Last week, Bugatti had its first U.S. unveiling of the 16C Galibier Concept in Southern California. Introduced as the automaker's first modern four-door sedan, the 16C Galibier Concept is a close look at what the production 16C Galibier will resemble when it goes on sale in about three years (with a sales price estimated to be about $1.6 million).

In person, the deep blue carbon fiber and polished aluminum bodywork of the 16C Galibier Concept was quiet impressive to those that attended. The sculpted headlamps of the Galibier speak volumes about the company's century-long history and attention to detail with its miniature LED bulbs that circle the main lens. Bracketing the perimeter of each lens are two more rings emitting a bluish light – these irises are emblazoned with the illuminated Bugatti logo.

The most controversial styling of the 16C Galibier is found in the rear. In photos, it looks the same as Porsche Panamera, but the additional sculptural detailing in the Bugatti – including a prominent taper as the "spine" drops below the beltline – differentiates the two. Eight individual polished exhaust pipes, and tail lamps as hypnotizing as the headlamps, make the Galibier more aesthetically pleasing to the eye.

The interior features four bucket seats – each with an artfully sculpted aluminum headrest support. Primary analog instrumentation (speedometer and horsepower gauge) is placed prominently at the center of the dashboard for all passengers to see. Secondary digital instrumentation is contained on a large display set behind the steering wheel. The center console housing the flush transmission selector is rather uncluttered. It continues into the rear passenger compartment where it mimics a flying buttress – open at the bottom. The back seats are very accommodating and offer plenty of room. Large windows add to the airy feel and dispel any thoughts of claustrophobia.

Bugatti says the concept is still a work in progress, even though it looks great as a concept. As of now, the powerplant shares its 8.0-liter W-16 architecture with the Veyron, but the quad-turbo arrangement has been dropped in favor of twin superchargers. In addition, a new 8-speed transmission is expected to replace the 7-speed DSG. Final horsepower figures for the production vehicle have not been released, but Bugatti promises that when it arrives in the next few years, it will be the fastest and most powerful four-passenger sedan on the planet, as well as a well-designed machine.
