There are a lot of things you can do and build with Lego, and even people who don't work at the company can build some spectacular creations. Lego is teasing something new and "impossible", though, and it kind of looks like it built a proper car. A car that looks remarkably like the Bugatti Chiron.

The scale of those pieces is certainly about right for a full-size car, and the hashtag #BuildforReal certainly implies that it's gone and built the real thing. I still feel like going a little bit bad to even suggest this idea, but it kind of makes sense. It's certainly the kind of PR stunt that would get Lego a lot of attention, and the kind of thing that would look good on display at Legoland. That's assuming people won't be allowed to drive it, because the health and safety people would probably have a fit.
Then again I may just have a massive dose of wishful thinking here, because it's way more likely that Lego just built a 1:1 scale version of the Technic Chiron set. That would be nice, but it wouldn't be nearly as cool.
We'll find out for more in a week, on 30th August. Hopefully Lego won't drag this out with a bunch of obvious teasers, like it did prior to the launch of the Aston Martin DB5.
