The sQuba
Eco friendly seems to be the automobile industry’s new moto. As environment awareness is growing into the mainstream, more and more car companies are developing green cars which have excellent designs and performance. The sQuba is the world’s foremost car that can be driven on land as well as under water. It is developed by Swiss company Rinspeed. The sQuba is a zero emission, all-electric vehicle which uses 3 electric-motors, one for land and two for water. On land, it is powered by its electric, rear-wheel drive power-train to speed of 80mph, using rechargeable lithium-ion batteries. Upon entering water, it is powered by twin electric-powered propellers with two Seabob water jets and can be submerged to a depth of 10 meters. On the water surface, the speed is 3.7 mph and underwater it is 1.9 mph. It is almost out of your budget but is a real Bond car.
