When I made the statement below, I guess being the Engineering type I thought that this would be a great feature for an ATV. This would make the ATV more like an SUV (like a Jeep Grand Cherokee's AWD system). For those who just like to throw it in gear and go you use the Automatic selection, for those of us who like to tinker we could use the manual engagement selections. The Auto setting could also be smart enough to handle turning issue that BryceGTX brought up. All of this technology exists it just needs to be implmented on a smaller scale for an ATV. Polaris has a locking diff on the rear axle on a Ranger already. So why not put one in front too.....

I have read the docs on how the Current Hillard system works in ATV, but lets not think narrow mindedly about how things are done now, but think in terms of how they could be......

All you say could be done with sensors and a computer but to me that is just more to mess up.I like the notion of less moving parts and less electric is better.

 

Good point ZMan079. Probably the utimate 4wd system uses open differentials in front, back and in the transfer case and uses ABS brakes to keep the slipping wheels from spinning. This gets around all the problems of steering, but allows full traction to a single wheel. Would be interesting if this could be done without a significant weight penalty. But then as ftwflh points out, it adds electronics and sensors. The interesting thing I see about the current Polaris system is that it is relatively simple, but very effective.
