Greenhouse gas emissions are currently one of the most important concerns worldwide, as they require an immediate response before a point of no return. Regulatory organisms in the automotive sector in Europe have developed new regulations (WLTP and RDE) that are much stricter than the old NEDC, thus trying to avoid scandals such as the "Dieselgate": This paper analyses, with the help of the amended regulations, the energy consumed by two different vehicles in two different situations. On one hand, 4 RDE (Real Driving Emissions) routes are designed where the energy impact generated by curved paths is analysed. In the second case, two deceleration tests, called "Coast-down", are analysed. In one test a strictly straight trajectory will be used, while in the second test a only curved trajectory will be used. From this, the different behaviours in both situations are analysed and the energy consumed difference will be obtained. In order to achieve the established objectives, the analysis part is done using MATLAB, always taking into account current and future regulations. The work is carried out in the facilities of Applus IDIADA, where the tests are designed, prepared and carried out with their knowledge of 25 years offering emission approval services.
