But the whole point of this discussion is to evaluate the likely performance of a new aircraft, not the overall performance of the existing fleet. This particular new aircraft is electric, so leaded avgas won't be an issue.

Cherokee 180/181 checking in! $4.09 would be great, $5.12 at my base this morning. $0.35 club discount helps though.

I fly in the south and as long as I'm not at a major airport (in class G) I can get gas pretty cheap. Poking around on some maps I can even find it cheaper.
Really all depends where you fly.
I fly a Cherokee 140. One of the most common aircraft, as with the Skyhawk. My fuel consumption is 8.4gal/hr at 75% mixture and 5.6gal/hr at 50%. Assuming I'm doing an average ground track of 100mph (for easy math), that's 12-18mpg (not counting that I'm 100% rich at TO and LND).
I wouldn't exactly call it fuel efficient, but it isn't burning like an oil refinery on fire either. I also don't pay $5 for gas ($4.09 today, but it isn't uncommon to see it at $3.50). But you do have to consider speed and time to destination if we're going to compare to cars.
One thing to also consider is that avgas is still leaded. And for anyone interested, here is the POH for the Skyhawk[1] and Cherokee[2]. Note that fuel consumption will be in hours or gal/hr when discussing aircraft. Mpg doesn't make as much sense.
