A rev limit of 7,000 rpm is higher by 200 than that of the regular Chiron. Furthermore, the quad-turbocharged W16 engine found under the Pur Sport’s engine cover makes its maximum 1,500 horsepower (1,103 kilowatts) between 6,700 and 6,900 rpm, a wider peak by 200 rpm. The altered redline matches the shorter gear ratios of the Pur Sport better, providing optimized shift points that reduce power interruptions on upshifts.
