To go 300 mph it takes a lot.
It was not easy to create a Bugatti CHiron capable at 304 mph. The base Chiron is a powerful car, but Bugatti had to redesign many parts of the vehicle to reach this record-setting speed. It took Bugatti a lot of work to modify the standard Chiron design to build the Chiron Super Sport 300+. Here’s a list of all the new and changed components. This is a testament to the lengths that hypercar manufacturers must go to break new speed records.
The leap from a normal Chiron to ChironSuper Sport 300+ was almost as large as that between Veyron and Chiron in 2016. Bugatti spent considerable time improving the aerodynamics of the Chiron Super Sport 300+.
Bugatti then turned their attention towards the rear of the car, after the front aero was modified to make it perfect for speeds exceeding 300 mph. The Chiron Super Sport 300+’s back end is 25.0-centimeters wider than a regular Chiron. This helps to control downforces as well as lift at the rear, allowing for a small breakaway.
The engine now features a 3-D printed titanium exhaust and larger, more efficient turbochargers. The final output is 1,587 horsepower and 1,180 pounds of torque. Bugatti states that all four turbos now use a compressor wheels that increased in size from 74 millimeters to 77 millimeters to enable higher throughput. To be able provide more compressor power and increase boost pressure, the turbine wheel was enlarged from 64.4 to 67.2millimeters in size.
The Chiron Super Sport 300+ represents engineering excellence. We are excited to see what Bugatti does next.
