With the Bugatti Veyron having had such a long production run, by now you've seen huge numbers of pictures and videos of the car. Most of this will have had to do with performance, or some of the unique designs of the car's special editions. The engine of this beast is something which is often mentioned, but rarely really explored in depth. So here we have a video of the engine assembly line, where the engines were all built by hand; something still impressive even now after production has ended.
The video is worth watching if for no other reason that it's such a unique type of engine, and it will help you to appreciate that so much more.
