Which brings up the question of whether it's not already time existing cars (starting at the performance end, and then trickling down to consumer market), should not already be replacing:
(Int. Combustion Engine)---[variable rotational speed/torque]--->drivetrain
with:
ICE---[constant rot. speed & constant torque]-->dynamo--->battery-->fully electric motor(s) drive train.
That would give most of the performance benefits/efficiency of electric motors, with the range of ICE-based vehicles. Since operating at essentially constant torque / speed, the ICE could then itself be made more compact and simplified to reduce the vehicle's weight.
I'm sure the above is already being done or worked on, and maybe someone could point to examples of it.

- briffle 11y agoAs well as any train locomotive built in the last 40 years or so....
- erikpukinskis 11y agoI think the Koenigsegg Regera is a really interesting model: https://www.youtube.com/watch?v=yjWzoJdmPeM https://www.youtube.com/watch?v=yjWzoJdmPeM It uses the battery to get going, and then gradually revvs up the ICE engine, which only has a single speed, as you go faster. You get the growl and power of an engine in its sweet spot with the instant torque of an electric and a dramatically simpler drivetrain, less weight, etc. Supposedly it's amazing to drive, if you have a million dollars.
