Solved: Welcome to the Pleasuredome

[Craig Gillingham]

This a bit of guess work, O is the Z-Boat designed by British architect Zaha Hadid, who also designed building 12?

I'm quite sure that n.17 is Lingotto factory, Turin, the spiralled ramp to reach the roof circuit. Maybe Q is a picture of the 2006 Winter Olympic Parade of Turin.

Q is carnival in Sao Paulo, this links to 11, a photo showing the 50,000th GM built in Sao Paulo.

You are right about the boat and its designer, but wrong about the building. #12 was already identified as McLaren's Paragon.

You are right about Lingotto, but wrong about pleasure Q....

... because this is correct. Well done!

Yes, the first building by Zaha Hadid that was realized.

Besides from the typo (it's Deutsche Bank) that's correct.
The Kar-a-sutra made its appearance here before: http://www.autopuzzles.com/forum/index.php?topic=11490.0

I is the Tour Perret a residential skyscraper in Amiens, France, by Auguste Perret.           

5 is the Rue Ponthieu Garage in Paris, France, by Auguste Perret.

Amazing performance! Right again!
The Rue Ponthieu Garage was the world's first building made of reinforced concrete. Unfortunately it was demolished in 1970.

One last shot (and this one is pure guesswork) and I have to leave the Pleasure Dome.

H & 8

H is obviously a photograph of Elvis Presley.           

8 is the 'Kugelhaus' designed by Egon Brütsch, in 1959.

I'll guess that the connection is 50's culture.

H is Elvis, 8 is Brütsch's Kugelhaus, all right. But they don't pair and the connection to their counterparts is more substantial than just the same decade. Just keep on digging! 

All other experts are invited, too.

Yes, that's the ticket.

Everything correct what you said, but there is a little bit more about Pleasuredome E.
E-8 locked for you.

Not sure exactly what you are looking for, and I haven't been able to locate anything detailed specifically about picture E (like where or when), but, since this is AutoPuzzles, I'm guessing that you are looking for how Egon Brütsch relates to cars.

Before he began designing houses in the late '50's, Egon Brütsch was a race car driver who contributed to the design of his own race cars in the late '40's. In the early and mid '50's he designed a series of several different models of micro cars, all using molded composite bodies consisting an upper and lower portion, the joint of which showed as a horizontal line around the vehicle.  The car in the picture doesn't look like any of his several commercial designs that I have seen, but it does have the characteristic horizontal line, so I'm guessing that the car in the picture might be some sort of "proof of concept", or maybe an additional design specifically for children (perhaps his own).

Yes, that is correct. Please provide the name of this children's car. Still locked for you.

I guess M and 17;  M is a masterpiece of Amedeo Modigliani, and I think it may belong to Gianni Agnelli's collection, that is exposed in a wonderful structure realized on the roof of Lingotto, Fiat factory from the '30. And 17 is the spiral ramp of Lingotto.

Yes, it does. Well found!

It looks like I'm going to have to "toss in the towel" on this one.  I have searched everywhere that I can think of, but have been unable to locate any children's car designed by Egon Brütsch, let alone find its name.  I have compiled a list of names for Brütsch designs (Avoletta, Belcar, Mopetta, Tourette, Pfeil, Rollera, Zwerg, Zwerg Einsitzer, Bussard, Spatz, V-2, V2N, 400, Jet), but all of these appear to be for adults, although they are microcars.  

Thanks for the lock, but I guess we're going to have to open it up to an Expert who has better references than I.  I hate to give up when I am this close, but I have had a good run in the Pleasuredome, so I don't need to be greedy.
