Display more information about Segments & Consumption hypothesis #2

Open FelixLC opened 2 years ago

FelixLC commented 2 years ago

Hello @PatrickNLT , great tool ! I think this table, or a link to what are the segment would be great to give some information on what type of vehicle to choose, because I know the mean consumption of my car but not the segment in which it is supposed to be. And in truth, my car, although vaguely considered as an SUV, has the consumption of the smallest cars (6L/km), so it changes completely the picture :)

Also, you could indicate the EPA size class with examples from https://en.wikipedia.org/wiki/Car_classification#Summary_of_classifications

Thank you @FelixLC. We got this feedback a lot during the test phase. Segments are very arbitrary indeed, and not many people know what they mean. But they serve as the foundation of the study we based the model on.

We should totally provide more examples. Either with the EPA size class of even with actual car models. But then you have to do a conversion between the official WLTP consumption and the actual one. Models exist for this conversion, but we haven't made our mind on this topic yet. :)

BTW I am curious to know what model of car you have. Because 6L/km for a gasoline car is pretty good.

FelixLC commented 2 years ago

Well 6L/km is actually huge ahah, but 6.4 per 100km as I meant obviously, is pretty good indeed, for a VW TROC, which is tagged urban SUV. But respecting the limitations, regular checkups and eco-driving allowed me to stay on this mean for the last 4 thousand km! I still suffer from SUV bashing due to its size but I know I did the best choice in terms of "cm3 of trunk / CO2" which was my main variable to optimize 😃
