The Massively Successful Polaris RZR-Sponsored Film Franchise is in Production


San Diego, CA – today announced the fourth installment of the Polaris RZR-branded, viral film franchise dubbed XP1K4 is currently in production. The announcement comes with the release of the official teaser for XP1K4, which showcases highlights from the first three XP1K videos; ending with some incredible sneak peek shots from the upcoming fourth video. Motorsports directing heavyweights “The Martelli Brothers” and their powerhouse production team Mad Media will once again be producing the new campaign of adrenalized XP1K4 video content, which includes nearly 30 videos, all in support of the main film which drops mid-January.

“We created the XP1K series three years ago to highlight the progression and evolution of both the RZR vehicles and the sport as a whole,” said Matt Martelli, CEO of Mad Media and the series co-director. “It was a coming of age moment for an entire industry that had just exploded in popularity. Every year since then, we’ve pushed ourselves as a team to go further, faster, and be as creative as possible. The RZR keeps getting better – and that’s allowed us to progress with the series. This next chapter is a continuation of that spirit. It’s going to be another touchstone that all UTV riders – and especially the RZR family – can point to and share with their friends. We have the best fans on the planet – and we’re confident XP1K4 will leave them thoroughly stoked.”

The XP1K viral film series has accrued more than 42 Million aggregate video views across YouTube, Facebook and Instagram so far, and has been watched in more than 70 different countries. The premium-branded, viral video campaign has made hundreds of millions of impressions worldwide, redefining the sport Utility Vehicle (UTV) and Side-by-Side (SxS) market.


Off-road racing champion RJ Anderson returns to the driver’s seat to perform a myriad of awe-inspiring stunts in a highly modified 2017 Polaris RZR XP® Turbo EPS SxS.   This time around, he‘s joined by FMX Champion Jackson “Jacko” Strong. The duo lay down a massive barrage of gravity defying stunts on a custom-built superpark inspired by some of the best motocross tracks in the world.


Polaris RZR is joined by RIGID Industries, Rockstar Energy and BFGoodrich as primary sponsors of XP1K4. Anderson will pilot the all-new, Tony Vanillo designed, Carr One-built, custom XP1K4 168-horsepower RZR XP Turbo EPS. Heavy modifications designed to meet the demands of the project include a Holz Racing Products suspension, front sway bar, front bumper, engine mounts and skid system. The dash cluster features the all-new RacePak iQ3 data-logger, Switch Pros Switch Panel, and Mob Armor Mount with iPad Mini designed for the RZR. Anderson will sit on a custom-made MPI/PRP Alpha containment seat and utilize a PRP 5-point harness and custom XP1K4 MPI steering wheel made specifically for the vehicle.  

Walker Evans Racing has returned and provides their industry leading shock and wheel packages including Walker Evans Racing: 15″ Bead Lock Wheels, 2.5-inch Velocity Shocks and  new Walker sway bar links. RIGID Industries  supplied a host of LED lighting products including the new “Chase” rear-facing, multi-function LED light and the new Rigid “Reflect” LED all-in-one light/mirror. BFGoodrich, the biggest name in off-road tires, supplied their all-new “Baja T/A KR2” 30-inch UTV Tires, which provide superior traction and unmatched durability. The entire car is wrapped in custom Mad Media-designed XP1K4 livery printed and installed by Proline Wraps.


“The new 168hp RZR XP Turbo platform provides the perfect balance of power, suspension and agility to conquer the stunts RJ will throw down in the video.  We’re ready to raise the bar yet again,” said Joey DiGiovanni, CEO of UTVUnderground. “Mad Media has locked down a brand-new location for the filming of XP1K4, this time taking the viewers into a custom–built, motocross-inspired, off-road superpark that’s totally out of this world!”

“We’ve always tried the push the boundaries when it comes to our shoot locations,” said Joshua Martelli, COO of Mad Media and the series co-director. “This time around we’ve come up with an incredible array of stunts and carefully laid them out in the diverse and challenging landscape of the Southern California mountains. Fans of XP1K2 will be particularly jazzed as this is definitely a return to a more natural setting.”
