Some of the rigs we profile on this blog teeter on the edge of what an ATV really is. Take for example, the Amatoya ATV from designer Liam Ferguson of Monash University. Purely in concept form right now, this 2-passenger quad might be a new way to suppress fires. It features a high-visibility cockpit and can unload 500 gallons of water from the Remotely Operated Suppression Cannon Outfit (ROSCO).

While ATVS go by many names–quad, quad bike, three- or four-wheeler–the American National Standards Institute defines it as a vehicle that travels on low-pressure tires, with a seat that is straddled by the operator, along with handlebars for steering control. ATVs, by this definition, are intended for use by a single operator.

So is the Amatoya an ATV, UTV or something entirely different?
