Does Upshifting increase or decrease RPM?

667 views

I’ve seen websites that say “Lower Gears in Cars means more power”, Which is what I’m guessing, means more rpm, but then I see other people say that if you increase the gear, then it makes the rpm higher… Which one is it?

You’re mixing two different things.

Gears regarding power or speed refer to the drivetrain aka the rear end or simply the axle, the bar which turns the tires.

Upshifting refers to changing gears at the transmission aka gear box (different from gears in the axle)

Upshift just changes which gears your using in the gear box.

So the engine increases rpm and using a different gear allows for the engine to turn the wheels faster.

Upshifting doesn’t create more time it allows for more rpm.
