Do elec­tric cars have gears?

How It Works - - BRAIN DUMP - Mandy Hicks

Petrol en­gines only work well when run­ning at par­tic­u­lar speeds and pro­duce very lit­tle force (torque) when they are run­ning slowly. This means petrol cars wouldn’t work prop­erly without gears to man­age the power out­put of their en­gines, but elec­tric mo­tors don’t have these prob­lems. They work ef­fi­ciently run­ning fast or slow and pro­duce a lot of torque even when run­ning at only a few rev­o­lu­tions per minute. So elec­tric cars only need one gear.

Be­cause elec­tric car mo­tors only need a sin­gle gear, elec­tric cars can be made lighter
