A brand new engine for Ski-Doo: The Rotax 600R E-TEC

BRP presents the brand new Rotax 600 E-TEC. Inspired by its big brother, the 850 E-TEC, this new engine has technologies that made it the new standard of performance in the 600cc category.

Ski-Doo’s and Rotax engineers had to create a new 600cc engine narrower so it can fit on the REV Gen4 platform. The 850 E-TEC conception criteria were used so the engine can increase power, deliver exceptional dynamic response and reliability and maintain the best-in-class E-TEC reputation in efficiency and durability established by its predecessor. The engine offers 125 horsepower, 5 more than its predecessor and that with only an extra 5cc. We are sure that it will be really popular with the advanced ergonomics of the REV Gen4 platform and the brand new 600cc engine that has the industry’s most advanced E-TEC technologies.

Let’s learn more about the engine with some technical specifications.

Power – The new 600R E-TEC produces a class-best 125 horsepower (+5 over the 600 H.O. E-TEC)

• 599.4 cc – bore 72.3mm x Stroke 73 mm

• Additional 5cc over previous 600cc-class engine

• Mono-block cylinder design – maximum transfer port efficiency

• eRAVE with 3-position electronically controlled exhaust valve ( as per 850 E-TEC) • Shorter intake tract (as per 850 E-TEC) – 35% closer

• Double reed valves (as per 850 E-TEC)

Responsiveness – Creating that same instant throttle response of the 850 E-TEC was a primary goal with the 600R E-TEC for BRP engineering. Using some of the same technologies from the 850 E-TEC, this engine delivers instant acceleration one throttle squeeze after another.

• Second Generation E-TEC fuel injection (same as 850 E-TEC)

• Lightweight, low inertia cranktrain including pDrive and magneto

• Ring gear incorporated into flywheel

• More precise cylinder head voice-coil injectors

• eRAVE that reacts three times faster

• Redesigned exhaust for improved airflow

Efficiency/Durability – Maintaining class-leading efficiency and durability was a primary concern in the 600R E-TEC development.

• Plasma-coated cylinders (as per 850 E-TEC) – reduced friction, holds oil better

• Optimized balancing of the cranktrain components

• pDrive primary

• Robust, powerful magneto is slimmer and lighter

• ECM (as per 850 E-TEC) twice as fast as previous version to manage engine efficiently

• eRAVE delivers better control and efficiency

• Integrated Electric Start

• Intake system improvements with REV Gen4
