Rotax 4-TEC V-800

New Choice for Cruising, Utility
Bombardier Recreational Products Inc. (BRP) is introducing not one, but two new high tech Rotax® engines in its 2007 Ski-Doo snowmobiles line: the 2-TEC™ 800R two-stroke and the 4TEC™ V-800 four-stroke. Both engines are fuel efficient and exceed U.S. E.P.A. emissions standards.
The 4-TEC V-800 is targeted towards consumers who place a high value on maximum fuel economy, four-stroke sound and four-stroke longevity – making it a nice choice for cruising and utility applications. It is either standard or an option on the Legend, Expedition, Skandic Super Wide Track and Tundra models.
“At BRP, we are totally committed to providing lightweight, next generation two-stroke engines for almost all snowmobile applications,” said Pierre Arsenault, Vice-president, Snowmobiles, Watercraft, Sport boats and ATVs, BRP. “But there is a group of consumers out there that want a four-stroke engine. The V-800 is a great choice for them.”
The 4-TEC V-800 is the same engine at the heart of the highly acclaimed Can-Am Outlander 800H.O. EFI all-terrain vehicle, adapted for snowmobile operation. It is significantly lighter than the 4-TEC V-1000 previously offered.
To minimize vibration, the cylinders are oriented at an 80-degree angle. Dual-balanced equal-length inlets lead to downdraft throttle bodies. Each cylinder has its own electronically activated fuel injector for an immediate and responsive injection charge, delivering satisfying torque and power throughout the powerband, as well as outstanding fuel economy. The 4-TEC system’s four valves and roller-follower cam also work to boost torque.
The sophisticated electronic fuel injection and engine management system ensures optimum performance in all conditions at all RPM, including easy starting in cold weather or at altitude.
