2019 Sample – Updated to economic conditions of December 2024

The variations observed in the survey on the costs and operating conditions of CNG vehicles remain significantly higher than those measured in the CNR Regional surveys on articulated vehicles running on diesel. The average results of the REG EA – CNG survey do not have the same degree of accuracy as those from the CNR's annual surveys on articulated vehicles running on diesel.
The two main reasons for these discrepancies are as follows:

  • Sample size: less important for the REG EA – GNC survey
  • Characteristics of the activity

The operating conditions presented for LNG vehicles relate to specific markets and appear to be highly optimised compared to diesel standards. They are characterised by higher annual vehicle mileage and a greater number of operating days.

The published cost price benchmarks include the accelerated depreciation of vehicles, but exclude subsidies granted by ADEME, which are now obsolete, as well as regional subsidies that are not available everywhere and are too scattered to be representative.
