According to Autoweek, the New European Driving Cycle is much gentler in testing with a different driving style from American standards. Testing involves more idle time, constant cruising speeds and much gentler acceleration.
The U.S., however, uses more aggressive acceleration and combines highway and city segments. It also incorporates running the air conditioning during its tests. The two styles paint different pictures of how the Bolt EV and Ampera-e will be treated in their home markets.
But, it also gives Opel some intense marketing firepower.
