Minneapolis, March 5, 2015- Polaris Industries Inc. (NYSE: PII), the leading manufacturer of off-road vehicles (ORVs), today announced a partnership with the Grand National Cross Country Series (GNCC) to sponsor GNCC’s newly-added Single Seat Class. In January 2014, Polaris introduced the revolutionary 32 horsepower, single-seat Polaris ACE which was designed to combine the size and nimble handling of a Sportsman All-Terrain Vehicle (ATV) with the confidence and comfort of RANGER and RZR side-by-sides. The vehicle generated so much interest that six months later, the company introduced a second model with a 45 horsepower ProStar™ 570 engine. The ACE architecture appealed to a wide-variety of riders, including racers, which was demonstrated last fall when GNCC and Polaris offered an exhibition ACE Editor’s Race at the Ironman, in Crawfordsville, Indiana.“GNCC is excited to introduce the Single Seat Class into our racing format,” said GNCC Director Tim Cotter. “When Polaris commits to something, they commit 100 percent and we have no doubt that the ACE is destined to be a main stay in off-road.”The GNCC Single Seat Class will be available for single seat production models up to 570ccs, and engine and suspension modifications will be permitted. The vehicles will race on the UTV course but in a separate race from the UTVs.
