This is the Bugatti 16C Galibier. It is powered by an 8.0 liter 16-cylinder powerplant that is also featured on the super quick Bugatti Veyron. The huge engine has two-stage turbocharging and has the ability to run on biofuel and its power should be figured at about 900hp.
Rumor also has it that this almost production ready Bugatti shares the same platform with the Bentley Mulsanne. The company has released more images of the all-wheel-drive super saloon featuring a black Galibier. You can feast on these images after the jump.
