It's been in production for a long time, and now the Quadski is finally getting a commercial release. Gibbs's amphibious Quadski ATV tops out at 45 mph on both land and water, and can go from a land-based vehicle to a boat with the push of a button. Official pricing will be announced closer to the Quadski's on-sale date, sometime in mid-November, although the price tag will probably be around $40,000.
While a description is nice and all, to get a real feel for how awesome the Quadski is, you need to see it in action. Click the link for a video.
