Gibbs Quadski

[1] The Quadski uses a marine jet propulsion system as well as wheel retraction, allowing it to transition between land and water.

The Quadski, developed and manufactured by a team based in Detroit, shares several features with the Gibbs Aquada.

[2] To switch to water mode, the driver presses a button that retracts the wheels into the vehicle's body and disconnects them from the drive train.

Official Quadski parts and technical support are supplied by Gibbs Amphibians in New Zealand.

[5] A Quadski was used in a 2014 episode of British motoring show Top Gear, when Jeremy Clarkson raced it across Lake Como against an Alfa Romeo 4C driven by co-host Richard Hammond.
