I just did some digging and was surprised to learn that the can am x3 rs turbo rr is listed as 1877 lbs. That's DRY weight. How much do the fluids add? 40lbs? 50 lbs?
Assuming 50 lbs, the rs turbo rr weighs about 1,927 lbs. If I recall previous discussions of the Speed weight vs others, the El Diablo was guesstimated at 1,950 lbs, wet. That's only 23 lbs more. With 25 more hp on 91 and 100 hp more on E85, should be considerably quicker and faster than the competition, unless the CVT is somehow losing a lot more power than other CVTs, which is pretty unlikely.
Then there's the cruising gear... sequential, shift under power, of course.
