Ah, the Chiron Sport. The track-focused hypercar is as fast and delicious as a normal Chiron but Bugatti gave it a substantial weight loss and enhanced performance on corners. Though it's mechanically identical to the Chiron, harnessing a quad-turbocharged 8.0-litre W16 engine that produces 1,500 bhp and 1,180 lb-ft of torque, the Chiron Sport is more expensive with a £320,000 premium over a standard Chiron.

With this amount of power, one can only imagine how's it like to push the French hypercar to its top speed.

Top Gear, however, was able to get access to a Bugatti Chiron Sport and did an actual top speed run on Volkswagen's Ehra-Lessein testing facility. The private tarmac features a high-speed circuit with 5.4 miles worth of straight road, well enough to allow the Chiron Sport to reach its theoretical top speed of 261 miles per hour.

As Top Gear puts it, the top speed figure is theoretical because nobody outside of Bugatti has ever hit the mentioned numbers above. Also, it's important to note that it isn't only theoretical but electronically-limited as well. 

Of note, the Top Gear's top speed run with the Chiron Sport isn't as sensational as some may have hoped it would be. The Veyron has set a record at 268 mph, while the Koenigsegg Agera RS was able to do reach 278 mph on a closed Nevada highway. Bugatti's holding off on its own unrestricted run because it's still waiting for the right tyres to use.

While Top Gear's run is a little over the theoretical top speed at 263 mph, it's still a bit short in beating the Veyron and the Agera RS. Can Bugatti do an unrestricted top speed run already?
