Default Why does the car accelerate itself?

Let say I'm driving and I press the gas about half way, the RPM would just go from 2 -4 in an instant, like it gets mad, like you can hear it. Like the RPM is suppose to gradually go from 2-4, not in an instant, and the car would take forever to reach 60mph like it doesn't go any faster. I'm confused someone please help me.

Is it an Auto or manual? How many miles? Sounds like the clutch might be slipping.

It sounds like you have a slow car with an automatic transmission. The behavior you noticed is probably a downshift, totally normal.

If the car is manual, TrickNipple's suggestion is probably correct.

How many miles? I would guess it is a slipping clutch.

It's not an unreasonable lifespan for a clutch.

Get it out on the highway in top gear and punch the gas pedal.

If the tach spikes and drops back down when you let off, the clutch is likely gone.

Any update on this?

Do you really need to go on a highway? Couldn't you just get going at say like 35-40 and put the car in 5th, put your foot down and be able to figure that out then as well? The car should slowly gain speed but if you see spikes in rpm, the clutch is probably the issue.
