Incredible Amphibious Cars
This aluminum bodied, meticulously crafted amphibian is unique in that it literally transforms its shape fromLAND MODE toWATER MODE with the flip of a switch. On land, its full length articulating sponsons are raised and become the car s fenders. Upon entering the water, the sponsons are lowered nearly eight inches to transform the car into a tunnel hulled watercraft within a matter of seconds. It s main body is made of type 304 stainless steel, so rust will not be a problem. Under the hood, it has a fully dyno tuned Chevrolet engine that produces 762 horsepower at 5,800 rpm. Originally, the car used a six bladed propeller. However, according to Dobbertin, this didn t create enough bite in the water, so he replaced it with a four bladed Rolla stainless steel propeller that was yet to be tested in the water before the HydroCar was sold. Despite required tweaking, it s still an incredible amphibious vehicle.
