Inside space
Hoping the vast knowledge from locost builders can help me.
Got a project at work were I have been given the task to get official figures on the internal cockpit area/volumes of cars , all the cars are used
in motorsport. Is there somewhere I can get these figures, car sales brochure specifications show boot litres but not cockpit litres or volume.
Help please.
Dave

Not something that's usually published anywhere. Primarily as it's an entirely pointless technical dimension for a customer 
Lots of variables as well - trimmed, untrimmed? doors on/off?

Thanks for quick reply
Yes I agree not usual question you would ask in a car showroom, but this is motorsport and race cars, doors on, usually two seats no back seat normal
dash but the rest pretty much stripped out, wonder if I would get any info if I phoned any race teams.

Have you been asked to find left hand screws, a long wait etc as well?

No it's not a joke, absolutely serious, extracting someone out of a crashed car in a given time when life is at stake using special equipment,
that is the task.

Do you need to collate lots of cars to compare or an average single figure to base some work on?
Depending on your backing \ resource I would consider getting yourself along to a club day \ hill climb with a measuring system. Depending on
accuracy this could be quite easy. A case of measuring the external dimensions and subtracting a sensible amount will get you in the region.
Especially if this is supported by more accurate measurements to prove the external dimensions to internal dimensions ratio.
A nice little project that. Should keep you tied up for a week.
Track days ARE the best thing since sliced bread, until I get a supercharger that is!

Maybe some form of pressure test or vacuum pull could work if you seal vents and window seals with gaffer tape.
Your task has a huge amount of variables..

How accurate an answer are you looking for? Getting the pictures manufacturers put out with external dimensions would probably give a pretty close
answer from calculating external volume and subtracting a reasonable amount for shell space and fittings.
THIS site seems to have some
but I couldn't work out how to navigate and the dimension is in cubic feet but it might help, especially if 5 series was on your list.

My first inquiry would use a standard letter explaining the intent i.e. to provide data to assist Motorsport in safe extraction of people from crashed
race cars, to all major manufacturers and possibly their Motorsport divisions and see what comes back

if this project is not on behalf of the MSA it might be worth getting in touch with them or BMMC, sometimes our yearly training involves extracting
drivers from tin tops. Either of these must have relevant data.

Out of interest - how does knowing the internal volume of the cockpit (before it is potentially rearranged in the preceeding crash) going to be of use
to this?
I'm thinking that the fire service approach to dealing with this is to cut cars apart to extract people - and to treat them in situ...?
