Update!!!
Well, sort of. I was speaking to a dealer over the phone today, and they had gotten some word that at one time Can Am was considering on using and engine which was based on a snow mobile engine called the elite.
I did some research on the Elite and found that is a Rotax® 4-Tec™ 1500cc 4-2troke engine with three in-line cylinders and top fuel efficiency. If this is the case, this is going to be an animal, and just the vehicle that I have been looking for.
