The shipping weight that is printed on the invoice of each vehicle is not really for that specific car, but the non-optioned base model of that trim (i.e. GT Deluxe Coupe Manual). For example, we get a lot of Mustang GT automatic coupes with a ton of different options on each, yet every invoice says the exact same shipping weight even though those Mustangs each weigh dozens of pounds apart from each other. The shipping weight on every 2008 Mustang GT automatic coupe invoice (deluxe model and premium model, FYI) that I looked at today was 3,398 lbs, but the Ford Source Book says the Base Model Curb Weight is 3,532 lbs (134 lb difference from shipping to curb weights).

Keith - just curious where your .pdf file is from? Not doubting it, just curious who the source of your info was. The info that I've provided is not nearly as detailed as what you have, but I've tripled checked that it is accurate as provided by Ford Motor Company.

I did some more searching through the 2005 MVMS manual I posted earlier, and it shows that the Tremec 3650 manual trans weighs 122.5 lbs, while the 5R55S auto trans weighs 174 lbs, a difference of a little over 50 lbs. Anyone actually weighed their transmission? A weight difference of 184 lbs does seem a little high to me, but I've been wrong before.

Rocky, Karman is right. The shipping weights on the invoice are mostly for registration fees when you license a vehicle. It will determine whether any excise fees get charged in addition to regular license tabs. This is especially important for trucks. Also, there are federal tax credits available that depend on shipping weights, so manufacturers ease the fed's info requirements by providing a base shipping weight on the invoice. Also, here in the Seattle area, we ship a lot of new vehicles to Alaska and the shipping companies need an approximate weight to calculate charges for their customers. Additionaly, there are some EPA and governmental legalities that have some basis in the type of vehicle and its weight, so I'm sure that's yet another reason to post the shipping weight on the invoice.

The posted Base Model Curb Weights are likely the most accurate reflection of reality. And physically weighing the car is the ultimate reality as even identical cars can vary a bit in weight, much like horsepower can vary from the factory on "identical" engines due to production tolerances.

In other words, according to my vehicle's title. It claims that my car weighs 3315 lbs. So exactly what is that referring to ? shipping weight, or something else.

I have 3315 lbs as shipping weight in my original title.

Here in WA state, our registrations & titles list a value code and a base weight to calculate license fee renewal amounts and any excise taxes owed with the license renewal. I suspect your state is similar, and I suspect the 3315 lbs is likely a base weight without options. You may want to call your state's department of motor vehicles for clarification; they would know best.
