Why Has No Car Ever Hit 300 Mph From The Factory?

The most impressive thing about the Bugatti Veyron is not that it can do 267.8 mph flat out in Super Sport trim–it is that it can do it without overheating in spectacular fashion afterwards.

That’s what makes the Veyron the technical achievement unlike anything else in the world. In his latest video, Engineering Explained’s Jason xplores the tricky catch-22 of developing the car like the Veyron.

Essentially, if you want the high top speed, you need big power, but that requires the lot of cooling. The more air you send to the engine, though, the more you increase drag, which slows the car down.

A standard, non-Super Sport Veyron has the drag coefficient of .36 Cd, the same as the Cadillac Escalade. That’s why it needs 1000 hp to exceed 250 mph.

What would it take to push the Bug all the way to 300? According to Jason Fenske’s math, about 1800 hp would do the job.

Of course, you could theoretically get the road car to 300 mph with much less power if you had the more aerodynamic body, but you would almost assuredly blow the engine due to insufficient cooling air flow.

There are other factors beyond drag to consider, well, too–you have to account for the rolling resistance of the tires, the parasitic losses in the drivetrain, and more and more.
