I've been slowly building up my 2015 CD for mild off road usage. I've added a Eurowise 2" lift, fitted 265/65R18 BFG KO2's on Alpha Grenad wheels, DirtCom swing out tire carrier, Eurowise winch plate w/o a winch as a recovery point, the complete underbody protection kit (skid plates and rock rails) from Eurowise, removed the rear seats and made my own sleeping platform. I've installed a 50qt ARB fridge/freezer on it slide, and made a cabinet to house a small microwave oven. I'm using a EcoFlow Delta 2 solar generator as my secondary power system. I've added a ham and GMRS radio, and iPad Mini to a Ram Mount system that got attached to the front center dash.

I picked up a Crux PCM interface module so I can run both a front and rear camera (currently my rear camera is blocked by the swing out tire carrier). I haven't figured out how to run the front video/power cable into the cab from the engine compartment. Does anyone have a solution?

I'm also wanting to add the Titan Fuel Tanks Trail Trekker II 12-gallon transfer tank the sits behind the spare tire. I haven't been able to get any sales person to get their heads around the 5x130 lug pattern verses the Jeep pattern used on the JK/JL Wranglers. Seems doable; looking for a dealer that has one in stock so I can do a quick fit check.
Over the past 18 months or so I've been slowly upgrading my vehicle so we could enjoy the same trails as the over-landing club I was part of. I was admitted into the club as an experiment as their bylaws state no AWD vehicles allowed. I have done moderate trails such as the East Mojave Heritage Trail (EMHT) (CA, NV), northern parts of the NM BDR (NM), ghost towns of SE Arizona, San Rafael Swell (UT), and just recently a long backcountry expedition into NV, ID, MT with that club.

Upon returning from the central Idaho trip I was notified by the club I could no longer be a member as the experiment had failed. They sited for my safety I couldn't use the AWD vehicle but would be welcomed back into the club with a proper 4x4 vehicle. The main reason for the clubs ruling was the recent National Park Service news reports of warnings and fines being issued to AWD vehicles using NPS 4x4 only trails.

I had demonstrated the CD's capabilities very well over all these "moderate" trails and even after the EMHT the JK and Gladiator drivers jokingly referred to the trail as being "Porsche Rated".

Clearly there will alway be a bias against AWD vehicle by some of the 4x4 crowd. I am struggling to forgive them for their ignorance.

BTW, after the ID trip with stretches of trail with no gas stations within miles, I had equipped the CD with 8 gallons of diesel in ROTOPAX's and never need a drop of fuel from them. I have abandoned the idea of adding extra fuel caddy and will maybe only bring one 2 gallon ROTOPAX if I really think it is needed.

The capabilities of the CD are just outstanding especially when given a little bit of lift and using common sense on trail selection. Soooooooo much better than my JK for long distance comfort and even trail comfort for that fact.

Sorry to hear that. I'm sure you made some good friends and there were those who felt the same about you and your vehicle's performance.

Unfortunately, they sometimes have to create rules for the least common denominator, which is people in their AWD Hyundai thinking they can do the Mohave Trail.

We are officially signed up for the Alcan 5000 and at the moment the Cayenne is a hot contender. I found out that you can get a 2012ish with V6, tow hitch and extended fuel tank as an option. I missed out on one 2 weeks ago.

I found one. Hybrid. For some reason the Hybrid version seems to have more options and cost more new, but actually is cheaper used than the non-hybrid.
Perhaps the complexity scares people?

Christian, which Alcan 5000 are y'all signed up for?
As members of RASC living in the PNW we did two w our 2013 Cayenne diesel. Both were winter events 2016 and 2020. Please let us know if you have questions or if we can be of help.

We are signed up for the upcoming Summer 2025. My wife and I with a vehicle and 2 of my friends on motorcycle.

That is totally absurd- basically outdated assumptions based on the limitations of old vehicle technology.

A more modern way of looking at this would be something like how much static torque from a standstill can the drivetrain apply to each individual wheel under various loss of traction conditions, e.g. with between 1-3 wheels on rollers or in zero traction situations. You then consider the wheel diameter, and compare the forward force from a single wheel to the total loaded vehicle weight, to see how steep a grade you can climb in theory with traction on only one wheel. That's what actually matters for not getting stuck- and I'll bet 958 Cayennes exceed most traditional 4x4s by a huge margin in the ability to actually deliver torque to the wheel(s) with traction.

