This paper by the European Automobile Manufacturers’ Association (ACEA) provides an analysis of the CO2‐emission values of heavy‐duty vehicles produced for the European market during the second half of 2019.
- The analysis shows that 68.2% of the CO2 emissions of all analysed vehicles can be attributed to just one subgroup, namely 5‐LH (4×2 tractors, GCW >16t).
- It also reveals that 95% of all vehicles in 5‐LH, the most important subgroup, have CO2‐emission values between 52 g/tkm and 64 g/tkm with an average of 56.5 g/tkm.
- The spread of CO2‐emission values around the average for the 5‐LH subgroup is only +13.3% to ‐8.0%, or about +/‐10%.
- Even though the EU Regulation specifically allows the use of ‘standard values’ under certain conditions, over 90% of all CO2 values determined with VECTO are based on measured component‐input values for all components.
- For each individual component (axles, transmission and air drag) 94‐97% of the CO2 calculations are based on measured input values.
