Bugatti Chiron Super Sport produces 1,596 hp on the dyno

Bugatti recently strapped its Chiron to a dynamometer and the results put to rest any doubts of the horsepower ratings of the company’s hypercars.

The particular version used in the test is the Chiron Super Sport, whose official output is 1,578 hp, or 1,600 ps in the metric horsepower figures Bugatti uses.

Following the dyno run, Bugatti registered a peak output from the car’s 8.0-liter quad-turbocharged W-16 engine of 1,618 ps, which translates to 1,596 hp, or 18 hp more than the car’s official rating.

The output at the wheels was measured at 1,301 ps, which is equivalent to 1,282 hp. The parasitic losses of the drivetrain here measure close to 20%, which is high but not unreasonable for a car with a complex transmission and all-wheel-drive system like the Chiron Super Sport.

Dyno tests are notorious for producing results which can vary based on a number of factors including the design of the dyno itself, which is why we’ve seen higher results achieved from regular Chirons during dyno testing. To achieve results close to what owners can expect in the real world, Bugatti used a special type of dyno designed for high-performance cars with all-wheel drive.

Here, each wheel sits on one large roller instead of between two small rollers like on most dynos. According to Bugatti, because each wheel has only one touchpoint, which is the case when a car is driving on a road surface, the results are more accurate.
