first of all don't bash americans because we use trucks to tow things

secondly its your car and your problems later on down the road that you will deal with

lastly trunk racks that carry bikes attach to the trunk....hence trunk rack (theres a pun in there) so before u jump down our throats get ur info right

again i will say this its your car and your problems

merry xmas

i never said it will void a warranty or ur drive train will disappear

simply put sedans don't tow and in my opinion the added stress to the frame will in the long run cost u problems therefore in my opinion its worth it to spend 30 dollars for a uhual and 6 dollars of insurance to beat the crap out of a corporate car

No, I bash some of the people that live on the North American continent (hence americans) that use ONLY trucks to tow things and blindly advise other people to tow things with trucks, not with sedans. The devil is in the details.

I wonder how many times have you towed small trailers with your Audi and if yes (I doubt it though) have you noticed any fatigue in the drive train/unibodi. And ultimately, I have failed to hear any logical explanation why europeans can tow things with their sedans and americans (read the above definition in order to avoid confusion) can't.
Maybe here the same hitches europeans use weigh a lot more here than there and that's why the uni-body is so much under stress here and not there?

Not to mention I hear this opinion over and over again. And yes, I'm bothered to spend at least $1,000 to move between cities with all my stuff in a corporate truck that, by the way, often burns gas because diesel is waaaaaaaaay overrated.

i just stick to things that seem logical thats all, you wouldn't take a carbon fiber road bike down a mountain...i mean you could.....but thats not what its meant for

who says you can't use a ferrari as your winter beater car i mean really these are all possible things but logically and theres the kicker.....logically it doesn;t make much sense

again don't get ur panties in a twist because u posted on a forum site saying u were going to tow stuff with ur sedan on this site

people love their cars on audiforums, they go to great lengths to mod there cars so that they are unique to them, so don;t get pissy when u ask people whats the best tow hitch for my a4 sedan and they get upset

As I suspected, you are not able to provide logical reasons, although you're invoking logic to sustain your arguments. My conclusion is that hitches and logic act on different laws on this continent in comparison with Europe for some people.

Dude, drop it dead. I'll be trying to figure it out on myself what to do before mounting that hitch on my car, your explanations were more than helpful - not.

you want logic, ok your towing 1000lbs at 25 mph, no issue that pretty much a force of 3000lbs on ur frame dragging behind because the faster you move the more force is required to drag weight therefore the faster u go the more strain ur putting on the car regardless of frame....so i'm assuming gonna drive on a highway at some point raising the speed to 65mph which is gonna raise the force of the trailor well above 3000lbs, so that tiny little trailer that wont do any damage is now putting incredible strain on your vehicles frame, not too mention the added stress its going to put onto your brakes to slow it down because essentially its the same thing in reverse the faster ur going the more strain ur gonna put on ur brakes to slow the car and trailor down

reasons why we use big trucks to tow things? first of all, the transmission is geared to a lower gear ratio which means the truck won't go as fast but have alot of low end torque to get the trailor moving, next you have a fully boxed frame with reinforced rails to make sure the truck can handle such a load. and lastly most trucks have an air braking system which can handle the intense stress you're going to put on it when braking with a trailor

so theres your logic, theres your reasons but again because u just don;t seem to get it:

it is your car, YOURS not mine so do whatever you want with YOUR car ....you will never see me with a trailer because thats something i would never do, but this is your car so do what u want to it

You're repeating yourself with "it is your car, not mine" - yeah, I properly received the idea, it is my name on the title, not yours.

Maybe I haven't made myself clear and I apologize for that; I didn't come here to listen to furious reasons why should not mount a hitch on my car but I came here to ask question what are the limitations and how can they be worked around. Buying a f. Ford truck doesn't count.

In your physics world the load on car with hitch and trailer it must be a linear function of speed - the force gets bigger once the speed gets bigger - at least that's your interpretation.
In my world, which btw is real world, force is:
F= ma

- m is mass
- a is acceleration
or
F=m(dV/dt)
- dV - velocity vector
- dt - time vector
It's called Newton's second mechanic law - http://en.wikipedia.org/wiki/Force
To have it SIMPLISTIC written down, it looks like at 104.6 km/h (65 miles/h) CONSTANT speed, the trailer attached to MY HITCH ON MY CAR it will still weigh in 453.6 kg (1000 lbs - by the way, the american measuring system sucks). Keep also in mind that the towing limit specified in the car's manual is 907.1 kg (2000lbs).

Also, from a practical point of view, the real force that my car will have to withstand will be actually a sum of forces:

Ftotal=m(dv/dt) + Fd-air + Fd-tires

- Fd-air - air drag force, look here for the equation - http://en.wikipedia.org/wiki/Drag_equation
- Fd-tires - tires drag force

Considering that my car accelerates from 72.4 km/h (45 miles/h) to 104.6 km/h (65 miles/h), the absolutely biggest contributor to Ftotal will be dv/dt, because:
- m (mass) is constant, unless you spit over the window while drivin', but I sense this one is neglijable as well;
- Fd-air increase over the considered speed range is negligible. The key word in this sentence is INCREASE;
- Fd-tires increase over the considered speed range is ALSO negligible. The key word in this sentence is INCREASE;

In other words, it SURELY comes down to how heavy of a foot on the gas pedal you have. You step on it, you leave your trailer behind, you treat it nicely, you reach your destination safe and sound.

For a real life computation of a force look here: http://auto.howstuffworks.com/question497.htm

Check your physics and you might wanna put that truck of yours for sale.

furious words?!....hardly

its actually funny because it is a linear equation....the fast u go (acelleration!!!) the more mass u carry ....force.....equals.....mass....multiplied by......acceleration!!!!!! woweee!! were geniuses here!!therefore if your speed stays the same obviously the force is the same....buttttttt who just all of a sudden goes 65 mph? no one there is an accelration period in which your car will be under strain

now this has gotten laughable because if u spent half the time proving me wrong and spent it looking for a hitch you'd be set

i never said buy a truck thats really expensive dum dum

i said rent a uhaul thats like 34 bucks i know because i buy uhauls!!....for 34 dollars and to behonest you can carry alot more in those guys then u can in ur a4....im sure u don;t need physics to answer that tho...mmk pumkin?
