is planning to Launch a full Hybrid Electric Vehicles in India in a couple of Years. http://www.livemint.com/Companies/z400EtgvamnPJZSzDrl5lO/Mahindra-developing-hybrid-vehiclelaunch-in-three-years.html Soon can be seen on Indian Roads.
    15. 15. “Sometimes being different is good enough, you need not be new all the time”  So, the HEVs have more efficiency, Low Fuel Economy, High Reliability and Less Air Pollution.  Optimum Utilization of these Vehicles will yield in good Results, especially Reduction of pollution.  It can prove to be vehicle of future.  If designed well, these hybrids can equal or better the utility, comfort, performance and safety we’ve come to expect, while saving us thousands of dollars at the gas pump.
