Recently, I learned of a way to make a Bugatti Veyron go 300mph in Gran Turismo 5. For an idea of just how fast that is, the yellow distance markers flashing under the car are at 100m intervals. Of course, you can go 311mph - and much more easily too - if you use the Red Bull X2010/11 prototypes, but this is a road car going 300mph, and that's much more challenging to do than when you have 1600 horsepower, 545kg and a fan sucking you down to the road like the X1s. But it's got me thinking: how long will it take for a real life production car to break the 300mph barrier? !!!error: Indecipherable SUB-paragraph formatting!!!

300 MPH isn't crazy, considering that FC and TF dragsters have been doing it for years in just a quarter mile of track. 300 MPH in a car designed to go more than straight? That's a few years out. I bet we see it by the end of the decade, though.

Of course, it won't involve fans and a horsepower number as low as 1600, because the X1 is horribly unrealistic and not really related to real physics in any way.

Ultimate speed has little to do with weight. In many applications you want more weight, which should explain the Veyron's ~2 tons.

Power required to overcome drag increases as the cube of speed.

Dependent upon air temperature, my chassis only requires ~530whp to do 200mph. To do 225mph takes ~775whp, or ~46% more. To do 300mph would require about 1900whp. This is with a small frontal area and a slippery .29Cd, the Veyron is listed as .36 in Top Speed mode. And even with that much power, it would still take 5-7 miles depending on conditions.

Just food for thought.

I miss my PS3..

*She got ill after my girl spill an earl grey tea on it..

So I have to boot back old GT2 on my phone. And drive this Nissan!

19000hp FTW!

Pretty sure they ran it through the same simulations as their F1 cars. Obviously it stayed virtual, but I still think we can at least get very close to the X1 in real life, given the chance. They made sure it was technically possible... just.

At any rate, I agree that we can hope for a 300mph road car by 2020.

Not at all. Actually developing that car at RBR would have cost millions of dollars. They gave Newey a goal and he came up with a drawing and then PD developed it from there.

There's no way you could get anywhere near the X1 in the real world. Given an unlimited budget and no regulations, you could definitely make a road course racer that fast in a straight line (and you could probably break 300 MPH at Indianapolis), but you sure as hell couldn't do it with just 1600 horsepower, teardrop fenders and a fan on the back.

It's an improvement on the Nike car from GT4 but it is in no way anything resembling realistic. It's just some ideas Newey thought were neat that are nowhere near any real practical application put together.
