Bugatti’s ultra-luxury Galibier sedan concept was first shown to the public in the fall of 2009. Initial customer feedback was somewhat underwhelming, and potential buyers criticized the car as not being special enough, both inside and out.

Given the Galibier’s intended positioning and price, Bugatti opted to take customer feedback to heart, and a redesign was begun. Then came a management change at Bugatti, with Franz-Josef Paefgen replaced by Wolfgang Duerheimer as head of the Bugatti and Bentley brands.

Motor Trend says that Duerheimer was also dissatisfied with the Galibier concept, and insisted on additional design and engineering changes. That put the halo car’s debut on indefinite hold, despite its potential for larger sales numbers than the Veyron.

Fast forward to 2012: Bugatti has undergone yet another change in leadership, leading to another likely delay in the Galibier project. This time, Duerheimer is out (gone to head Audi’s R&D), replaced by Wolfgang Schreiber. As was the case when Duerheimer took over, it’s likely that Schreiber will want changes to the the Galibier as well.

If there’s good news in the change at the top, it’s this: Schreiber was the executive  brought in when transmission problems postponed the launch of the Veyron. Schreiber soon took over the final development of the Veyron, so it’s clear that he knows a thing or two about getting automotive launches back on track.

For now, the only thing certain about Bugatti’s upcoming sedan is this: when it hits the market (likely before the rumored hybrid successor to the current Veyron), it will be fast, it will be luxurious and it will be very, very expensive.
