Honda accord - The cog.
The advert was put together in a very clever way.
Believe it or not evry part of that sequence was filmed, it was not fake.
Because the sequence was so long and the studio they were filming in was so small the team filmed it in bits and made the cuts on simple parts like the pins on the car bonnet.
Also its the best advert of all time for me, because its original, creative and shows how all the parts of a honda accord car come together to form the finished product.
Hope that helps you!
