I haven't seen the internal layout yet, but I imagine that it uses the stock GM 2.4L and front wheel drive 6 speed. It would be very easy to just lock the left side output and use just the right side axle output for the front drive sprocket. If this is the case, there would be no separate 90 degree gearbox, just a belt sprocket on a axial reinforced right side output from the transaxle .
That's what I like about you Dan, you have an opinion on everything, whether it's informed or not......

From the Polaris web site it shows the drivetrain to be a longitudinal mounted inline four mounted to a standard 5 speed rear wheel drive transmission, drive shaft, 90* bevel box then to a final belt drive.
Very similar to the 3W (other than the engine)
