It sounds more like a record-breaking sandwich than personal underwater transportation. The new Super Sub provides untrammeled views of the ocean while slicing through the water like a porpoise in heat. The private submarine is the world’s most hydrodynamic mini-sub thanks to its long body and round cockpit. The electric-powered Super Sub generates 80 horsepower from its four thrusters and lithium-ion batteries, and the built-in hydrofoils provide excellent underwater manueverability. It can dive to a depth of 1,000 feet, as well. The interior boasts luxury car-level treatment for two, and helming it requires the use of two joystick controls. Deliveries start in 2023. Cue Aquaman now.
