Comment on Tesla Cybertruck gets less than 80% of advertised range in YouTuber’s test
andrew_bidlaw@sh.itjust.works 8 months agoThat’s the same for a fuel-based cars. Some other users told me about the black magick trickery electric cars do in the city. Guess you’d like to check their replies too.

Gasoline powered engines are very inefficient in terms of getting all of the potential energy out of it’s fuel source. They do have a sweet spot, usually somewhere between 2,000 and 3,500 rpm and most companies will tune their vehicles to be at highway speeds while in that sweet spot. The rpm range from idle (ICEs needing to idle at stoplights decrease city MPG) up to that sweet spot is less fuel efficient than rolling around in the sweet spot, so a lot of stop and go driving will see a gas motor running out of it’s fuel efficient range quit a bit.
Electric motors have the same efficiency at any rpm and they don’t use energy while the car is sitting still.
