Bugatti Chiron Super Sport Currently High-Speed Testing To Hit 273 mph

The Bugatti Chiron Super Sport is currently undergoing high-speed test drives to reach 273mph as part of its final development stage.

As part of the final stages of development, Bugatti is undertaking high-speed testing of the new Bugatti Chiron Super Sport to take it to speeds above 273mph.

Revealed earlier this month, the new Chiron Super Sport with its aerodynamically optimized bodywork is the latest member to join the Chiron family and is essentially the production version of the record-breaking Super Sport 300+ limited edition (only 30 units were made).

Conducted over several days of high-speed testing, Bugatti’s engineers fine-tuned the mechanics and variable settings of the Chiron Super Sport for the rear wing angle, vehicle height, damping, and electrically assisted steering lap after lap to determine the perfect setup ahead of customer deliveries later this year.

“Following successful road tests at up to 380 km/h, we are now refining the handling of the vehicle at up to 440 km/h to allow the Chiron Super Sport to perform with uncompromising safety, even at this incredible top speed, and give the driver a good, and above all, safe feeling at extremely high speeds,” explains Jachin Schwalbe, Head of Chassis Development at Bugatti. “Our engineers are from a wide variety of specialist backgrounds, enabling them to comprehensively verify our assessments, ensuring the best possible result and therefore maximum performance for the future owners while ensuring there is maximum testing safety.”

Bugatti has also modified the propulsion to ensure the Chiron Super Sport accelerates well in excess of 273mph. In the Chiron Super Sport, the 8.0-liter W16 engine delivers 1,176 kW/1,600 PS – exactly 100 PS more than in the Chiron thanks to larger turbochargers with more efficient compressor wheels. With the improved performance, the seven-gear dual-clutch transmission at full load and full speed now does not transition from sixth to seventh gear until 250mph. In addition, the Chiron Super Sport’s seventh gear ratio was made 3.6 percent longer.

“It’s crucial that the driver doesn’t notice the interruption in traction when changing gears at 7,100 rpm. We therefore set the boost pressure regulation more finely in the last three gears,” explains Bugatti Engine Application Developer Marco Schulte.

The Chiron Super Sport accelerates from 0 to 62mph in 2.4 seconds and to 124mph in 5.8 seconds, making it 0.3 seconds faster than a Chiron. When accelerating from 0 to 186mph – this takes 12.1 rather than 13.1 seconds, and the Chiron Super Sport accelerates from 0 to 248mph in 28.6 seconds, making it four seconds faster than the Chiron.

The Bugatti Chiron Super Sport starts at €3.2 million and will be included as part of the 500 Chiron to be created, so no specific limited numbers have been announced.
