An amphibious all-terrain vehicle (AATV) is a small off-road, and typically six-wheel drive, amphibious vehicle. They were developed in the early 1960s and quickly became popular in both the US and Canada. These vehicles are now used by enthusiasts and professionals worldwide for recreation and industry. These vehicles earned their own classification - ''all-terrain vehicle'' (''ATV'').〔(ROUTE6x6 and Amphibious All Terrain Vehicles "AATV" )〕 However, after the introduction of small three- and four-wheeled off-road motorcycles in the 1970s and 1980s, these have become better known as ATVs than the original amphibious ones. ==History== (Amphibious) ATVs were made in the United States a decade before 3- and 4-wheeled ATV's were introduced by Honda and other Japanese manufacturers. After the presentation of the Jiger in 1961, numerous manufacturers offered a number of similar small off-road vehicles, that were designed to float and were capable of traversing swamps, ponds and streams as well as dry land. Because they were smaller and much simpler in construction than (amphibious) cars, they were much cheaper to produce and quickly gained considerable popularity. By 1970 there were almost 60 companies producing amphibious 6x6 vehicles. There was even a professional racing association dedicated to the 6x6, holding numerous competitions across the USA. These amphibious vehicles were originally called all-terrain vehicles - or ''ATV''s. In the early 1970s however there was a rapid decline in sales of this type of ATVs, forcing most manufacturers to cease production. Reasons were: * the 1973 oil crisis prompted many North Americans to tighten their belts and spend less on recreational vehicles. * the introduction of the 1970 Honda ATC90 threewheeler offered a fun alternative at some $600 / $800, when a 6x6 would cost $1,500. * The simple construction of the original ATVs attracted many companies that were interested in making a quick buck, but underestimated the engineering needed, leading to poor quality products, that gave the industry a bad reputation. * With most models utilizing 2-stroke engines, the 6x6's didn't run well unless properly maintained. 4-strokes were available, however, they were under-powered with at most 12 hp. Only a small number of manufacturers of this type of vehicle remain today. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Amphibious ATV」の詳細全文を読む スポンサード リンク
