Polaris’ New Four-Strokes Yellowstone-Approved

Two model year 2006 Polaris snowmobiles with the Polaris FS four-stroke engine have been recognized by the U.S. Department of Interior as having Best Available Technology (BAT), so they are certified for use this winter in Yellowstone National Park.
Snowmobile use in National Parks such as Yellowstone has been closely monitored and subject to stringent operating regulations in recent winters. With their BAT certification, both the 2006 Polaris FS IQ Touring and FS Classic may be ridden on the scenic snowmobile routes throughout Yellowstone National Park this winter.
The FS engine used in both models is a smooth, quiet and fuel-efficient four-stroke engine with a sophisticated engine management system. This liquid-cooled, two-cylinder engine with four valves per cylinder already exceeds EPA emission standards set for the year 2012.
“We are proud to have earned BAT certification for our newest generation of efficient four-stroke engines,” said Polaris Snowmobiles General Manager Eric Lindquist. “This marks the fifth consecutive model year in which Polaris four-stroke technology has earned BAT certification, and we continue our commitment to developing four-stroke technology that meets Polaris riders’ performance standards and is environmentally friendly.”
Earlier Polaris snowmobiles that were certified and continue to meet BAT requirements include the Frontier Touring of model years 2002 through 2005 and the Frontier Classic of 2003 and 2004.
The BAT-compliant 2006 Polaris FS IQ Touring and FS Classic are powered by the FS engine.
The engine management system regulates the fuel-air mixture at every throttle setting and it adjusts for elevation or temperature changes. The FS IQ Touring is built on the Polaris IQ Touring Chassis, which includes features such as Rider Select ergonomics package. The FS Classic is built on the IQ Chassis, and like the FS IQ Touring, it has Rider Select.