My old 1986 Isuzu Trooper diesel with manual trans, open diffs, little suspension flex, and only 88 ft*lbs of torque would be allowed in their club, but I'll bet your Cayenne can transfer an order of magnitude more torque to a wheel from a standstill without having real 4x4 or low range.

Warning: math! Some calculations to compare a traditional 4x4 diesel SUV with the modern Cayenne Diesel- to see how the lack of low range and locking center diff impacts the ability to provide forward motive force to individual wheels with traction.

C223T powered Diesel 1986 Isuzu Trooper has 88 ft*lbs of torque, 4.56:1 final drive ratio, 3.785:1 1st gear (5 speed manual), 1.87:1 low range for a 32.28:1 crawl ratio.

A 2015 Cayenne Diesel has 405 ft*lbs of torque, 3.27:1 final drive ratio, 4.97:1 1st gear, no low range. Let's assume the automatic trans torque converter gives you an additional 2.5:1 torque multiplier. The CD transfer case can only deliver 60% of torque to the front axle and 80% to the rear with no lockup.

So the 2015 CD can in theory put out 405*3.27*4.97*2.5*.6= 9873 ft*lb of torque to the front axle, vs the trooper "real 4WD" which can manage only 88*4.56*3.785*1.87=2840 ft*lb of torque total with the clutch slipping at the torque peak.

So despite the "lack of 4WD" we are looking at on the order of at least ~3x the actual torque to traction wheels of old low powered 4x4 vehicles, which were/are quite capable offroad. With excellent Porsche/VW/Audi traction control system you also get all of that ~10k ft*lbs of torque to any single wheel, even if it's the only wheel with traction.

Now let's say you have 31" tires on the CD, with a radius of 15.5 inches. That gives you 7643 lbs of forward force from any single wheel, on a vehicle with a GVWR of only 6,327 lbs.

That means in theory, if you have the traction, there's enough torque to a single wheel to easily lift the vehicle vertically. From that, you can argue that there is no possible offroad scenario (steep grade, etc.) where the CD's lack of a low range or locking center diff can cause the vehicle to get stuck due to inability to deliver torque to a wheel with traction.

Now, I do think there is some advantage to low range and a center diff lock in terms of making it easier to creep slowly, with less thermal load on the transmission and transfer case. But the Cayenne is so overbuilt I highly doubt the trans will overheat offroad, and if it does, you can monitor it over an OBD reader and stop to cool for a bit.

Let's also now consider a 2015 base model Jeep Wrangler with a 3.6 liter V6 and 6 speed manual. This has a 4.46*3.21*2.723=38.98:1 crawl ratio with 260 ft*lb of torque. Stock tires are 29.3" (radius 14.65). So this gives a total forward motive force to a single wheel of 260*38.98/(14.65/12)=8301 lbs.

So impressively, the CD actually still delivers about as much forward force through it's front axle as a modern manual trans base model Jeep Wrangler.

Excellent write up. I appreciate your examples. However, you know as well as I do, they were just looking for an excuse to boot my vehicle from their activities. Over the past 2 years I've been with the club, I've only seen 2 non-Jeep vehicles; 1 Ford F150 4x4, and 1 Toyota Forerunner. The balance of the "4x4" vehicle have been Gladiators, JK's, and JL's. I think it scares them to have a non-Jeep out on the trail should it breaks down; no one would know how to work on something other than a Jeep! In reality, most of these members don't work on their vehicles as most are retired. Again, I was told I was let into the club as "an experiment". Ha Ha.

Yep, it's just annoying. I've never tried joining a club, but get a lot of uninvited and unwanted "advice" from strangers about my Touareg diesel, telling me I shouldn't be out on trails with it.

Ultimately, it seems that some people are angered by the idea that a vehicle that doesn't look the part visually is doing the same trails as them. They incorrectly assume it's not offroad capable at all, and therefore there are only two possibilities they can see: (1) that their driving skills are severely lacking if they require a far more capable vehicle to do the same trails, or (2) the driver of the other vehicle is a reckless idiot and is guaranteed to get stuck/hurt. Since #2 is the only ego saving option, they're going to stick with that one.
