The Chiron is far heavier than the Jesko . This means the Chiron's tires will experience more force than the Jesko 's at the same speed. Also, the Chiron likely will take longer to reach vmax (based on the 0-400-0 record vs the Regera). In a top speed run, Bugatti engineers have probably concluded that once their car reaches 318 mph, the risk of catastrophic failure becomes significant as a result of the total stress (basically = force x time) experienced by the Cup 2's. A 2020 Koenigsegg Jesko Absolut upgraded to empty Epic (purple) parts has 1098 PR and can't match the final PR wall of Day 7 with 1101 PR. You need additionally at least 3 PR to get past the last PR wall! The Senna and Bolide doors just use a single black friction pin placed at a 135 degree angle as the door hinge.
