Eli5: How come when I’m stopped in a car and I let go of the brakes, it moves forward without touching the accelerator?
In: Engineering
It’s your torque converter. It’s filled with fluid and is between your engine and transmission.
Some cars have a lower idle RPM like my wife’s Buick and won’t move when you let off the brakes. Others have a higher rpm and can get the vehicle significantly fast with the foot off the brakes.
