Snowmobiling will continue to offer a unique form of recreation to mankind. A recent study conducted by the Recreation Roundtable showed that people who recreate outdoors are happier, healthier and more productive. They are better citizens and neighbors. As our future holds new demands on our time, the recreation that snowmobiling affords will increase in importance.
The future will see the snowmobile itself continue to improve in dependability, reliability and quality for all consumers. Manufacturers, using the latest in technology and science, are working and investing in order that all aspects of the machine are updated to serve the needs of a growing populace.

HISTORY OF MANUFACTURERS TECHNOLOGY IMPROVEMENTS
The EPA now regulates snowmobile engine emission levels. New Technology EPA certified snowmobiles are offered for sale in the model year 2006 and have been on the market for 4 years.
2006 - National Emissions Regulation for snowmobiles, promulgated by the EPA begins.
2003 - The four snowmobile manufacturers all introduced for sale clean, 4-stroke, high technology machines. In addition to 4-stroke technology, semi-direct injection 2-stroke technology was introduced into the marketplace.
2002 - First commercially available Four-Stroke snowmobiles were introduced.
2002 - All new snowmobile exhaust systems were identified with the SSCC label signifying they were tested and certified following strict SAE Compliance procedures
1998 - Developed Frequency-Tuned intake system resulting in reduced engine sound level.
1995 - Promotion of oxygenated fuel, and technology improvements to allow use of oxy-fuel resulting in emissions reduction of 19% and 31%.
1994 - Altitude compensating carburetors introduced resulting in emissions lowered as a benefit of more accurate fuel and air metering.
1991 - Electronic Fuel Injection introduced resulting in emissions lowered utilizing electronically controlled air and fuel metering.
1988 - Movable Exhaust valves introduced resulting in largest single improvement for sound reduction and emissions lowering both.
1977 - Oil injection introduced resulting in reduced oil consumption and exhaust emissions.
1976 - Secondary air silencer introduced resulting in further reduced air-intake noise.
1976 - Center Dump Pipes introduced resulting in reduced exhaust noise.
1975 - Pipe wrap of exhaust systems introduced resulting in reduced shell noise from expansion chamber.
1975 - Fin dampeners in fan-cooled engines introduced resulting in reduced high frequency sound from cooling fins.
1974 - SSCC Regulations Promulgated resulting in mandated sound reductions and comprehensive SAE regulated testing for all OEM snowmobiles.
1973 - CDI Ignition developed resulting in emission reduction from improved combustion.
1973 - Hood Foam Lining introduced resulting in absorbed under the hood sound.
1973 - Intake air boxes introduced resulting in reduced air intake noise.
1972 - Fully enclosed engine compartment introduced resulting in trapping noise under the hood.
1971 - Variable ignition timing introduced resulting in more efficient combustion, less emission and better fuel economy.
1970 - Aluminum clutch introduced resulting in increased efficiency, lower emissions and better fuel economy.
