In 2019, the Bugatti Chiron Super sport 300+ came to be the an initial production car to drive 300 mph. This was virtually 15 year after the Bugatti Veyron ended up being the an initial to reach 250 mph. We discover why it take it them so lengthy to with this benchmark and also what automakers prefer Bugatti have actually been law to follow it. Following is a transcript the the video.
You are watching: Car that can go 300 mph
Narrator: In 1987, the Ferrari F40 came to be the first street-legal vehicle to go 200 miles every hour. In 2005, Bugatti"s Veyron hypercar damaged the 250-mile-per-hour barrier. In so late 2019, The Bugatti Chiron super Sport became the first production automobile to ever reach 300 miles every hour. Yet why has actually it taken virtually 15 years simply to walk 50 miles per hour faster?
Andy Wallace: girlfriend think around speed together a linear measurement. And also I suppose it need to be come a human being brain. But if you"ve ever gone 150 miles an hour prior to anywhere, if girlfriend then step that up simply to 180, it"s only 20%, but the distinction is huge.
Narrator: That"s Andy Wallace, the driver behind Bugatti"s 300-mile-per-hour run.
Andy: Aerodynamically, downforce, lift, drag, it"s all increasing significantly as a square the the speed. If for instance you had actually a vehicle that was qualified of 270 mile an hour, the performance you have to take the same auto up to 280 is nice massive.
Narrator: The power required to get rid of a pressure like drag, or waiting resistance, is most intimidating. The pressure required to push things through the atmosphere increases in ~ the cube the velocity. To translate, a auto that requirements 200 speech to conquer aerodynamic traction at 150 miles per hour, would require 1,600 horsepower, or eight times together much, to with 300 miles every hour. But to construct a 300-mile-per-hour car, it"s no as straightforward as a monstrous engine. First, you have to start through the tires.
While they"re not the most complicated car part, as the only part that touch the road, tires are one of the many important. And also at 300 miles every hour, as soon as a puncture or blowout can end in disaster, they average everything. At that sort of speed, the Bugatti"s tires, turn 68 times per second, had actually to stand up to 7 loads of tearing force trying to rip castle apart. Because that an idea of just just how intense the is, the tires ~ above a Porsche 911 driving full speed just experience around 3.
Andy: among the points you have to do is you should stop the tires from changing shape due to the fact that these massive tearing forces would in reality make the tires crowned ~ above the top. The tires were not entirely different, very same carcass, exact same molding, as the traditional Chiron tire. Yet what they did execute is reinforce the very last steel band that goes top top the tire prior to the rubber go on. I think the tricky part was castle didn"t desire to rise the weight of the tire.
Narrator: To do this, Bugatti chose every engineer"s favorite weight-saving material: carbon fiber. It have the right to be 10 times more powerful than steel yet five times as light. After adding a thick layer top top the tire"s carcass, the layer of rubber listed below the tread that"s responsible for soaking up shock, Bugatti"s designers had to test it. Come make certain the tire might handle 300 miles every hour, they lugged it come Michelin"s plane test center in north Carolina. Using the exact same test bench used by companies like NASA, they discovered that it might handle as much as 318 miles every hour prior to warping.
But also the strongest tire method nothing there is no the strength to rotate them. For an idea that just exactly how much power is needed, look at no further than among Bugatti"s biggest rivals in the gyeongju to 300 miles per hour, Hennessey. The company"s upcoming gift F5, estimated to reach 301 miles per hour, residences a 6.6-liter V-8 that provides an astounding 1,817 horsepower.
To generate an ext horsepower, an engine has to burn much more gasoline which requires much more air. Among the most common ways to feed much more air right into the engine is v turbochargers. The venom F5 not only uses massive twin-turbochargers, yet it additionally manages to reach a very high RPM. RPM stands for changes per minute, and also it steps how fast the engine is spinning. In general, the faster an engines spins, the much faster it burns air and also gas, and as a result, the more power the makes. A smaller sized engine through smaller and also lighter parts deserve to spin much faster with more efficiency, yet has potential to wear out much faster from the rate than a larger engine v a lower RPM. All of this needs to be taken into factor to consider when selecting an engine for speed records.
But in the end, the biggest obstacle come 300 miles per hour is air. The drag, or air resistance, that a automobile encounters as it viewpoints this speed, can be contrasted to what you encounter as soon as swimming.
Christian Von Koenigsegg: The resistance increases in square. So going indigenous 200 come 300 is basically, approximately calculated, twin the power that you"re running into. At around 200 miles per hour, you get an ext into airplane aerodynamics where you"re in reality compressing the air in former of the vehicle, and also it takes various routes over the bodywork 보다 at slow speeds.
Narrator: That"s why the goal of engineers when developing a hypercar"s body is to get rid of as much drag as possible. No vehicle does this far better than automaker Koenigsegg"s upcoming Jesko Absolut. Based upon the company"s Jesko hypercar, the Absolut is approximated to reach as much as 330 miles every hour. Comparable to Bugatti"s record-breaking Chiron, it has a much longer flattened tail. This makes sure waiting flows off the car"s rear seamlessly. Without it, you have a greater chance the separation in the airflow, which would only add to the drag.
The car additionally improves other forms of resistance. The standard Jesko features a substantial rear wing to boost downforce because that those tight corners ~ above the track. However downforce ~ above the behind wing of a 300-mile-per-hour automobile would just slow points down. Ditching the tail reduced the Jesko Absolut"s preferably downforce from end 3,000 pounds to simply 330.
To store the Jesko Absolut indigenous flying turn off the sides of the test strip, that huge rear wing was changed by two little tail fins. They may look tiny, yet they redirect the vortex that air created behind a speeding car that create turbulence. And also those sharply reduced side vents do an ext than just cool the engine.
Christian: they act choose kind of tiny side parachutes. Lock actually end up being kind of totally efficient at end 200 miles per hour. And also the reason for that, if they worked better at reduced speed, they would be also restrictive at higher speed. They would be blocking too much.

Narrator: yet as superior as this automakers" innovations have been, no one of it would be feasible without the means testing has actually advanced. One aerodynamic simulation the took a week to operation 10 years ago can now be done in three or 4 hours, allowing new solutions come be tested immediately. And while Bugatti may have currently been the first to with 300 miles per hour, automakers room constantly chasing the next record.
