Well... the F150 I towed the second 6000 lbs boat with burned 10 MPG (24 l/100) at decent freeway speed. Still not sure if it was a V6 3.7l or a V8 5.0l but I presume a V6 as Uhaul would not offer the better V8 motor most likely. So 10 MPG for a powerful and fun to tow V8 X5 would be very much acceptable.... Of course, nothing compares to the diesel, but then, the V8 would really tow with ease.... One would not feel anything with that much HP and torque.

You could tow 7k with ease for LOOOONG distances with the 50i V8.

Don't ask me how I know. Wayne, don't tell them LOL.

As others have stated, the X5 5.0i has no problem towing. My wife routinely tows two horses (BIG horses) and a trailer with hers. Going downhill with a strong tailwind, she can get 12-14 mpg.

Uphill or with a headwind... don't ask.

Pick up the trailer. Everything works fine. Programming worked on OEM setup.

Open car trailer weights 1900# about. I plan to load up my DE car next week (3200# pig)

With equipments and tools, Im guessing 5500# on the trailer and about 100# of "luggage" in the X5 hauling at the end.


I do feel that I am pulling something obviously, but Im driving slow in the most right lane trying to get used to the whole dynamic of this.

My 2012 50i seems to want to stay on 8th gear. X5 doesnt have tow mode and sometimes i need to shift manually to 6 to get it going on the hill.

I am thinking of the X5-D and my towing requirments are over the 6K rating, but I only tow localy, about 4 miles to boat ramp. Would towing a 7,200-7,500 pound boat and trailer (Pachanga 27, with twin small blocks on dule axel) be too much for the X5-D. Assuming this is OK loclay, any recomended set up's.

^^ You would be towing over the limit. Not sure what hitch you are using but the NA hitch is rated only to 6k pounds. The X5 itself has been rate to 7700 lbs in some European literature from BMW's site. While I think that the car is capable, you may run into an issue if you have any sort of accident with insurance denying your claim.

Thanks for the info. If I can figure out which hitch to use, I would be inclined to go for it. I live four tenths of a mile from the boat ramp, and < 2 miles from the place it's stored in the winter.

Anyone have suggestions on the proper hitch for my application, and the best place to purchase.

Contact Daryl at Invisihitch. He is a sponsor on this site, do a search and you'll find his information.

IIRC, their hitch is rated at 7,700 lbs, but Daryl can give you more information. I have their hitch on both of my X5's and it is the best hitch on the market for the E70, IMO.

Good luck!

I believe the Execuhitch/Invisihitch is rated higher than the factory (I think it's 7700lbs... don't quote me on that though)

rear of my x5 sags - i should weight fully loaded tongue weight. Also another thing I experienced was 4x4 xdrive warnin sign when climbing up a mountain on a VERY hot day. This was after 6 hrs of driving hauling the trailer. I think tranny got really hot. I will probably position the porsche few inches back as it is rear heavy car. I just ordered Shoreline scale so i will weight the tongue and make adjustments.

^ I had a good offline discussion a few weeks ago with Mick ("digdesign") about the tongue weight on his setup, which is very similar to yours. You may want to reach out to him. He's got it down to a science, both with and without a loaded wheel rack at the front of the trailer.

You can tow heavy with the X5. But you really should watch your tongue weight very carefully. The normal forward/aft forces of towing act directly on the horizontal "frame rails" of the unibody because that is exactly where the hitch attaches. So you've got tension/compression acting along the full length of the vehicle's beams. But tongue weight tries to torque the rear chassis panel. If it were my X5, I would keep the tongue weight down to 450 lbs, despite BMW's higher rating.

^^ If you move too much of the weight to the rear of the trailer, don't you risk trailer sway? I know people trash talk the self levelling suspension, but the bags don't seem expensive or difficult to replace if you have an issue. It also allows for a higher rear axle load according to BMW's documentation.

Optimum tongue weight is always an interesting discussion. The theory is that you want enough downward force on the ball to provide resistance to "floating" because when the trailer coupler starts floating on the ball, the trailer will be more apt to sway side to side. However, the amount of downward force that is sufficient to provide the desired resistance to floating is much debated.

In the States, it is common to use a 10% rule of thumb for the ratio of tongue weight to towed weight. In Europe, where towing is much more heavily regulated, it is not uncommon to see that same ratio be as low as 7% or even 5%. In my opinion, it is not merely a coincidence that, in the States, you see many more large, box-style trailers that offer high wind profiles, whereas such trailers are relatively uncommon in European countries.

An argument can be made that the ratio of tongue-to-towed weight is the wrong metric to use to prevent coupler float because wind resistance becomes the dominant factor at highway speeds, and highway speed is the only time that trailer sway becomes an issue. I would personally use much higher tongue weight for an RV than I would for a cigarette boat of the same weight because their two wind profiles are entirely different.

In practice, I tend to largely set aside the ratio rule-of-thumb and instead I just load the tongue all the way up to a weight that I am confident will not damage my vehicle. I'm conservative about that number, so on an X5 it would be about 450 lbs for me. There is always the lurking pothole seeking to jar that weight downward...

I agree. I've been meaning to pick one up to have as a spare. I occasionally do 10-12 hour tows, and since they're easy to replace on the side of the road it seems like cheap insurance.

Any possibility that I can't get to 450# of tongue weight even if I try to move the load to the back of the trailer? On a 5500# loan, 450# would be less than 10% TW... I know BMW doesn't recommend WD devices but I would think it is actually safer that it gives more range of "heavy load" tongue weight to be within safety range

The purpose of distribution bars is not to give you leeway with the trailer load distribution. You still need to shoot for a tongue weight that is 10-15% of the gross trailer weight. If you move the load rearward to try and tow with less than 10% on the tongue the trailer will become unstable and could be at risk of going into a dangerous sway. (Especially when coasting down hill)

Hauled some yard waste to the dump with a little Uhaul today. The Invisihitch 2" drop ball mount levels the trailer perfectly.

I just installed my hitch and towed the boat for the first time. The X5 pulls very well, power with the 4.8L was not fazed by the 4,000 pound trailer, could not really tell it was back there. I went up some very steep long hills on the HWY at 70 MPH, no problem. Brakes were great.

One issue, maybe solved by Post 123, Softride.

My hitch is making popping and cracking noise although the bolts are torqued and I really don't think anything is moving. Maybe it is the receiver moving in the hitch? I really did not look to see if it has excessive play.
When hooked to our Chevy Tahoe I have never heard any of these noises so I think it is Hitch related. I used a Drawtite hitch, it fit very well and looks good on the car.

Just got my hand on cargo 7x14 for my move yesterday. First though - damn, how my X5 will do it? Keeping in mind all pictures I saw here I though it will be fine and that how it was.

I barely notice it behind, except hitch rattle on bumps, ordered Silent Pin to reduce that.

Overall, I was very impressed! I was expecting something like that based on what I've read but trying by yourself is different story!

Will post my pics soon too.

What kind of hitch did you get?

Do X5s have transmission coolers? I am guessing not, and if so, any of you guys (especially those towing heavier toys) thought about it?
