The Panther, the latest amphibious vehicle from WaterCar, claims the advantage of multi-terrain capability as the world's fastest amphibious car capable of doing over 80mph (127km/h) on land and 44 mph (70km/h) on water.
Panther's engine is the latest generation Acura 3.7 liter VTEC V-6, equipped with single overhead camshaft cylinder and 24 valves. The vehicle can move from land to water at speeds of up to 15 mph (24 km/h). During the transition, the driver shifts the four-speed to neutral, and once the vehicle slides into water, she switches to jet drive and lifts the wheels out of the water, hydraulically, all within 15 seconds.
The vehicle is equipped with a chassis made out of lightweight chromoly steel that fits into a fiberglass haul. Lightweight chromoly steel enhances floatability. According to Brian Dodson, writing in Gizmag, chromoly steel has superior properties of "weldability, formability, strength, ductility and toughness" compared to regular carbon steel.
The Panther in impressively stable in water for a vehicle its length (15 feet) and can maintain an even keel on water when stationery.
