Den Polaris RZR (pronounced “razor”) is a sport side-by-side produced by Polaris Industries. When launched in 2007 as a 2008 model, it was officially known as the Ranger RZR, as it was marketed as a sub-model of the larger, work-oriented Ranger. As the RZR gained popularity, Polaris eventually dropped the Ranger designation and positioned the RZR as a stand-alone model.
U.S. Special Operations Command, (US)SOCOM, placed an order with Polaris Defense in September 2013 for up to 1,500 MRZR-2 (2-seat) and MRZR-4 (4-seat) machines. A big drawback of these new small military vehicles, was that they retained their original petrol engines, which are incompatible with standard military JP-8 fuel. In terms of logistics, two different fuel types are clearly not ideal. As few such machines see combat use, and civilian users are uninterested in running them on diesel, an engine change was deemed unlikely.
