I have been unable to locate a dealer with an EV in stock, so my evaluation has been limited to what I can find on line and in the Owner's Manual, which I downloaded from the Polaris web site. I don't like their AWD/differential lock setup, which seems to be common to all their machines, one bit. From reading the manual and talking to a dealer, it is not possible to operate in 4WD without a locked rear differential. Nor is it possible to descend a hill with the 4WD engaged. Add that to the fact that wheel spin has to occur before 4WD drive engages and it makes the entire line unacceptable to me.
These are my drive train requirements.
Manually selectable four wheel drive
Lockable open rear differential, lock independently selectable
At least two ranges
After looking at how the various makes handle 4WD, differentials, and differential locks, I determined that Kubota, Kawasaki, Kioti, and Cub Cadet have acceptable arrangements. Yamaha, Honda, Club Car (including their rebadged alter egos), Polaris, Arctic Cat, and Can-Am don't. I am not sure if JD does or not. I do know that JD diesels are way out of my budget and the gassers are much too thirsty, so I haven't looked beyond that.
Other factors eliminate most models from my list of acceptable drive arrangement brands, leaving me with a small group of models to select from.
