Last week, Bugatti surprised us when it unveiled the new Chiron Super Sport just a few days after the final version of the La Voiture Noire was revealed. With a top speed of 273 mph, its performance is on par with the phenomenal Super Sport 300+. But as impressive as it is, the Chiron Super Sport is not the most extreme car Bugatti has ever made - that would be the Bolide.

Revealed last year, the Bugatti Bolide is a one-off, track-only monster with an innovative aerodynamic design and astonishing performance. Billed as Bugatti's "lightest, fastest, and most track-focused concept yet," the Bolide made a rare public appearance at the Milano Monza Motor Show, allowing us to see it in the metal for the first time.

In real life, the Bolide's aerodynamic design looks even more mesmerizing, with every design element serving a functional purpose. Aggressive air intakes and a prominent splitter dominate the front end, but the Bolide looks even better at the back with its active rear wing that looks like it belongs on a Le Mans racing car and distinctive X-shaped taillights inspired by a fighter jet that look like an X-wing starfighter when lit up. Then there's the extraordinary sound.

As the Bolide is loaded onto a truck, we get to hear its 8.0-liter W16 engine start-up for the first time, and it sounds biblical. Since the Bolide isn't road legal, the exhaust doesn't need to meet noise regulations.

It's so ear-shatteringly loud you can see several people in the crowd jump as it starts up and roars into life. What you're hearing is the sound of the same 8.0-liter W16 that powers the Chiron cranked up to 1,824 hp and 1,364 lb-ft of torque, up from 1,479 hp and 1,180 lb-ft in the standard Chiron.

The sprint from 0-60 mph takes just 2.17 seconds before the Bolide maxes out at over 310 mph based on Bugatti's simulation tests. During the show, crowds were also treated to the Bolide's first dynamic appearance as it was paraded around the streets.
