Hover mode is a special driving mode available exclusively to the Jansen P12 88 Special and the Jansen Toy 88 Special. Clicking activates 'Hover Mode' which retracts the wheels into the car and pushes the 88 Special off the ground. This special mode of travel does not allow the vehicle to vertically takedown other opponents.
Applying the e-brake to a vehicle in hover mode has little or no affect to its handling although the brakes of the vehicle have been tweaked to give superior handling. Using the brakes in Hover Mode is almost more effective than using the e-brake in normal Road Mode.
