World's first high speed amphibious vehicle

The world's first high speed amphibious vehicle will go on sale next month, according to its creators.

The vehicle - called the Quadski - can travel at speeds of up to 45mph on water or land.

To go in the water, the driver presses a button and its wheels retract in five seconds flat.

The vehicle will go on sale in the US next month and is expected to cost around £25,000.

Alan Gibbs, founder of Michigan-based Gibbs Sports Amphibians, says they have spent 16 years and £125 million on the project.

"Although initially the Quadski will only be for sale in America, we expect to find a ready market for it across the world in 2014," he said.
