@ Mods I will post it in several sub forums, crossposting because I don’t just want to address a specific car brand. Thank you for understanding. Hello, I would be very happy about a support from you. I am working on the determination of the average efficiency of a petrol engine as well as diesel engine in real driving mode. I just get all the fakenews about the verbenner of alleged 15% efficiency etc.. For this I need a realistic driving prof il. Is nothing but a v-t diagram. So on the X Abzisse the time is applied and on Y then the speed. For example, you can easily create a GPS tracker with your smartphone and then simply follow your everyday life (do not tunnel). First as a privacy notice. I don’t care about your GPS track points, where you could understand where you went. But only the diagram with a small marginal note whether it is in the section around a country road, autobah The WLTP test cycle is of course available, but I think it is completely unrealistic. It is accelerated from the beginning to 45 km/h, either there are apparently 45 zones that I don’t know or someone is driving extremely carefully. Then it is slowed down to 10 km/h, no traffic lights. Of course perhaps dense traffic or a fork in the road. Only it is slowed down several times to 10 km/h during this cycle. Also during overland journeys. That’s why I keep the WLTP for r unrealistic. Would be great if you could create such profiles. In return, I will publish my result with the data. Then you have a sound argumentation basis. Thank you very much.
