VECTO: Comparison of the conformity of aerodynamic resistance in Europe and the US

In the light of discussion on a new test procedure for truck CO2 emissions (VECTO), this study commissioned by T&E compares the test procedures in the US and EU to measure the aerodynamic resistance of trucks and what tolerances can be used. The research concludes that the 10% tolerance currently discussed for VECTO should clearly be adjusted downwards and therefore suggests a maximum tolerance of 5%.
