Unveiled at last year’s Frankfurt show to a very select audience, the “four-door Veyron” remains a concept for now, but new images have surfaced showing the Galibier in black.

We like it considerably more this way, rather than the exposed carbon and blue shown before.

These new photos have also given us a chance to notice a few more details about the superfast auto – like the illuminated logos on the rims.

With a gorgeous design, this luxury 4 door sedan packs a 8.0-liter 16-cylinder engine with two-stage supercharging and can reach speeds of 220 mph.

The engine is flex-fuel compatible, meaning it can run on ethanol.

The Bugatti Galibier rides on a four-wheel-drive system and features ceramic brakes and a new suspension design that enables “agile, always-sure handling of a saloon of this size.”

The 16C Galibier features a Bugatti radiator grille, LED headlights, a split rear window, an eight tailpipe exhaust system and a Swiss made Parmigiani Fleurier dashboard clock that can be transformed into a wrist watch, pocket watch or table clock.

Unlike many other concepts, the Bugatti 16C Galibier actually has a good chance of going into production and is expected to be available by 2012 for as much as $1.5 million.
