Known as the Sea Lion, this remarkable brushed aluminum and stainless steel amphibious supercar is capable of land speeds of approximately 180 mph (290 km/h) - ample to break the existing land speed record for an amphibious vehicle of 125 mph (201 km/h).

Despite appearances, the Sea Lion uses a bare minimum of structural parts from other vehicles. Instead, one Mr. M. Witt designed and built the car from scratch in order to break the rather slapdash and anarchic-sounding Amphibious World Speed Record.

With its current spec the Sea Lion is optimized for land speed, and it sounds as if the Sea Lion fares less well in the water, which is ironic considering the mammal for which it is named is at its speediest and most graceful when swimming. Mr. Witt indicates that the water speed is limited to by the Sea Lion's power, and recommends improvements. "The engine should be upgraded to a Renesis RX-8 unit," he suggests. The car is currently powered by a Mazda 13B Rotary engine.

In any event Mr. Witt offers his services to any future owner. "I will remain available as a consultant, engineer, machinist and psychiatrist for whoever decides to venture further into the amphibious record books," he says (emphasis added by Gizmag for cautionary effect).

The Sea Lion has an asking price of US$259,500, and is available from Fantasy Junction. See below for a video of the Sea Lion doing its aquatic thang.
