The reveals for Monterey Car Week are coming in like a tidal wave. While many are predictable or others too numerous to create as posts, Bugatti has dropped a bit of a bombshell during the week of the event itself. On the Bugatti Instagram page, there is a new concept that isn't much more than a headlight cluster, a couple of overly contrasted front fascia lines, darkness, and suspenseful music.

Bugatti will reveal the hypercar at The Quail: A Motorsports Gathering event this Friday, August 19, at 1:20 PM EST (10:20 AM PST). After that, the mysterious Bugatti will likely be on the Concept Lawn at the Pebble Beach Concours d'Elegance on Sunday.

But what exactly is this mystery Bugatti? Well, you can be certain that it will be a limited-run special, if not a one-off, and we think it will be a convertible, but not a Chiron Roadster. Indeed, Bugatti has always maintained there will be no roadster ever produced for the Bugatti Chiron, so what is this?

"Unlock an icon," and the name of the venue of the car's reveal are all that Bugatti has offered in its Instagram post. We reached out to Bugatti for more information, but the company's Instagram and Twitter posts are all that have been released to the media and its followers. But there is some information to be gleaned.

First of all, there is the $18 million La Voiture Noire, a one-off Bugatti sensation that found one lucky buyer in an incredible low-volume effort for the Molsheim, France-based company. The front daytime running lights are certainly similar to those of the Chiron-based La Voiture Noire, which suggests a complex design and bespoke bodywork. This unique machine is almost guaranteed to be underpinned by the Chiron but will look altogether different.

There are further clues, and they lie in the hashtags Bugatti used. Note the use of #OpeningUpNewHorizons that Bugatti has only so far used for posts of the Bugatti Grand Sport and Bugatti Grand Sport Vitesse, both of which are open-top vehicles. We, therefore, predict that this special edition will let you feel the wind in your designer toupee. In addition, Bugatti recently reflected on owning the top speed record for a roadster for 10 years now, so it's a viable - albeit unlikely - theory to imagine that the new Bug could be built to cement ownership of that record and protect the title from Hennessey and its Venom F5 Roadster.

UPDATE: A new post showing Bolide-inspired taillights and a subtle adaptive spoiler comes with the caption "The last of its kind," which indicates to us that this will be the final pure-combustion Bugatti, with electrified offerings sure to follow from the French automaker's wedding with Rimac. Thus, we suspect this will be more of a beautiful art piece than a record breaker. Either way, the end of pure combustion is nigh.
