Is there a scenario where a layman would use it (i.e. evasive maneuvers)? In what scenario would a racer use it?
Edit: Yes, I mean accel+brake. Heel-toe, etc
In: Engineering
Power braking is a method for launching a car with an automatic transmission by holding the brakes and increasing engine rpm. It has basically nothing to do with braking a car in motion. It is probably most commonly used to initiate a burnout in RWD automatic cars.
It’s not great for your car as it builds heat in the torque converter of the transmission. It can also be hard on your brakes.
Race cars with automatic transmissions are unlikely to use power braking, since they rarely use torque-converter automatics. Some of them may also have launch control features.
