Form follows performance: New Chiron Super Sport – a reincarnation of the Bugatti design mantra

 

With the Chiron Super Sport, Bugatti is following the luxury car brand’s long-standing tradition of combining top speed with absolute luxury.

Bugatti will soon begin with the manufacture of the Chiron Super Sport in Molsheim, France. Delivery of the hyper sports cars with a price tag of 3.2 million euros (net) is scheduled to start early 2022.

Bugatti Chiron Super Sport has been designed without compromise for optimal aerodynamic performance. Bugatti engineers developed the new hyper sports car for top speed while fully embracing both luxury and comfort.

Bugatti developed a new luxury vehicle design with optimized aerodynamics for the Chiron Super Sport’s streamlined bodywork. The new Chiron Super Sport is an uncompromising reincarnation of the Bugatti design mantra, ‘form follows performance’. From the front splitter to the rear diffuser, every centimeter of its skin is designed for top speed.

At speeds over 420 km/h, a vehicle must offer sufficient downforce alongside minimal drag.

“Our aim was to give the vehicle a neutral setup at its top speed while also giving it as streamlined a shape as possible.” explains Frank Heyl, Deputy Design Director at Bugatti. The uplift forces exerted on the bodywork at 440 km/h are immense. The body of the Chiron Super Sport generates massive downforce to counter this uplift and perfectly balance the forces. “The design process was therefore in particular about achieving aerodynamic efficiency,” Heyl continues.

The Chiron Super Sport’s extended rear, which is known as a long tail, gives it new proportions and very distinctive aesthetics. An optional, new, horizontal color split visually extends the proportions of the Chiron Super Sport even further, making the hyper sports car appear even lower.

Bugatti thoroughly overhauled the 8.0-liter W16 engine for the Chiron Super Sport, boosting its performance by 100 PS to 1,176 kW/1,600 PS. At the same time, the vehicle weight was reduced by a further 23 kilograms. The engineers made modifications to the turbochargers, oil pump, and cylinder head with valve train, as well as to the transmission and clutch.

With the improved performance created by larger turbochargers with more efficient compressor wheels, the seven-gear dual-clutch transmission at full load and full speed transitions from sixth to seventh gear at 403 km/h. The Chiron Super Sport accelerates from 0 to 200 km/h in 5.8 seconds and to 300 km/h in 12.1 seconds. The Chiron Super Sport accelerates from 0 to 400 km/h seven percent quicker than a Chiron. Seventh gear boasts 3.6 percent longer transmission.

New chassis setup for top speed

Bugatti developed a new chassis specifically for the Chiron Super Sport’s high speeds and new aerodynamics. The steering systems and dampers create a firmer and more rigid connection to the vehicle from the driving feel, resulting in tighter steering for smoother steering movements. Harder springs stabilize the entire vehicle at top speed, and the engineers additionally also retuned the electronically controlled chassis. It regulates the settings in real-time in a matter of six milliseconds and adapts to the driving behavior. There is a choice of four driving modes – EB, Handling, Autobahn, and Top Speed.

With the extended rear and modified front, the Chiron Super Sport achieves balanced aerodynamics at top speed.

“Even on long bends taken at high speeds, the rear remains calm and neutral, resulting in a very composed drive in the Chiron Super Sport. Our focus at top speed is on absolute driving stability coupled with comfort,” explains Jachin Schwalbe, Head of Chassis Development at Bugatti.

This unwavering directional stability together with the quietness and rigidity of the steering and noticeably increased performance make the Chiron Super Sport unique.

Newly developed Michelin Pilot Sport Cup 2 tires which have been optimized for top speed offer greater rigidity and smoothness than grip-optimized tires fitted to the Chiron Pur Sport. What’s more, these are the only tires that can consistently drive at up to 500 km/h. ‘
