Consumption gain 130 -> 110

From this graph, by graphical deduction (we have not yet gone back to the study data, page 151 figure 26), we find the data below.

Diesel: 6.5 l/100 at 130km/h -> 4.75 at 110km/h

Gasoline: 11.75 l/100 at 130km/h -> 8.65 at 110km/h

So -27% in diesel and -26% in petrol by going from 130 to 110. We keep the order of magnitude of 25%.

This calculation should be refined. Some sources to investigate for the calculation.

• a citizen who makes his test for a clio. He finds a reduction between -20% and -50% ! https://twitter.com/CptQwark_/status/1289499582871658499 Another citizen finds rather -10% with a bigger car
• ">Report of the CGDD, where we have not found for the moment the explanation of the calculation of CO₂ savings
• Aurélien Bigo who criticizes the CGDD report https://twitter.com/AurelienBigo/status/1276459283291439114, but who does not give us any information about the calculation of the CO₂ itself.
• another evaluation, which gives us the calculation :) : https://twitter.com/Tomsawy22670318/status/1274257122373570565 Attention, to be rigorous, as mentioned in this last thread, it is necessary to take into account the distribution of the speed and the category of car (presence of a 6th gear for example). Obviously, we do not drive at 130 all the time.
