Bugatti has kicked off circuit testing their newest addition, the Chiron Pur Sport, beginning with a run at Bilster Berg. The engine remains the same 8.0-liter quad-turbo W16 that makes 1,500 PS (1,103 kW / 1,479 HP), but the redline has moved 200 rpm higher than on the “regular” Chiron, reaching 6,900 rpm now.
