Bugatti will build neither a ‘SuperVeyron’ to top the 1183bhp SuperSport, nor a production version of the 2009 Galibier concept, company boss Dr Wolfgang Schreiber has exclusively revealed to Top Gear.

Despite rumours of a yet-more-powerful, yet-faster Veyron to send the epochal hypercar into retirement with a bang, Dr Schreiber reckons 268mph is, quite frankly, enough.

“We will not produce a ‘SuperVeyron’ or Veyron Plus, definitely,” said the Bugatti president, who was key in the development of the Veyron back in the early Noughties as Bugatti’s Technical Director. “There will be no more power. 1200PS is enough for the chapter of Veyron and its derivatives.”

Sounds pretty definitive to us. And Schreiber is equally clear about the fate of the opulent Galibier fastback, explaining it would dilute the Bugatti philosophy.

“We have talked many, many times about the Galibier, but this car will not come because […] it would confuse our customers. With the Veyron, we placed Bugatti on top of all super-sportscar brands in the whole world. Everyone knows that Bugatti is the ultimate super sportscar. It’s easier for current owners, and others who are interested, to understand if we do something similar to the Veyron [next]. And that is what we will do. There will not be a four-door Bugatti.”

So the next Bugatti will follow firmly in the footsteps of the current Veyron. But, of course, the current hyper-thing battlefield is very different from that which greeted the original. In the last year, McLaren’s P1 and the Porsche 918 have - without pitching for the Veyron’s production speed crown - pushed the hypercar handling envelope, with the LaFerrari soon to join the fray, too.

So what’s the brief for the next Veyron? Forget McLaren, Porsche and Ferrari, says Dr Schreiber. All the next Veyron has to worry about is… the current one. “It has to redefine the benchmarks,” he states firmly, “and the benchmark today is still the current Veyron. We are already working on it.”

Will the Veyron, like the McLaren, Porsche and Ferrari, utilise hybrid power in pursuit of ultimate speed?

“Maybe,” smiles Dr Schreiber. “But it’s too early to open the door and show you what we have planned. For now we have to keep the focus on the current Veyron, and help people to understand that this really is the last opportunity to get the car, which will have run for ten years from 2005-2015. Then we will close this chapter and open another one.”

Dr Schreiber confirmed that just 43 of the Veyron’s total 450-car production run remain up for grabs, including the remaining three of Bugatti’s six-strong ‘Legends’ series. “The 300 coupés have sold out. We announced we would only make 150 roadsters, and we only have 43 left. People are becoming increasingly conscious that their opportunity to buy a Veyron is running out…”
