Top Speed of 440 km/h
Long-tail design can run at top speed with more stability
Bugatti has just launched the Chiron Super Sport. A long-tail variant of the Chiron that looks a lot like the already existing Super Sport 300+ that the automaker used to top 300 mph back in 2019. This one is set to hit a top speed of 440 km/h, the same as the SS 300+ that came before.
“The Chiron Super Sport stands for increased comfort and elegance coupled with even greater performance and higher speeds,” said company CEO Stephan Winkelmann, calling it “another distinct personality” in the Chiron line.
The aim was to make the car more capable of reaching and sustaining its electronically-limited top speed. Bugatti said that once 420 km/h is reached, the car needs not just reduced drag but also enough downforce to keep it stable and planted to the asphalt. As speed rises, the wing shape profile of a car leads to “immense” uplift forces the company says.
So they’ve lengthened the rear by 25 cm to hold the air to the bodywork for as long as possible. The diffuser is larger and reprofiled to slash the rear trailing surface. These changes cut slipstream and wind resistance, helping it to achieve a high top speed.
The Bugatti Chiron Super Sport’s new diffuser also lets the car retract the wing for top speed without worrying about sticking to the pavement. To let the air out of the wheel arches, Bugatti has copied the EB 110 Super Sport’s nine air holes to balance the load.
The 8.0L quad-turbo W16 has new turbos, oil pump, and cylinder heads that can let it rev 300 rpm higher and widen the torque band. 100 hp extra is on tap for a total of 1,577 letting the car hit 200 km/h in just 5.8 seconds and 300 in 12.1. It’s seven percent quicker to 400 km/h than a standard Chiron.
Stiffer springs and new dampers stabilise the car at speed with new Michelin tires capable of 500 km/h that are tested on the bench originally designed for space shuttle tires and are x-rayed before being leaving the factory.
How to tell this apart from lesser Chirons? The exhaust exits have been split up and are now much further apart at the back. Bugatti says that makes it “unmistakable,” even from far away.
The car starts from 3.2 million euro (CAD 4.7m) and deliveries are expected to start next year.
