Industry Dirt: RZR SP Turbo EPS takes RZR to a new level

Published in the October 2015 Issue April 2016

Polaris raised the bar yet again by launching the all-new 2016 RZR XP Turbo EPS. Razor-sharp performance has officially been turbocharged.

Specifically built to take extreme performance to a new level, the all-new Polaris ProStar Turbo engine with turbocharger provides an industry-leading 144 hp, an impressive acceleration of 0-60 mph/96.6 kph in 5.89 seconds and more than 45 percent more torque. The ProStar Turbo is the most powerful side-by-side engine available from the factory for unequalled power, torque, durability and excitement. The new engine was developed for extreme performance and features an impressive number of high performance parts including forged pistons, an upgraded 270-degree firing order forged crankshaft, high strength connecting rods, a closed deck cylinder, sodium-filled exhaust valves and a new oil lubrication system. For consistent performance at all temperatures, the vehicle also includes a new liquid charge air cooler with front-mounted radiator and high-flow electric pump. To control the massive power delivered by the ProStar Turbo, the engine management system has also been updated to include knock detection, boost control and a high-flow return-style fuel system, ensuring that the engine delivers maximum power under all conditions, altitudes and temperatures. 

To harness all that power and deliver it to the ground, the RZR XP Turbo EPS features a brand-new, fully-engineered and stronger driveline for maximum durability. The ultra-efficient driveline features an all-new, high performance PVT system with all-new clutches and drive belt; a new, stronger transmission with geared reverse and stronger shafts; and a High-Performance, True On-Demand All-Wheel Drive System to distribute the massive 144 hp to the ground. The new, high-flow, targeted clutch air cooling system is designed to reduce clutch and belt temperature to enhance and extend belt life. 

The RZR XP Turbo EPS boasts the most precisely-tuned suspension due to the vehicle’s highly-tuned Fox Podium Internal Bypass Shocks offering the plushest ride and best handling found on a side-by-side. The shocks generate progressive damping force that gives the vehicle a smooth ride with all the bottom-out resistance expected from an ultra-performance off-road vehicle. Large diameter shock bodies (3 in/7.6 cm rear, 2.5 in/6.4 cm front), adjustable remote reservoirs and increased fluid capacity provide dramatic improvements in heat dissipation, fade resistance and durability. The internal bypass technology uses five compression zones to provide progressive damping as the shock gently absorbs bumps and stiffens to prevent bottoming. Combine that with three zones of rebound damping to minimize pitching and harsh top-out to give you an ultra-plush ride and better handling over a wider range of terrain at any speed.

To complement the shocks, Polaris outfitted the RZR XP Turbo EPS with bigger coil-over springs. The progressive rate upper spring is a lighter-weight spring that absorbs small impacts while the stiffer main spring maintains ground clearance and absorbs bigger impacts in rough terrain. The suspension setup ensures the RZR XP Turbo EPS can tackle the toughest terrain while keeping the ride plush and enjoyable. 

To conquer the whoops, the RZR XP Turbo EPS 90 in/228.6 cm wheelbase, paired with its 3-Link trailing arm rear suspension, gives the vehicle 18 in/45.7 cm of rear travel and a whopping 13.5 in/34.3 cm of ground clearance. The 3-link geometry allows surface-hugging grip as the vehicle pulls through corners from the use of optimized camber gain, and the length of the trailing arm provides a better ride. Up front, the RZR XP Turbo EPS features an exclusive front suspension geometry that results in less steering effort for easy maneuverability. Paired with industry-exclusive 29 in/73.7 cm Maxxis Bighorn tires on 14 in/35.6 cm cast rims for a better ride and higher resistance to pinch flats, there’s nothing that stands in the vehicle’s way.

Coupled with cab features such as bolstered seats, tilt steering, space-optimized foot rests and factory-installed quarter doors that keep the occupants planted and secure, the RZR ride experience is like no other.

The RZR XP Turbo EPS will be offered in Graphite Crystal, Spectra Orange and Velocity Blue.
