Details surround the Galibier are beginning to surface. While it will share the same 8-liter W16 engine as the Veyron, it is rumored to be tuned down to just 800 horsepower.  The top speed will be limited to a paltry rediculously quick 220 MPH, making it the fastest 4-door saloon in the world. There is good reasoning for the Galibier to share the same chassis as the Bentley Mulsanne, so you can expect similar vehicle dimensions on the production version. Rumor has it that the 16C will hit the market with a $1.5 million dollar price tag.
