0-60 is blitzed by the Chiron in just 2.5 seconds to the rear-wheel drive Regera’s 2.8 second 0-62 mph run. The Chiron still has a hair’s edge to 125 mph, taking just 6.5 seconds to the Regera’s 6.6-second charge to 124 mph. Suddenly, the Koenigsegg digs in, beginning to strut away from the Frenchie toward 186 mph. Koenigsegg claims a 10.9 second 0-186 mph sprint compared to the Bugatti’s 13.6 second run. Oh boy.
