55mpg steady state for a gas engine must require some pretty ridiculous engineering. I can see 55mpg in a plug-in hybrid as long as the battery has charge to assist. But by the time you’re getting 55mpg out of a gas engine without any battery assist, I would imagine it’s a pretty utilitarian driving experience. Certainly an EV driving experience versus a 55mpg ICE is going to be absolutely no comparison.

While maybe not the sportiest things around, 55mpg cars are readily available and are perfectly fine and usable. Example: https://www.auto-data.net/en/volkswagen-passat-b8-facelift-2019-2.0-tdi-150hp-39207 https://www.auto-data.net/en/volkswagen-passat-b8-facelift-2...

  That’s a 150hp diesel engine. US consumers generally don’t buy those, particularly these days. VW doesn’t even sell diesels in the US anymore. The gas engine 2020 Passat gets 24/36 mpg city/highway.

> Certainly an EV driving experience versus a 55mpg ICE is going to be absolutely no comparison. 5 speed properly jetted and carb tuned Honda CRX for MPG or a Geo Metro come to mind to get those numbers and were made in the last century, other than only a K car or 3 cylinder exotic can come close. Did a Smart, which always looked like more like a toy than a car, actually get that? I had an 1st generation CRX in university and that thing was a coffin with 4 wheels as nothing but 2 bodies fit inside. It's nothing I would say was ever comfortable by any stretch of the imagination. I got in a bad accident in that thing due to a mechanical failure on the freeway and I'm surprised I'm still able to walk to this day as I felt every inch of that metal bend and fold upon impact. Ended up with bad hyper extension injuries to my ankle/feet (2 feet in rule in a spin) and vertebrae damage that persist to this day that made me realize MPG is not worth bodily injury. My prius only gets 44 mph with mainly street driving, and its ok but feels like joke when its windy due to how light weight it is.

54.5 "fleet average" MPG is about 40 MPG on the window sticker (EPA test cycle).

  I would have thought passenger cars would have to be even higher than 55mpg to get a “fleet average” of 55. What are the vehicles getting more than 55 such that passenger vehicles can get less?

    EPA MPG that consumers are most familiar with is miles per gallon. Corporate Average Fuel Economy is the harmonic mean. It also gives a divisor of 0.15 for EVs and E85 cars.
