It is also important to note that this is the strongest year-start since mid 2000s: except for January 2012, when number of kits installations was close to January 2013, conversions in each first month of the year had not reached the five figures from 2006 onwards.
Last year, the annual number of vehicle conversions reached 134,324 units, remaining very close to what happened in 2011 (with 140,541 kits) and higher than the previous five years.
Throughout 2012, an average of 11,193 vehicles was converted to natural gas. In addition, CNG kit installations exceeded 10,000 units during eight of the twelve months of last year, with peak in July.
In conclusion, these are the number of CNG conversions last year, month by month: 10,033 in January, 8,301 in February, 12,535 in March, 11,606 in April, 13,084 in May, 12,892 in June, 14,036 in July, 12,843 in August, 9,890 in September, 10,719 in October, 9,627 in November, and 8,758 in December.
