The scheduled introduction of EU7 emissions regulations has increased the depth of field for real-world emissions compliance. Whilst EU6 emissions legislation provided clear boundaries by which vehicle and powertrain Original Equipment Manufacturers could develop and calibrate against, the more stringent emissions limits and wider real-world driving test fields of EU7 are more difficult to ensure compliance with. In-house and in-field physical testing to assess emissions compliance of a vehicle and powertrain will not be enough to ensure emissions produced during real-world driving are below the legislative limits. It is likely therefore that OEMs will need to adopt some aspect of virtual engineering to supplement this.
