Marion Hyper-Sub, the $3.5M Submersible Powerboat

autoevolution likes, from time to time, to rub your noses in it, sort of speak, and give you a little preview of things you will NEVER own. Aside from the over-discussed super-mega-extra-luxury cars, we found our readers to have quite a soft spot for yachts, powerboats, spacecrafts and such. After we gave you a little taste of the $137 million WHY Yacht and the $200,000/flight VSS Enterprise, it's time to have a look at yet another out-of-this world non-automotive cake.

Enter the Marion Hyper-Sub, a $3.5 million personal underwater powerboat. Deployable from any given superyacht, the Hyper-Sub is, according to Luxist, the first small craft capable of operating, autonomously, in the open sea.

Marion's HSPD Hyper-Submersible Powerboat Design is powered by two diesel engines, each outputting 440 horsepower. They give the powerboat-sub a top speed of 40 knots. It can travel 500 miles above sea level, and can dive to a depth of up to 250 feet (76 meters) with a safety factor of 17.

The Hyper-Sub comes complete with GPS, chart plotting, radar, forward and downward sensing sonar and even an autopilot. For the comfort of the 5 occupants, the Hyper-Sub comes complete with woodgrain interior and plush leather seating and is, according to its creator, "customizable to fit your unique taste and desire."

Marion plans not one, not even two, but three versions of the Hyper-Sub. The one we described above is called HS-250 Sport and is meant for individual owners and charter operators. The HS-600, less pretentious, is built for industrial, salvage, or government operations, while the HS-1200 is the new toy for oil and gas operations, scientific research and salvage.

The Hyper-Sub is still in prototype stage, but Marion plans to debut production soon.
