The Bugatti Chiron is finally set on a dynamo.

The Bugatti Chiron is a collection of impressive specifications, including 1,480 hp and 1,180 lb-ft of torque from its factory 8.0-liter W-16 quad-turbo engine. To verify these numbers, Cannonball Garage in Gilbert, Illinois, put the Chiron on the dyno.

The test car was provided by The Hamilton Collection, and this is the first time the Chiron has been dyno tested outside of the Bugatti factory; a video from The Hamilton Collection's YouTube channel shows why. To secure the Shillon on the dyno, Cannonball Garage first had to remove the undertray that stabilizes the Shillon at speed. Once on the dyno, there was little room for the car's wide tires, which struggled unnervingly with each pull.

The result was 1,369 hp at the wheels and 1,163 lb-ft of torque at 6,620 and 5,060 rpm, respectively. The dyno used 93 octane gasoline. The official Bugatti figures appear to be accurate, given that the output measured at the wheels is lower than that measured at the crank due to losses in the drivetrain.

When the Chiron is unleashed on the track, it can go from a standstill to 248.548 mph (400 km/h) in 41.96 seconds and back from a stop.

However, this is just the standard Chiron. Bugatti is steadily introducing new versions, including the 1,577-horsepower Chiron Supersport 300+, a production version of the prototype Chiron that broke the 300-mph barrier in 2019. The production model differs slightly from the prototype in that its top speed is electronically limited for safety reasons. Bugatti has not publicly stated that limit.

Production of the Chiron is coming to an end; as of October 2021, only 40 of the total 500 cars produced remain. The last Syrons will be the Pur Sport and Super Sport models. The Pur Sport is a more handling-focused version, while the Super Sport is essentially a Super Sport 300+ with more luxurious equipment, a more forgiving chassis, and a lower top speed.
