P
olaris raised the stakes
on UTV power by
releasing its 2016 model
RZR XP Turbo EPS. With
144 horsepower, it's the
most powerful engine in a side-

It features all new clutches and
drive belt, along with a beefed-up
transmission with geared reverse and

all-wheel drive system. Polaris
also added a clutch air cooling
system that reduces clutch and belt
temperatures to extend the belt life.
The new Polaris ProStarĀ® Turbo
engine, utilizes a turbocharger,
giving it the industry leading power
that allows the RZR XP to accelerate

connecting rods, a closed deck

with front-mounted radiator
and high-flow electric pump. An
