(CNN) — Bugatti will sell its last purely petrol-powered supercar at auction in Paris on February 1, 2023. According to Bugatti, the car was not originally expected to be sold at all. The Bugatti Chiron Profile has been in development since late 2020 as one of several versions of Bugatti's flagship Chiron model. Bugatti always said only 500 Chirons would be built. The 500 includes several variants such as the Chiron Sport, Chiron Pur Sport and Chiron Super Sport, each with different top speeds, acceleration and cornering aggressiveness. (Bugatti also makes several other models, such as the Mistral and Divo, which share engineering with the Chiron but are considered separate models.) With a turbocharged 16-cylinder engine producing nearly 1,600 horsepower, the Chiron delivered phenomenal performance, while the Pure Sport featured more aggressive steering and suspension for even quicker acceleration. However, some customers were interested in a mixture of the two that offered purer sporting performance while offering a more mellow style. Bugatti engineers and designers have therefore set out to develop a new Chiron variant with pure sporting performance features, but with a more elegant and flowing design. The Profile features a larger grille and wider front air intakes than the base Chiron, bringing in more air to cool the big engine. The transmission was revised with shorter gear ratios to provide faster acceleration, allowing the engine to run to higher speeds. According to Bugatti, the Profilee is his Chriron model that accelerates the most. From 0 to 100 km/h (62 mph) in just 2.3 seconds, he can accelerate to 200 km/h (124 mph) in 5.5 seconds. Capable of reaching 236 miles per hour, the top speed is also faster than the Pur Sport, but not as high as other Bugatti models that reach 300 miles per hour, at least in theory. The name Profile is derived from his design of the elegant teardrop-shaped body used in the famous Bugatti cars of the 1930s. At one point, however, executives realized that all 500 Chiron models had already been ordered before the Profilee was available to customers. Nevertheless, they decided to complete this one that the engineers had been working on as a development model.The car is certified to drive legally on European roads, and now on sale. The French ultra-luxury car maker has previously indicated that the convertible W16 Mistral, unveiled last August, will be the company's last petrol model. Of these cars, only 99 of them are manufactured at a cost of at least $5 million per car. Bugatti's parent company Bugatti Mate, the chief executive of his Rimac, says Bugatti's next high-performance model will be a plug-in his hybrid powered by a different kind of gas his engine. I'm here. RM Sotheby's did not respond to questions about Profilee's estimate. Her Hagerty, who closely tracks the collector car's value and owns competing auction firm Broad Arrow, estimates it's worth $8 million to $6 million. However, the uniqueness of this car makes it difficult to judge its value. Because no car has ever been sold exactly like it before. Haggerty spokesman Jeremy Malcolm said in an email: "We need two aggressive bidders to get it that high.
