Rinspeed sQuba
Okay, so late last night we covered the early Lotus Esprits and their fictional white submersible doppelganger. The submarine Esprit in the James Bond film The Spy Who Loved Me was obviously fictional--a creation of late 1970s special effects. But what if an actual vehicle could be made to convert seamlessly from car to submarine?
Swiss tuning company Rinspeed, inspired by Bond's Esprit, tackled this intriguing challenge and displayed its sQuba concept car earlier this year. It's a fascinating vehicle, but a close look at the finished project reveals just how difficult it is to create a vehicle adept both on pavement and underwater.
Naturally, Rinspeed started with a white Lotus--in this case, the Elise. The Elise's gasoline engine was replaced with three electric motors and a lithium-ion battery pack. On dry ground, a 54-kilowatt electric motor drives the car, while while two smaller electric motors power small propellers underwater. Two front fender-mounted blow jets pivot to provide directional control. Other technological pieces of gingerbread include an onboard air supply, a salt-water-resistant interior, and a laser sensor to allow driver-less operation (think KITT of Knight Rider fame).
