Underwater Sport Car

Rinspeed boss Frank M. Rinderknecht (52) is known for his extraordinary automotive creations. The acknowledged James Bond enthusiast and Swiss automobile visionary kept revisiting this scene in his mind over and over: "For three decades I have tried to imagine how it might be possible to build a car that can fly under water. Now we have made this dream come true."

And it is this submerged stabile flight at a depth of 10 meters that sets the "sQuba" apart from military vehicles. While the latter can go under water, they are limited to driving slowly over the submerged ground. Rinderknecht: "It is undoubtedly not an easy task to make a car watertight and pressure resistant enough to be maneuverable under water. The real challenge however was to create a submersible car that moves like a fish in water."

It also had to be a sports car that was converted into a diving dream in the facilities of Swiss engineering specialist Esoro. In a first step the combustion engine was removed and replaced by several electric motors. Three motors are located in the rear. One provides propulsion on land, the other two drive the screws for underwater motoring. They are supported by two powerful Seabob jet drives in the front, which 'breathe' through special rotating louvers from HS Genion (for opening and closing the water intake). The rotating outlet jets were designed to be extremely light yet twist resistant by using hightech nano materials, socalled Carbon Nano Tubes.

It is a sure bet that the "sQuba" will steal the show from any 'Baywatch' beauty on the beach. And easily, too: You drive the car into the water and the car floats. That is, until you crack the door to let the water in. Immediately the "sQuba" starts on his way to the underwater world. The occupants' breathing air comes from an integrated tank of compressed air that divers know from scuba diving. Rinderknecht: "For safety reasons we have built the vehicle as an open car so that the occupants can get out quickly in an emergency. With an enclosed cabin opening the door might be impossible." But safety wasn't the only reason for choosing an opentop design: With an enclosed volume of just two cubic meters of air the vehicle weight would have to increase by two tons (!) to counteract the unwanted buoyancy, giving the "sQuba" the land mobility of a turtle. Without occupants the "sQuba" surfaces automatically.

It is even capable of autonomous driving on land thanks to a sophisticated laser sensor system from the Hamburg company Ibeo without any help from the driver or passenger.
