What is the maximum diving depth of the Rinspeed sQuba?

The maximum diving depth of the Rinspeed sQuba is 10 meters.

Rinspeed developed the sQuba as a functioning concept car, unveiled at the 2008 Geneva Motor Show. Its design began with a Lotus Elise chassis and drew inspiration from the underwater Lotus Esprit in the 1977 James Bond film The Spy Who Loved Me.

Unlike a conventional submarine, the sQuba has an open cockpit. It can flood its interior while occupants breathe through scuba-style regulators. Twin electric propellers provide forward motion underwater, while water jets at the front help with steering and lift. The car travels at about 3 km/h underwater and about 6 km/h on the surface.

The 10-meter figure describes the prototype’s maximum submersion depth, not a routine recreational diving recommendation. A common mix-up is assuming that the sQuba is a production vehicle: it remained a one-off concept, with no established mass-production program.
