Bugatti's Giant V16 Engine Is Insane - All The Tourbillon Details!

The Bugatti Tourbillon Packs A Glorious 1,000 HP V16 Engine.

The wraps are off the new Bugatti Tourbillon, and it's rather incredible. 1,800 horsepower is delivered through the combination of an 8.3L naturally aspirated V16 engine, as well as three electric motors. Two up front, with one in the back, and ability to run ICE-only, meaning a 1,000 HP naturally aspirated RWD experience. In this video we'll cover four main topics:
1) What are the specifications of the new Bugatti Tourbillon?
2) Why did Bugatti choose to go naturally aspirated?
3) Why did Bugatti choose a V16 over their W16 engine?
4) What is the Tourbillon's top speed?

While the Tourbillon is limited to 445 km/h, it's capable of more. But how much more? Is 500 km/h possible? We'll discuss!

Hey Jason, love your videos. You’ve done a good job here. But just one little thing you have missed here. The Nevera does NOT drop in power because of battery derating nor is it overheating. If I remember correctly, it might have reached 35 °C in that run, which is very far from the maximum temperature. The power drops because the motors are reaching their maximum speed due to the transmission ratio. As you well know, with single speed gearboxes like in Nevera, there is a trade off between acceleration and top speed. We figured that 412 km/h was plenty and did not want to compromise on acceleration. So basically, the battery could deliver 1.4 MW for a lot longer if the powertrain could take it (longer ratio). The drop in power is due to the motor power curves which drop off at the end of the RPM range and the car reaching its equilibrium speed at max RPM.

As for the Tourbillon top speed - as you said… Let’s see 🤓

Would love to geek out on some other stuff you’re talking about here.

Limiter at 445km/h is something mental

"if there's one thing dudes love more than watches, is being right" cracked me good

**Important Note!** If you made it to the end, it's important to understand that the ~68% (or ~72%) discharge rate is absolute not a rule of thumb, just a fun guestimation. Every battery is unique, and will have its own unique characteristics. Also, looking at Rimac's latest high speed run, they achieved 412 km/h with *much* higher power after prolonged acceleration (the car was delivering 1225 kW at 412 km/h, or 87% of the peak 1408 kW). Porsche's T-Hybrid battery is also rated for "continuous" power at 41 kW, versus a peak of 48 kW - that's roughly 85%. So perhaps 70% is a low estimate, though it is accurate for the context of the original Rimac top speed run, and we don't have many of these data points (because top speed runs are a challenging thing to put together). Just some added context! Will be interesting to see some real world tests with the Tourbillon. Thanks for watching everyone!!

props to Mate Rimac, so grateful to see what happens when enthusiastics take control

I never even thought of this. The car is RWD in the ICE only mode. So we could potentially see some people do donuts and slides in the Bugatti Tourbillion. And with a high revving V16, it's definitely going to be banging off the redline like crazy.

People: Hey nice watch is it mechanical or quartz?,
Me: Its V16 watch

Couldn’t resist getting one more pun in, could you?

[rafiazmi]

Thats a nice drawing of the car you got on the board

[ashutoshtewari]

Btw Andy Wallace (Bugatti test driver) said that during the Top speed run for Chiron 300+ when they reached 490kmph, the car was still pulling, they simply ran out of space to push the car to its limit. So the power required as mentioned here can essentially be lower i.e. 1800 HP can do the job.

I'm sorry.... I still can't get over the fact that this man sold the best car in the world, the legendary crosstreck. What have we become

[Doctorbasss]

Mate said that the Tourbillon battery has Imersion cooling. Which mean it has the best cooling method technology at the moment. These new dielectric liquid are ultra performant. So holding 25C discharge rate is not a problem and sustained power is also improved even at the end of discharge SOC curve. The new cells they are using are ultra performant ultra low Internal resistance. Also One of the reason you see the power is decreasing on the Nevera is because the BEMF of the motor is getting close to the battery voltage so it become more and more difficult to continu pushing phase current to the motor( which is related to torque) as the difference of both( or the potential difference) is narrowing. The use of Field weakining generation to conteract that is not efficient so more and more heat is generated.

Mate confirmed on the stage at launch, redline is 9, 500 rpm.

You can also see it shift at 9, 500

0:47 Here I am, appreciating both watches and cars while having a bank balance to buy a new bicycle.

[grantlawler]

Been waiting on this. You can keep coming out with all of the Tourbillon videos you'd like! I'm here for it!

[michaelsteinbach]

Having that cool clockwork cluster in the middle of the steering wheel is pretty sick.

[julesbilodeau]

For an engineering guy, I think you went over what a tourbillon is kinda quickly (aka not at all).

In a mechanical watch, the accuracy of the watch will be affected by a wheel going back and forth to tick the movement, powered by a spring (this is called the balance wheel). The thing is, the rhythm of that wheel will be affected by its orientation (depending on the position of your arm wearing the watch).

A tourbillon is a very complex mechanism found on very high end watches that will constantly spin the balance wheel, therefore equalizing the variances created by the position of your arm.

Bugatti see themselves as the very best of car engineering and a tourbillon is pretty much the very best of mechanical watch engineering. The pinnacle measure of a car performance is speed and Bugatti has loads of that. The pinnacle measure of a watch performance is accuracy a tourbillon gives you that.

❤the data, presentation and explanation details; awesome as always!

[davidwilliams]

Ah, but Jason. You forgot Bugatti's secret weapon: special editions. And after that, a more special, special edition. And then the final production special, special, special edition. And then the very limited, "had to do this for a VIP special, special, special, special.... Special edition

[FXDE]

The tiny engine inside the watch it pretty cool. I'd like to see someone assembling that.
