yes it makes your car go really slow
I think it's to do with friction and the material you have on your ramp.
When toy cars go down a steep hill they pick up momentum. Which makes them go faster so a car on a steeper hill will go faster then one on a flat surface.
check oil level. go to engine shop.
get a steeper hill
To make the car go or slow down.
as little as 0 mph
Dirty air filter? Dirty fuel filter? Plugged catalytic converter? number 1... it's not a car... number 2... try giving it a little gas when you go up the hill
it depends on how steep the slope is.
pretty sure its friction
you go onto first gear
It will go slower up hill and faster down hill.
