       A CAR design team is bringing back memories of a famous scene from a James Bond movie by producing a car that can travel under water．

       In the 007 film, The Spy Who Loved- Me （1977）, Bond drives below the waves in a vehicle that moments earlier seemed to be an ordinary car．

       The scene was shot using special movie magic, but more than 30 years later the Swiss company Rinspeed has come up with a concept （概念） car - the sOuba．It is an open-topped sports car that car drive over land, above the waves and even under water to a depth of 10 meters．It is to be displayed at next month's Geneva Motor Show．

       Rinspeed boss Frank Rinderknecht, 52, is a James Bond fan．"For three decades I have tried to imagine how it might be possible to build a car that can fly under water," he said．"Now we have made this dream come true．”

       To make sQuba, Rinspeed took a sports car and replaced the ordinary engine with several electric motors．Three motors arc located in the back of the car．One provides power on land while the other two drive the screws （螺旋桨） underwater．

       For safety reasons sQuba was built as an open car so that people can get out quickly in an emergency．With an enclosed cabin （封闭车厢） opening the door might be impossible because of water pressure．

       sQuba is easy to drive．When you go into the water it floats, until you open the door to let the water in．Soon the sQuba starts on its way to the underwater world．To breathe, you'll have to wear a scuba mask（潜水面罩） connected to the car's compressed-air （压缩空气） tank．The vehicle can stay under water until you run out of air, which is about two hours．

       Sadly, those people excited by the sQuba may never be able to drive one as there are no plans to put it into production．

       "It's a tradition that we produce a concept car for the Geneva Motor Show．"said Rinderknecht．"We don't plan to build it," he admitted．
