Mark I Edit
The Mark I was powered by 2 90-horsepower BMW motorcycle engines(alongside the original Ford Engine), producing 180 horsepower. A fan was fitted in the back for a thrust, and a small grass skirt made by James May was fitted below. However, their initial design failed because Jeremy took it very fast into the River, thus sinking the Hovervan. Jeremy blamed Richard's 90 horsepower engines, while James and Richard blamed Jeremy.
After the failure of their Mark I design the presenters had a rethink and came up with a new and improved design. Richard changed the engines powering the hovervan (now it's sourced from a Radical track day car) meaning that their creation was now being powered by 600 horsepower engine . James also added much bigger and tougher skirts and tubes which would prevent the vehicle from sinking. To test this new creation the presenters headed to the River Avon. After an initial another unsuccesful test with their creation, leading to the cracking of the windscreen of the van, the presenters recieved a challenge; they were to travel to a nearby flood-affected town in their Mark II Hovervan.
There were a lot of problems, the fan beneath was causing a heavy shoverm annoying the people. They rammed a boat, and the man using it fell into the river. The presenters also complained about the heavy noise, both inside and outside. They also get trapped in a canal change, and Jeremy takes a wrong turn and takes it down a weir and burns out and stales the engine whilst trying to go back up it.
