By the end of 2012, Bugatti will cease production of its Veyron coupes (after a production run of 300 cars) and Veyron Grand Sport convertibles (no more than 150 cars). But the French manufacturer’s renaissance is far from over. Unveiled in September to a select group of industry insiders and potential customers at Bugatti’s Molsheim headquarters, the sleek four-door Bugatti 16 C Galibier Concept (www.bugatti.com) is one of three concept cars the company plans to introduce by late 2010. The Galibier carries design traits from the Veyron, but the sedan’s mechanics are largely new. Its 8-liter W-16 engine—which can run on ethanol—sits in the front of the car and incorporates a two-stage supercharger (instead of the twin turbochargers of the Veyron) for additional power.
