If you get a chance, try and watch the Nat Geo special on the Veyron. They go into detail on the design and building of the car, and it is very impressive. Half of the fabrication work for the car is done by a German aerospace firm that builds fighter planes and rocket shells for the EU. They had to build a new engine dyno because the W16 nearly BURNED DOWN the old one because it produced so much heat energy. Every radiator on the car is hand built, as are the exhaust manifolds and exhaust system. The whole exhaust is made of Inconel and Titanium.
