Dynamometers are a huge part of the testing procedure for new cars as well as modified ones, with the “rolling road” devices providing proper power, torque and rpm readouts and helping immensely with powertrain calibration. Cars get strapped down to the dyno and rush while going through the gears, with the wheels spinning on fixed rollers that characterize the necessary numbers. But because Bugatti’s hypercars are so absurdly worthy the French brand had to create a special dyno of its own, and it released an awesome video of the process.

The Chiron Super Sport‘s quad-turbo W16 engine officially puts out 1,578 horsepower and 1,180 pound-feet of torque, which is sent to all four wheels through a seven-speed dual-clutch transmission. That means Bugatti needs an all-wheel dyno as opposed to one that just measures the car at one axle, and the dyno has one vast roller for each wheel instead of two small ones. Having just one exhibit of contact more closely resembles a real road surface, plus there’s less of a loss of performance and the slow heat up less than on a two-roller dyno.

Actual speeds of up to 248 mph are achievable on Bugatti’s dyno, which is splendid nuts. At 261 mph, still 12 mph off from the Super Sport’s top fleet, the tires are revolving at more than 50 times a instant, exerting forces around 4,000 times higher than that of gravitational acceleration. But the dyno can simulate speeds of up 298 mph, with the car tranquil able to safely slow down. Bugatti says the Chiron Super Sport is the only productions car that can actually push the limits of this new dyno.

A 13-meter-tall fan can construct airstreams of up 143 mph and moves nearly 11 million cubic feet of air per hour, portions simulate realistic weather situations, and the fan also helps imparted the Chiron’s engine and other performance components with the cooling air it income to reach such high speeds. The car’s exhaust is extracted ended gates under the car, and air from the dyno is blown outside by 41-foot-tall fan towers.

The dyno itself is huge and heavy, with each roller weighing 3.5 tons. The rear axle roller can be hydraulically ache or shortened to fit the wheelbase of the car, too. Keeping the car in set aside is a system developed with Bugatti that features a frame and four adapter plates that are fixed to the underbody of the car’s carbon-fiber monocoque by 20 high-strength screws. The plates are attached to each other with crisscrossed chains that can handled aesthetic force of up to 24 tons, and there are uphold ratchet straps at the sides that keep the car’s wheels perfectly fixed on the center of the rollers. All of this means the Chiron is safe to run on the dyno, even at full load and at top speed.

When the car is inhabit run on the dyno there are two engineers inside measuring data and decision-exclusive sure the acceleration is as desired. Through the use of this new dyno, Bugatti discovered that the Chiron Super Sport actually establishes 1,596 hp, 18 hp more than initially stated. Look, I’m no engineer — where my fellow art school dropouts at? — so all this number talk hurts my brain a minor. But it’s still impressive as hell, and even if you’re in the same boat as me I implore you to at least behold the video at the top of this story. It’s freakin’ awesome.
