Snowmobiles

Ski-Doo pioneered E-TEC direct injection 2-stroke technology in its Evinrude outboard engines, where it won the Clean Air Technology Excellence Award from the US Environmental Protection Agency. This E-TEC system, developed specifically for snowmobiles, delivers several benefits:
Fuel Economy - At 21 mpg US/25 mpg CDN, the 600 H.O. E-TEC uses 15% less fuel than the current Rotax 600 H.O. semi-direct injection (SDI) engine, 78% less fuel than the 600 CFI and 92% less than the Arctic Cat 600 EFI according to Ski-Doo.
Oil Economy - Most owners will have to add oil just once per season because of the added precision of the system's electronic oil pump and sophisticated computer mapping. The 600 H.O. E-TEC uses half the oil of the SDI and 600 CFI, and just a third the oil (66% less) of the Arctic Cat 600 EFI.
Emissions/smoke and smell - The 600 H.O. E-TEC is the cleanest 2-stroke snowmobile engine by a wide margin, meaning there's virtually no smoke or smell.
Lightweight - Because of its 2-stroke configuration, the 600 H.O. E-TEC is naturally lightweight for better handling and reducing rider fatigue. The MX Z TNT with 600 H.O. E-TEC model weighs just 415 lbs. (188 kg).
Hassle- free ownership experience - Engines with E-TEC technology start on the first pull every time; run with a super smooth idle and instant response; the platinum-tipped spark plugs are warranted for 3 years; and feature the industry's first automatic summerization function.
600 H.O. E-TEC owners will save real money over the course of a season. And the instant throttle response and near elimination of smoke and smell will make this engine a pleasure to own and ride for sure.
