An idling gas engine may be annoyingly loud, but that’s the price you pay for having WAY less torque available at a standstill.

You really don’t need 90hp. Coasting on the freeway takes less than 10hp, depending on how big of a block you drive, so as long as the average is around that, the generator can keep the battery charged forever, and the battery handles any surge in power you need. It’s only a problem if you drive like a jerk, and floor it out of every light or speed down the highway at 100+mph, and do it long enough to drain the battery.
But the brilliant part is that you can design the generator motor for single, constant RPM. I can’t emphasize how much easier and more efficient that makes everything, vs. having to engineer a huge power/rpm range that can handle a dynamic load.
No I’m with you and have always kind of wished that’s the direction more EVs would have gone. I have a minivan for all the shit going on with kids and I love it but I have to drive six hundred miles half a dozen times a year so they can visit their mom. A higher range EV that I can refill with gas would be a game changer. Instead I got an electric golf cart that is street legal I use for the majority of my local commuting so I only drive the minivan a few times a week. I was really just being a turd because your first comment said 3 HP and the next one said 5 HP.
