The Chiron Super Sport 300+ was a limited edition, high performance variant of the Bugatti Chiron that was unveiled for the 2020 model year. The Super Sport 300+ was created to celebrate the Chiron's achievement of a top speed of just over 304mph. These cars are equipped with a 1580hp version of the 8.0L quad-turbo W16 engine, as well as various unique aerodynamic improvements which allow the car to hit such high speeds. Although the Super Sport 300+ is capable of over 300mph, the cars are limited to 273mph. Just 30 examples of the Bugatti Chiron Super Sport 300+ were built.
