WHAT’S NEW FOR 2016?
Polaris de-stroked the 999cc ProStar
RZR XP 1000 engine by 5.5mm (from
73.5mm to 68mm), and the forged
93mm pistons have 9.0:1 compression
to live with the new integrated
turbocharger and a 45-percent
increase in torque. It also has high-strength connecting rods, an updated
270-degree firing-order crankshaft,
closed-deck cylinders, sodium-filled
exhaust valves and a new oil system.
The 925cc twin drops from
the XP1K’s compression of
11.1:1 down to 9.0:1 on the
XP Turbo, and it uses the
same 48mm EFI throttle bodies
as the 1000. The inter-cooled
Turbo makes 144 horsepower
and 45 percent more torque
than the 1000, but the Can-Am Turbo and aftermarket kits
place the intercooler behind the
cabin. The Polaris setup has
lots of plumbing to watch.
Polaris has two of the top contenders in the extreme-performance UTV wars,
the RZR XP Turbo EPS and the RZR XP 1000 EPS. Our Dune Patrol Show &
Shine build reflects how much more trick the Turbo is under the skin, but is all
that turbo technology and component upgrades worth the extra $4700? We
spent a week of head-to-head testing to find out.
