The gas mileage seems off. I have a small SUV (Mazda CX3), and since there was no category for that (maybe the small SUV market is too USA-centric), I picked a "Medium car" (lke a VW Golf).

But it gave the gas mileage as 18 mpg, while I get a measured 30 - 32mpg on my commute. Even when I had a golf, I was getting around 25 mpg.

The fuel consumption by vehicle category is based on averages. We didn't put too much energy into accurate measurements because you can change the consumption on the results page so that it exactly matches that of your car.

Average for what? Your number for an "SUV" is 13.6MPG. The worst fuel economy for a 2018 model I could find in the EPA database is 11MPG[1].
