[2] As of March 2019[update], the organisation considers only energy used while driving, however it plans to expand testing procedures further, in order to cover the entire life-cycle of the car as well as the range of the electric vehicles.
The first one is a test on the chassis dynamometer, adhering to the WLTP procedure, with a slight modification: temperature is set to 14 °C (57 °F), which is close to European average, and the vehicle has lights, air conditioning and other typical systems turned on, while also carrying a realistic payload.
Expanded testing conditions include driving at altitudes from 0 to 1300 metres above sea level, and ambient temperatures from −7 to 35 °C (19 to 95 °F).
[5] They assumed a vehicle lifetime of 16 years, a total driven distance of 240,000 km (149,000 miles) and forecast the average energy mix of the 27 European Union member states plus the United Kingdom.
The battery production emission estimates were reviewed by Joanneum Research and could be traced back to a problem with a data interface, and clarifications on the testing procedures were provided by Green NCAP.
