An area of effect power-up that causes cars in proximity to have sputtering engine power and lose some of their steering ability for a short time.
EMP was one of the Pick-Ups in GRIP. It triggered a very large area of effect disabling EMP blast which affected racers further ahead more severely, intended to compress the pack. However, its limited range meant that it often failed to catch leaders and its disabling nature made its impact very inconsistent so it was removed. It has been replaced by the Disruptor.
