'kay, somebody explain this humdinger of the new (German) math...
Brochure claims that the coupe's rear seat interior volume (regardless of model and quattro) is 17.7 ft^3. With me still? Good...
Now, the luggage volume of the the FWD model is 13.8 ft^3 and the Quattro 10.8 ft^3. The latter is easily explained, as Audi has created a fabulous loft apartment in the missing 3 ft^3 for Mr. Haldex to occupy...
Still with me? Thanks.
Here's the part that gets me - With the rear seat folded the FWD model has 24.2 ft^3 and the Quattro has only 18.6 ft^3. How is that possible? If the rear seat volumes were the same (see para one above) and the luggage volume due to Mr. Haldex was only 3 ft^3 - how is it possible that I'm being deprived of an additional 2.6 ft^3 (24.2 - 18.6 = 5.6 - 3 = 2.6ft^3)??? Do I need to do some silly ol' volume calculations here? Can I not just subtract one space from the other??? Somebody tell me the relevant variables and I'll revisit, in the meantime - I feel not optimally informed...
Dirty Bastards!!!- I mean, where did the space go? I want it back!!! They can't just go about taking people's bloody space!!! That's enough room for one more Moose Head!!!

I believe the answer lies in the fact that you are trying to figure out a brochure . ..
that has very few items correct in it! It is entireley possible that the difference in ft^3 between the FronTrak and Quattro is wrong and the other numbers are right. It is also entirely possible that NONE of the numbers are right and the number actually came from an A3 Diesel! I am serious.
Read through any TT brochure and find all of the errors, they are plentiful!
To make your life easier . . . the FronTrak storage area is about 4" deeper than a Quattro. You may now do your math from there.

The way we used to measure airbag volumes was to fill them with pingpong *****.
and then start counting. Many other methods were tried, but the ping pong ***** was always the easiest and gave suprisingly good results.

That's messy, but doable. How about this method?...
Define the space with a partition, if needed (like for rear seat area).
Obtain a quantity of lightweight spheres (1 cm plastic ***** work well)
Fill the cavity with the *****. You may need to tip the car some.
Because the ***** will "cubic close pack", you can then pour the ***** into containers of accurately known size, like 1,2,5 ft^3, for example, and get an accurate cubic measurement.
Obviously the smaller the ***** the more accurate the measurement. Interestingly, vehicles are EPA classed by interior volume which is measured using (don't laugh now) SAE Recommended Practice J1100 as per EPA Fuel economy regulations, reg. 40 CFR 600.315-82 "Classes of Comparable Automobiles." Automobile manufacturers calculate the interior volume of their vehicles and submit this information to EPA.
The SAE procedure calculates interior volume from many height, width and length dimensions inside the vehicle, including head room, foot room, seat width, etc. The trunk volume is typically determined by putting many suitcase sized boxes in the trunk and adding up the volume of each box.
Strange, huh?
