Don’t double post, just edit the previous post.
Read the briefering of the stage, in this age, cars needs to comply fuel emissions and fuel economy, specially in a eco friendly country as it is Fruinia. Also there exist in real life certain fuel economy that new cars needs to meet, but it is divided in car size, one for small cars and other for bigger cars (which include muscle cars), in the US, only big trucks are excented of that. In a side note, also there is certain average fuel economy that a company needs to meet in their entire line-up.
In the gameplay of the challenge, the minimum required fuel economy, the required emissions and the minimum reliability are there to avoid people sending ridiculously cars with 15 reliability, 3 MPGs and 567643656 hp marketed as “road legal”. Plus it makes a harder challenge.
I guess you have to figure out what “better fuel economy than” means.
So, I told you “don’t double post” and then you quote a big block of text with a question not related to what you ask?
And it is working, you need to download it, then you can edit it in excel or google docs.
I just downloaded from both a pc and my phone and it worked.
It is not thaaat hard actually, you can also increase slightly the weight of the car to get a more reasonable fuel economy. Big displacement (undersquare), 4 barrel and a not so extreme fuel mixture should give you something close without the use of electronic wizardry. It helps if the cruise rpm is close to the max fuel efficient point of the engine. That said, all of that might compromise the power and speed of the car.
