Not really, no, some diminutive sound of bearings and stuff, completely owerwhelmed by the gears. Brushed motors are loud, but they're not relevant to racing. Also peculiar designs like a switched reluctance motor, which apparently yank around the rotor, I never heard of a desire to use those.Tommy Cookers wrote: ↑23 Jul 2025, 11:39so there's no noise from those (electromagnetic) forces cycling hundreds of times a second ?
@mzso and btw for my convenience ...
the energy cost of transporting electricity (before any charging/discharging batteries) is 10% and rising (Ohm's law)
the energy cost of transporting the conventional ICE fuel is 0.2 - 0.5 % (common sense)
in appealing to the FIA we might consider that 'they' have improved F1 ICE efficiency from 29% to 52% in 10 years
(most of this 52% can be retained with NA V10s (Atkinson-ed, recovery turbine-ed, of course)
Not sure what you mean by "10% and rising (Ohm's law)". Or what do you mean by your 0.2-0.5 value.
