VW insiders have confirmed the group’s Bugatti division will sign off the four-door Galibier supercar as the Veyron’s replacement come 2013.Teased to (extremely) well-heeled Bugatti Veyron owners since late last year at the company's Molsheim headquarters, the (ostensibly) conceptual Galibier always seemed to feature way too many production design details for our liking. Now, as we expected, it will go into production to continue the Bugatti brand’s cachet beyond the fabled Veyron – which ceases production in 2012. The exquisitely styled (and detailed) four-door supercar will be limited to a total production run of only 300 units and priced at around £900 000.Two blowers instead of four turbosPowered by a detuned version of the Veyron’s 8l W16 engine, Galibier’s estimated 600kW power peak is boosted by twin superchargers instead of the Veyron’s quad turbo set-up. Industry insiders expect the Galibier to be the first production four-door to dip under three seconds for the benchmark 0-100km/h sprint before powering on to a 386km/h top speed. Sporting two sets of quad exhausts (eight pipe ends in total) the 16C Galibier brooks no argument as to its performance capabilities.For those Bugatti acolytes who yearned after a four-door alternative since the glorious (and tragic) EB112 four-door was unveiled in 1993. It has been a long time coming, yet the prospect of a four-door Bugatti finally going into production is a moment to savour for aristocratic petrolheads. Ettore would surely have approved.
