                        The sQuba concept from Rinspeed is a zero-emmission sports 
                        car which has the ability to dive underwater up to 10m 
                        (33ft) deep. 
                         
                        The sQuba is based on a Lotus Elise chassis, however in 
                        order to operate on both land and underwater the engine 
                        has been removed and replaced with three electric motors 
                        supplied with power by rechargeable Lithium-Ion batteries. 
                        One of the motors is used to provide power on land, while 
                        the other two drive the screws at the rear of the concept 
                        once underwater. Also helping to propel the sQuba underwater 
                        are two rotating jet drives mounted up front. 
                         
                        To get underwater the driver takes the sQuba onto the 
                        water and simply opens the door slightly to allow the 
                        water to flood in. The sQuba can then be controlled underwater 
                        using the rear propellors and front water jets. Onboard 
                        breathing apparatus for the driver and passenger is mounted 
                        behind the seats. 
                         
                        Part of the reason for not choosing a hardtop vehicle 
                        is for safety - with an open top car the occupants can 
                        quickly swim to safety in an emergency. The other reason 
                        is because of weight. If the sQuba was airtight the extra 
                        weight needed to submerge the vehicle would be around 
                        two tons. Seriously crippling performance, and aesthetics, 
                        both on land and underwater. 
                         
                        Diving underwater is not the only trick up the sQuba's 
                        sleeve. The concept is also capable of driving on land 
                        autonomously thanks to laser technology developed by Ibeo. 
                        "The Rinspeed Concept Car is an impressive example 
                        of whats possible today in the area of active driver 
                        support using our laser scanners". Said Ibeo managing 
                        Director Dr. Ulrich Lages. "Our laser sensors permit 
                        a variety of driver assistance functions using one single 
                        small device, e.g. automatic emergency braking, pedestrian 
                        protection, collision protection, traffic jam assistant 
                        and others."
