First Submergible Car

Rinspeed sQuba is the most exciting thing at this year's Geneva Motor Show and is creating many a ripple.

sQuba is the world's first real submersible car that can 'move like a fish underwater'.

It can dive up to 32.8 feet (10 mt) below the surface of the water and can move at a sedate 1.8 miles per hour.

The sQuba has an open cockpit for 'safety reasons' (so that people can get out easily anytime in case of an emergency). The occupants of the car have to breathe compressed air through built-in scuba masks.

sQuba is an electric car that uses rechargeable lithium-ion batteries and 3 electric motors for propulsion. It is a zero-emission car as documented by the rotating license plate in the rear. It produces no exhaust emissions.

The 'sQuba's' filling station is the water reservoir.? It is no surprise that the vehicle features powerful yet energy-saving LED lighting technology.

The first car that could drive underwater was Quandt's Amphibicar, built in 1968. Only 3,878 were produced but many are still being driven on roads.

Then Gibbs Technologies came up with Gibbs Aquada in 2004 which Virgin boss Richard Branson used to break the speed record for crossing the English Channel.

However, the sQuba seems to be the most exciting of them all.

To drive on the roads, 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.'
