Polaris\u2019 new Xpedition<\/a>, an all-terrain vehicle designed to tackle tough 4WD roads while keeping the driver and passengers as comfortable as possible. The off-road capability is only half the story of this side-by-side.<\/p>\nWhat Makes a Side-by-Side Different<\/h2>\n I\u2019ve driven my share of off-road vehicles over the years, from four wheelers on my buddy\u2019s farm to snowmobiles in Colorado and my cherished 4Runner built for overlanding. But the side-by-side is a unique category of off-road vehicle. Instead of the open-aired all-terrain vehicles that are designed to get one or two people from point A to point B through rugged terrain, the side-by-side is designed to tackle the same rugged terrain in relative comfort, with closed cabs and surprisingly plush seats. During the last several years, side-by-sides have gotten more posh, with climate control, power windows, sound systems, and infotainment screens.<\/p>\n
These side-by-sides are so capable, and so comfortable, that there are people in Utah and Arizona (where it\u2019s legal to drive them on the roads) that use them as their primary vehicle. I know a guy that drives his side-by-side to the golf course on a regular basis here in North Carolina.<\/p>\n
The Noise Problem<\/h2>\n But there\u2019s always been one glaring issue with these enclosed-cab side-by-sides. They\u2019re loud as hell. The engines have to work at such high RPMs to power these machines through technical terrain that your entire ride is accompanied by the high-pitch sound of an engine working overtime.<\/p>\n
Imagine a car stuck in second gear at 40 mph. That\u2019s what these side-by-sides sound like, and that ever-present hum gets trapped inside the enclosed cabs with no place to go. The first time I drove a side-by-side, I thought the transmission was broken and the vehicle wouldn\u2019t shift. Some side-by-side owners will muffle the sound through after-market sound-proofing, while others wear ear plugs.<\/p>\nThe Xpedition wears the evidence of a South Dakota mud bath after a sudden hailstorm turned dirt roads into slick rock gardens.<\/span> (Photo: Graham Averill)<\/figcaption><\/figure>\nEnter NUMATIX: Polaris\u2019 Fix for the Noise<\/h2>\n The loud noise of the engine is enough to turn some people off of the vehicles altogether, so Polaris decided to address the issue, taking a big leap forward in terms of comfort with their latest innovation, the NUMATIX Controlled CVT. This new transmission uses air pressure to manipulate the clutch and deliver a quieter engine at cruising speeds. I\u2019m not going to pretend to understand the engineering principles behind governing the transmission with pressurized air, but I will tell you that the new Xpedition is noticeably quieter than the previous model.<\/p>\n
Polaris claims that their new side-by-sides with NUMATIX are 40 percent quieter than previous models. You can experience the difference first hand by toggling back and forth between Comfort mode (with the NUMATIX engaged) and Sport mode (NUMATIX disengaged) while driving. The difference is immediately apparent, especially when you reach cruising speeds on a dirt road. The vehicles aren\u2019t as quiet as a minivan, but they are significantly quieter than any other side-by-side I\u2019ve ever driven.<\/p>\n
What this means is you can hold a conversation with passengers in the vehicle. You can tell your daughter to get off her iPad without raising your voice. You can listen to an audiobook.<\/p>\n
I drove the Xpedition for several hours through the Black Hills and listened to music the entire time. The Xpedition has had a bluetooth-enabled speaker system for a while, but there was no point using it in the past because the engine noise drowned out anything you\u2019d play. But with the NUMATIX engaged, I could hear every word and note from Tyler Childers as I dropped into big mud puddles and climbed rock gardens. (Side note: You should always listen to country music while driving off-road.)<\/p>\nGraham Averill put the Xpedition\u2019s new NUMATIX transmission through rock gardens and mud pits in the Black Hills to see if \u201cquiet\u201d off-roading is actually possible.<\/span> (Photo: Graham Averill)<\/figcaption><\/figure>\nPower and Performance in Rugged Terrain<\/h2>\n And the Xpedition still performs like a champ in rugged terrain, providing plenty of power to muscle through technical situations. It has 114 horsepower in a 999cc engine that offers plenty of torque for rock crawling, and 14 inches of ground clearance so you won\u2019t get jammed up in the rock garden. For comparison, the race-inspired Polaris RZR Pro R4 has the same horsepower but in a 1997cc engine and 16 inches of ground clearance. So the Xpedition might not be the vehicle you\u2019re looking for if you\u2019re hoping to compete in the Baja 1000, but for the majority of off-road users, it has plenty of power to get us where we want to go.<\/p>\n
And that\u2019s the real draw of these vehicles. They\u2019ll go pretty much anywhere you want to go in a very user-friendly \u201cpoint and go\u201d package. You don\u2019t have to be an experienced off-road driver to operate this side-by-side through the gnarly bits. Yes, you can get in trouble\u2014I\u2019ve seen people roll their side-by-side because they carried too much speed through corners with loose tread\u2014but for the most part, these vehicles open up hard-charging, off-road adventures to average drivers like myself. Going from a 4WD vehicle, like my F-150 truck, to a side-by-side is like moving from a cruiser bike to a full-suspension mountain bike on technical singletrack. The terrain is so much less intimidating and you\u2019re no longer limited by the tool at your disposal.<\/p>\n
Who\u2019s the Xpedition For?<\/h2>\n That leads me to the ultimate question with a niche vehicle like this: Who is the new Polaris Xpedition\u2019s target consumer?<\/p>\n
First, it\u2019s for someone with money to spend. The Xpedition ain\u2019t cheap. Starting at $40,499 for the two-seater XP, it\u2019s no wonder some people use these side-by-sides as their daily driver. But there are plenty of people reading this column that have dedicated off-road vehicles, and the new Xpedition might be an option for those off-road enthusiasts that want a vehicle dedicated to exploring gnarly backcountry. The Xpedition goes places a 4Runner, or even a Jeep, can\u2019t go. And it can haul plenty of your gear and your people along the way. The Xpedition ADV5 that I drove fits five (or four and a dog) and has an enclosed rear cargo area (36\u2033 long x 47\u2033 wide and 13\u2033 tall) big enough for your Yeti cooler and camping gear. You can load your bike rack into the hitch and even put a roof rack on top.<\/p>\n
I\u2019ve driven models of the Xpedition while toting rooftop tents deep into the Grand Canyon backcountry through narrow canyons I would never take my 4Runner. And with the new, quieter Xpedition, you can have a vehicle that offers that same kind of access and carrying capacity without having to wear ear plugs and scream over engine noise.<\/p>\n
