The Bugatti Chiron underwent an intense pre-production testing program. A major chunk of it was dedicated to extreme weather testing. Bugatti visited Death Valley in the US to test the new hypercar in the sweltering heat. The complete hot weather testing program has been documented in the following video.
Bugatti Chiron prototypes covered a total of 35,000 miles across the states of California, Nevada, Arizona and Colorado -- a journey which began in Los Angeles and culminated in Denver. The supercar performed flawlessly in the 125°F heat as the convoy passed through one of the driest and hottest places on Earth.
