The Bugatti Chiron Super Sport recently shattered expectations on a dynamometer, revealing far more power than its already impressive official rating. In a YouTube video on The Hamilton Collection channel, owner Steve Hamilton set out to verify if his Chiron Super Sport truly delivered the claimed 1600 horsepower from its 8.0-liter W16 quad-turbo engine. The results surprised even seasoned hypercar enthusiasts.
From the first dyno pass, it was clear that Bugatti’s power figures might be conservative. The Chiron Super Sport registered 1442 hp at the wheels, which, after accounting for the estimated 14% transmission loss, translates to approximately 1675 hp at the crank—75 hp more than Bugatti’s advertised number. However, Hamilton took it a step further, engaging the Chiron’s special key that unlocks “top speed mode,” which pushes the W16 to its absolute peak output. This mode increased the wheel horsepower to 1457, resulting in an adjusted 1692 hp at the crank.
For the final dyno pull, the Chiron Super Sport was run in 4th gear instead of 3rd. The results were staggering: 1492 hp and 1232 lb-ft of torque at the wheels, translating to a jaw-dropping 1734 hp at the crank—an increase of 134 hp over Bugatti’s claimed output. This test suggests that the Chiron Super Sport not only surpasses the base Chiron’s output by over 200 hp but also confirms its standing among the most powerful production cars in the world.
These figures are a testament to Bugatti’s engineering prowess, indicating the W16 engine is capable of even more than initially disclosed. For hypercar fans and horsepower enthusiasts alike, this dyno test highlights the Chiron Super Sport’s unmatched combination of luxury, speed, and raw power.
