This Vehicle Claims It's the World's Fastest Amphibious Sports Car -- See It in Action!

We've brought you the largest and speediest land-to-sea vehicle for its size and the concept of Volkswagen's "Aqua Car," but here's a prototype that combines both speed and sporty design. The Sea Lion by Marc Witt recently set what is believed to be a world record for amphibious vehicles.

The car, which is being sold at the moment for $259,500, travels up to 125 mph on land and 60 mph at sea. According to Fantasy Junction, the site hosting the car listing, YouTube is currently an "internationally accepted" source for speed documentation. Check out the car's specs and see it go from land to sea in this video:

The website says that the car beat out 25 other contenders in an unofficial competition for top speed in the amphibious category. It also says they don't necessarily want to make it a more official competition as the "participants enjoy the freedom of having a complete lack of rules."

The Sea Lion, a project that started in 2006, is constructed with an "integrated monocoque welded uni-body center section" and has removable side pods for floatation and cargo. It's current engine is a Mazda Rotary 13b, which Witt states in the listing is what limits the car from going even faster in the water. A higher horsepower engine would amp up its performance at sea. Witt suggests it be upgraded to a Renesis Rx8 unit.

Witt even offers to help the buyer of the vehicle with any future modifications of the car, should they want his insight.

"I will remain available as a consultant, engineer, machinist and psychiatrist for whoever decides to venture further into the amphibious record books," he said.
