This report describes the findings of a non-random selection survey undertaken to assess the performance standard and level of public satisfaction with CNG powered vehicles. A total of 65 vehicles from the Auckland area was evaluated covering most of the popular models and CNG conversion systems. A significant proportion was found to have CNG equipment deficiencies which caused a power difference between petrol and CNG of more than 20%. The majority of these vehicles were capable of being rectified relatively easily. Approximately 75% of the people surveyed were satisfied with the power output of their vehicle. Over half of the vehicles belonging to dissatisfied owners exhibited power differences in excess of 20%. The major complaint, raised by over 25% of the people surveyed, was difficult cold starting on CNG. (ERA citation 11:007426)
