Overall, 339 types of Lego Technic pieces have gone into it and there's not a single drop of glue holding the auto together, we're being told by Bugatti.
Stores and parks will feature the exciting design for viewers to see in person and it will be officially unveiled first at the Grand Prix Forumla 1 race in Monza in Italy on Sunday.

What's most impressive about this is the fact it actually happened, but also the amount of Lego used in the project.
LEGO made several firsts for this build. Further, it took nearly 13,500 hours to build and even though it's not 100% LEGO parts you have to admit that this is a pretty impressive feat. The full-size LEGO Bugatti was built in the LEGO facility in Kladno, Czech Republic with a core team of 16 specialists.
He added that driving the LEGO Chiron was "a great experience" and that he never thought that the day would come when he would drive a LEGO auto.
At full clip, Lego estimates a top speed of about 19 miles per hour, which is pretty good for a 3,300-pound hunk of plastic and steel running on air and electricity. In fact, from about 20 metres away it's not obvious that you are looking at a LEGO vehicle.
