Looks like the 800 Ranger 6x6 just got a new lease on life, at least for the rest of 2015.
After being "dropped" by Polaris at the end of 2014 due to the tightening of emission control standards,
it recently received an EO extension by CARB:
Polaris has added it back into their 2015 model line-up on their website, too.
For reasons known only to environmental bureaucrats, the 6x6 Sportsman 800 Big Boss was not extended.
