The Bugatti Tourbillon is a mid-engine hybrid sports car manufactured by French automobile manufacturer Bugatti. The Tourbillon succeeds the Chiron and is limited to 250 units.[3] It was unveiled in an online live stream on 20 June 2024.[4] It is priced at €3.8 million (US$4.1 million).[5]
The car is named after the tourbillon, a mechanism used in certain high end mechanical watches to increase their accuracy.[6]
Bugatti states that the Tourbillon is a completely new design,[7]
The interior of the Tourbillon features a fully analog instrument cluster operated by mechanical gears and designed to look like a watch movement, with the speedometer and tachometer needles arranged to resemble an hour and minute hand. It also features a steering wheel with a fixed central hub where only the outer rim rotates, allowing the instrument cluster to remain visible at all times. Unlike past Bugatti models, the Tourbillon features a center infotainment screen, which retracts into the dashboard when not in use. Bugatti says that, like in past models, their goal was to make sure that the car remains "timeless", even when the screen technology becomes outdated. The center panel of the Tourbillon is made from machined aluminum and machined crystal glass, while the watch-inspired instrument cluster is made from titanium by Swiss watchmaker Concepto.[9]
The Tourbillon is powered by a naturally aspirated undefined cc V16 engine. The engine, developed by Cosworth, has a bore × stroke of 92x78.55 mm and is implemented in conjunction with 3 electric motors, 2 located at the front axle and 1 at the rear. The engine has a power output of 1000 PS and 900 Nm of torque, while the electric motors have a combined power output of 800 PS, making for a total of 1800 PS. Bugatti says that the choice to replace the quad turbocharger setup of the Chiron with a naturally aspirated engine was to make the experience "more emotional" and allow for a higher rev count, with the engine redlining at 9,000 rpm. The V16 features a crossplane crank design, a 90-degree bank angle, and dry sump lubrication system. The engine weighs a total of 252 kg.[10] The Tourbillon uses an 8-speed dual-clutch transmission mounted longitudinally at the rear of the engine, in contrast to the Chiron where it was mounted at the front.[8] The battery is a 24.8 kWh unit mounted in front of the engine in the central tunnel, which allows for a complete electric range of around 60 km.
For the suspension of the Tourbillon, Bugatti collaborated with Divergent Technologies, the parent company of Czinger, to create organically shaped 3D-printed suspension components designed with the assistance of AI. The suspension is a forged aluminum multi-link setup that Bugatti says is 45 percent lighter than the suspension system found in the Chiron.[4]
The chassis of the Tourbillon is made from T800 carbon composite, with front and rear frames that use 3D printed braces, and a battery that is integrated into the monocoque in order to save weight. It also features a diffuser designed to serve as part of the crash structure in place of a rear crash beam, which functions as another weight-saving measure.[11][12]
Bugatti says they expect the Tourbillon will be able to accelerate from 0–100 km/h in under 2.0 seconds, 0–200 km/h in under 5.0 seconds, 0–300 km/h in under 10.0 seconds and 0–400 km/h in under 25.0 seconds. It has an estimated top speed of 445 km/h with the use of a speed key, and is limited to 380 km/h without it.[13]
