Weird, does this apply to EV's, too?

- axiolite 5y ago> does this apply to EV's, too? Not "pumping" losses, no. There is no intake air or exhaust gas to pump. EVs may experience an effect that is similar in practice, albeit much smaller... Things like headlights, HVAC, entertainment systems, etc., will draw more power the longer it takes you to get to your destination, so reducing your speed from 30 to 15 MPH might not be an efficiency win.

- beerandt 5y agoNo- those losses (less the engine idle speed) are relatively larger for electric, because alternator loss is already baked into the efficiency for ice engines.
- hhhhhdsgs 5y agoits the opposite for EVs. Their range decreases as their speed increases due to the increased effect of wind resistance
- elil17 5y agoI believe due to motor efficiency and losses from AC, media system, etc., the most efficient speed for most EVs and hybrids is around 25 mph. I’ve heard 10 and 35 suggested as well.
- beerandt 5y agoNo- electric motors generally perform better at lower speeds, gas at higher speeds. Especially so in direct comparison. Which is why hybrids often switch from electric to gas past some determined speed.
- sudosysgen 5y agoThat's only true because the electric motors don't have a gearbox but the gas engines do.
