For everyone saying to not tow a PWC with an F30 and leave it to a pick up, why?

F30's share the exact same ZF 8HP transmission that BMW puts in their X3,X4,X5 and X6.

An F15 X5 35i has the exact same transmission and the exact same engine as a F30 335i, N55B30MO. This X5 has a 6,000 pound tow capacity.

Pair that with xDrive and m sport brakes in a F30 335i how is it not a capable of pulling 1 PWC at 1,200 pounds, and in the PWC world thats on the heavy side.

do all hitches require some modification to a stock component like the heat shield?

I'd like a hitch, but I like to.keep my car as original as.possible. cutting and removing prevents that.

The F30 has enough "power" to tow a substantial load a short distance at lower speeds, but it doesn't the mass, wheel base, and suspension for towing loads at highway speed to deal with trailer sway.

But if you don't believe me (or manufacturer recommendations), please try it at highway speeds for more than an hour with a forward and rear facing dash cam and report back.

That all depends on your definition of highway speeds. In Europe max speed pulling a trailer is 80kph (90 or 100 in some countries) and a BMW dealer will happily install a factory hitch on any of their cars. An F30 should have no issue pulling a trailer if you keep it under manufacturer recommended load (per BMW Europe) as long as you keep it under 55-60mph.
If your definition of highway speeds is 65-75mph then I agree. BMWNA will recommend against towing with an F30 because there is no special speed limit for car+trailer. It's not a function of the F30's capabilities (or lack thereof) to tow, but the difference in traffic laws.

Regarding towing I quite like this article: https://oppositelock.kinja.com/tow-me-down-1609112611

If you can't keep up with traffic here in Maryland, it isn't safe. Regular cruising speed on I-70 is 75mph to 85mph. You cannot be serious about doing 55-60mph on a highway like that. You're going to get rear ended by someone.

We have an X3 35i and a 335i. There's no way the 335i would be able to tow 2000 lbs the same way the X3 35i would on a highway. It's impossible.

Now a PWC probably doesn't weigh anywhere near that. You could probably do okay using a 335i to tow 1 PWC. It's less than half the vehicle weight.

Nope but after seeing my buddy launch his jet ski serveral times with a gmc 2500 denali, I would never attempt using a 3 series to do the same thing. Even with what I'd classify as a large pick-up, it still goes mid-rear wheel high in water
Agreed. I'm sure the car would be fine regarding the load of a jet ski (I did it back then with an old Honda Civic!!!) but I wouldn't be comfortable putting my car half wheel into the water..

I admit I was afraid of doing it the first time and used a pick up truck. Then I used our F31 to lower the seadoo in to the water. I kept the car running and it Worked like a champ as seen in one of my posts above. The ramp incline was adequate and I would not do it in places where there is no boat ramp. Gobs of grip and ease of use.
Highway use was easy as well. Towing at 75 mph in a diesel was easy and smooth. The car was also loaded to the gills with family, luggage and bikes atop. The total weight with the seadoo and the trailer was between 1000 and 1050 lbs.

You could use a hitch receive extension so less of the car is in the water.

1000-1050lbs for a 3500lbs tow vehicle should be pretty manageable. Powertrain has little effect on the stability during towing. It's largely a function of chassis, wheelbase, and tow vehicle weight.

Calling bs. Vast majority of trucks on the highways are travelling well under 75-85mph. Took an old car cross country doing 55-60mph with no problem at all. Just stay in the rightmost lane, be mindful of slower overtakes and look out for all the idiots on their phone.

I regularly tow a 1600kg caravan with my F36

Only problem with 75mph is 15mpg (imperial)

Highways around you (CT) or highways around me (Western Maryland)? Are you talking about highways in CT within commuting distance of NYC?

You won't even get pulled over here unless you're doing 85+mph here on I-70. That's the general consensus from the state/local LEOs on one of the federal task forces here in MD.

To get back on topic, I don't think a PWC + trailer will be unreasonably heavy for a sedan to tow. It's less than 50% of the weight of the sedan.

However, if you think an F30 N55 can tow just as well as an X3 35i or a X5 35i/50i because it has enough or same amount power, you're out of your mind. If that was the case, than a sports car like a Porsche or Corvette should be able to tow just as well as a 1/2 ton or larger pickup truck.

Trucks / SUV's are made for towing and are better suited, not cars. Just because a car may have enough power to tow something doesn't mean it should, there's more to it than that. Plus with people driving 90+ on the interstates when the speed limit is 70 - 75 and rule of thumb is 80, people on their phones, cutting others off, driving like they're in a Fast and Furious movie, etc., it's not very safe.

Trucks generally get 10mpg towing even small trailers. A 328d gets 20-30mpg without a hint of sway at 65mph with a 2000lb trailer.

Obviously doesn't help you guys who need to fit an aftermarket hitch - but the BMW factory fit is a thing of beauty. One button press and it swings into view - press again to retract to goodness knows where. No filthy hands and no sign of it when not in use.
I tow a utility trailer (small) sometimes to save putting garden waste etc. in the car. I also occasionally tow a sailing dinghy. 4 Series has no problems although I find it better if I take the car out of auto and choose the gear myself - the auto box can't cope well with the changed profile.

The 50mm powered swan necks are not compatible with the 2" US couplers. I have yet to see an Oris or Westfalia solution that will work in North America.

True, but you can tow a utility trailer or camper that weighs under a ton with a tongue weight under 250# without a 2" coupler. A 3-series frame could not handle a weight distributing hitch, nor could the rear subframe or rear suspension handle a greater tongue weight. As it is, I had to install spring perches for the rear coils to avoid too much squat with even 150# of tongue weight. The BMWs not destined for North America even include a towing aid module for anti-sway. One can retrofit the module in NA and code it, but even Bimmercode lets you re-enable features like tow hitch rear camera view that are also disabled for the NA market.

2. Of course with the hitch in place the heat shield can't be put back on without modifying it. After trying to precisely cut around the hitch it still wouldn't fit, so I just cut the rear half of the piece off (just past the 90° bend so it still has a little structure) and reinstalled it.

Hope that helps in case anyone out there is still thinking of putting their own hitch on.
