The extra power over the 1,184-hp Veyron Super Sport is generated via bigger turbochargers that form a sequential setup, referred to by Bugatti as “two-stage” turbocharging. Below 3,800 rpm, only two turbochargers are used. These are smaller and have very low spool-up times. Above the threshold, the two larger units come online. The result is said to be an “absolutely linear” power curve from 2,000 rpm. Additional power gains have come from a new titanium exhaust system that greatly reduces back pressure.
To handle all of the grunt, the Chiron features an all-wheel-drive system with a front-axle differential with integrated inter-axle lock and a rear-axle differential with integrated inter-wheel lock. Before reaching these, all the drive torque must go through a seven-speed dual-clutch transmission. This transmission has the largest, highest-performance clutch used on a passenger car.
All this sits within a new chassis that has a carbon fiber monocoque at its heart. The design is said to have rigidity comparable to an LMP1-spec endurance racer and features innovations such as the world’s first airbag capable of shooting through carbon fiber (used in the dashboard on the passenger side and in the seat housings), LED headlights and a driving modes selector. The outer skin of the Chiron is also made from carbon fiber.

In the cabin, the focus is on the driver and here, like the exterior, there is an air of elegance and minimalism. For example, in order to keep the central console as slim as possible and to allow a spacious impression, the climate control and infotainment systems have been separated. In front of the driver is a combination of digital and analog displays. The speedometer runs up to 500 km/h (310 mph)—something you don’t see every day.
Bugatti plans to build 500 Chirons, a total that likely includes all future variants of the car including a possible open-top version. Roughly one third of the production allocation is already accounted for, despite the car’s starting price of 2.4 million euros (approximately $2.61 million). The first examples are due to be delivered in the fall of this year.
“It is part of human nature to cross boundaries and set new records—to run 100 meters faster than ever before, to fly even further into space and to enter new realms,” Bugatti CEO Wolfgang Dürheimer said in a statement. “This striving is also our driving force at Bugatti.”
