Rinspeed sQuba Concept

From Rinspeed press: 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 high-tech nano materials, so-called 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 wasnt the only reason for choosing an open-top 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.

Power is supplied by rechargeable Lithium-Ion batteries. Rinderknecht: The sQuba is a zero-emission car as documented by the rotating license plate in the rear. It produces no exhaust emissions. The Swiss are among the worlds pioneers in the area of hydropower. The sQubas filling station is the water reservoir. It is no surprise that the vehicle features powerful yet energy-saving LED lighting technology.

3-D foil elements with embossed fish and sharkskin patterns from Wetzel Processing Group and Hornschuch add visual pizzazz and streamline the exterior. Together with styling elements from Foliatec they create a harmonious velvety matt-white appearance. 

For shore leave the sQuba relies on a stainless coil-over suspension from KW automotive and large Pirelli tires mounted on custom-made forged light-weight wheels from AEZ with 17- and 18-inch diameters. But the sQuba is really at home in the water. To make the occupants feel at home there as well the innovative salt-water resistant interior from Strhle + Hess features genuine mother-of-pearl trim and diamond-plated non-slip inlays from KGS Diamond, normally used in high-tech abrasives. After all, diamonds are a girls best friends. The high-tech VDO instrument cluster and controls create a futuristic ambiance and allow controlling all vehicle functions even while submerged.

Frank M. Rinderknecht and his partners - amongst them also the fleet specialist LeasePlan - have created a truly unusual vehicle and in the process have thought of everything. Even the Motorex lubricants used in the sQuba are biodegradable. For the Rinspeed boss that is a meticulousness stemming from conviction: The sQuba lets me be one with the elements and lets me immerse myself in a new and fascinating world - with Q factor. It is our duty to protect this world in which we are guests to the best of our ability. Isnt it, Miss Moneypenny? - James couldnt have said it better himself glancing at the sporty Swiss precision chronograph from C.F. Bucherer. Eau la la - shaken, not stirred.
