In order to build the world's most capable supercars, Bugatti understands the need for balance between brakes and acceleration. Everyone knows they build fast cars, but what good is speed if you can't stop? Working along with the active rear spoiler, the Chiron's massive 16.5" carbon brake rotors are controlled by titanium pistons. To put them to work, Juan-Pablo Montoya was hired for an unprecedented show of force.
A new Chiron was equipped with GPS-based telemetry from VBOX Automotive, and JP was given the Top-Speed Key. In a weekend of high-speed testing, he surpassed his personal speed record. As an Indycar champion, his previous record was 252 mph, and the Chiron took him to 260. The event culminated in a run from 0 to 400 km/h (249 mph) and slamming on the brakes. The Chiron uses four turbos like its predecessor, but the system is now sequential. Launch control spins up the smaller ones at 2,800 rpm to enable a smooth holeshot. Above 3,000 rpm, the larger ones come alive to reach 400 km/h (249 mph) in only 32.6 seconds. In less than 10 seconds after, the car was standing still. Bugatti now holds the 0-400 km/h-0 record at 41.96 seconds. The run was just under 2 miles long, and it prompted the driver to say: "The Chiron is so incredibly fast it takes your breath away. And its braking is at least as impressive. And the car is just so stable and consistent. I feel honored to be part of this project.”
