Fenergy Zap

Fenergy Zap is a power-up in MySims Racing. Use it to zap the opponents in front of you full of Fenergy, which in turn overloads their engines and slows them down and prevents them from boosting! Small gears, indicating the car being malfunctioned, will spout out of their cars as well. Speed ahead of them while you can.

Official Description
This sends out a burst of F-Energy, overloading the engines of opponents ahead of you to temporarily reduce their speed and prevent them from boosting.
