Just before we went to the printer with this issue, Ski-Doo sent out a notice revising some previous figures on fuel and oil consumption on its E-Tec 800R engine.
Ski-Doo states that after "extensive testing, specific to how the vehicles will be used, we have revised the fuel and oil consumption rates for 2011 Ski-Doo snowmobiles with the Rotax E-Tec 800R engine."
The company noted that the E-Tec version of the 800R produces "noticeably more power" than the PowerT.E.K. version. Third party testing at Dynotech Research last spring showed the E-Tec 800R generating 163.9 hp.
As for the fuel economy on the E-Tec 800R, based on internal BRP testing, the trail version of the sleds with that engine-MX Z and Renegade-should get up to 19 mpg, which is about 14 percent better in fuel use versus the 800R PowerT.E.K. Oil consumption is up to 30 percent less at 176 miles/qt.
As for the E-Tec 800R in Summit configuration, due to its specific use, it will get up to 12 percent better fuel economy while the oil consumption remains about the same, versus the 800R PowerT.E.K.
