You will never be able to use a car that can hit 300 km / h on public roads, and it would be so wildly dangerous to try that I would hope that you would go to prison right away (if you survived). But that does not mean that it is still not cool to see the record record of the Bugatti Chiron, even if the plate is broken by an EV built in China that no one reads this will probably ever see on the road, let alone get the chance to drive. I mean, it is not every day that a new car is crowned the fastest car in the world, even if Yangwang is only planning to build 30 examples.
In August the U9 293.54 MPH, but that was only the track edition. Only a few weeks later the Yangwang U9 Xtreme struck 308 km / h, making it the official street-legal production car ever built. That must be pretty exciting for young car enthusiasts, but do you know who else is enthusiastic? Engineers, including our favorite engineer who became YouTuber, explained Jason Fenske or Engineering. And with a new record set, you better believe that it is time to break out the whiteboard, to open some dry erasemarks and talk figures.
As Jason notes, with 2,977 hp, the U9 Xtreme is easily the most powerful production car ever, and with engines that can hit 30,000 rpm, it also has the fastest spinning engines that are ever used in a production car. In addition, the 1,200-volt system makes it the highest voltage production vehicle ever, and it also offers the fastest discharge speed of the battery at 30 ° C. However, the question is, with sufficient space to run, how much faster could the U9 Xtreme actually go, and can it hit 400 mph?
Faster than 400 mph … theoretical
Unfortunately for everyone who hopes to see Jason calculate the only real top speed of the U9 Xtreme, there are a few too many variables here to get more than a rough estimate. Yet it is not as if he is assuming here that a spherical cow is taking. Connect a rough estimate of the U9 Xtreme towing coefficient in the formula, and a bit Back-of-the-Napkin Front-of-the-Whiteboard-Wiemology brings us to a theoretical top speed of 415 MPH. That’s pretty fast.
However, that is based on a resistance coefficient of 0.24. If the drag is as high as 0.3, the same formula says that you will be short of 400 mph after a topping at only 385 mph. On the other hand, if it is even more aerodynamic than initially assumed, a towing coefficient of 0.2 theoretically the U9 Xtreme would give a top speed of 440 mph. Despite the fact that I spent four years at Georgia Tech, I have never followed an engineering course, so I can’t tell you which is more accurate, but I can still send an e -mail, so hopefully their PR representative will return with an official drag -coefficient.
Does this mean that we will see Yangwang shooting for 400 mph next month? Probably not. As Jason notes, perhaps the biggest limitation of a real-world test such as this space. Where on earth are you going to take the U9 Xtreme to test the actual top speed? Moreover, you also need tires that you can safely use with speeds well above 400 km / h that are also legally legal, and Michelin does not exactly have a set that they can pick up at Costco. And can the battery actually turn off enough power to get the car past 400 km / h? Does it have the necessary cooling? Heck, does it even have the gear to cross 400 km / h?
From there, the video even becomes even nart (in the best possible way, I promise), so instead of reading my words, why wouldn’t you give everything a watch?
