Mate, i don't know what part you're having problems with here. The Veyron is faster in a line at all speeds than any F1 car. Understand? The Veyron is limited to 250mph. LIMITED. It will go well over it.zewulf wrote:Perhaps Mr. Mansell forgot about this car, or he wouldn't be so scared of the Veyron in a straight line
A little background on this for those who don't follow F1:
The BAR Honda F1 team wanted to set a land speed record for F1 cars by topping at least 400 kph (about 248.5 mph), the same top speed of the Veyron. They originally intended to do the run on the Bonneville Salt Flats in Utah, but because it's been raining there the past few months, the place has been flooded. So instead they decided to do some test runs at an airport in the Mojave desert in California (they still want to do the official run on the Salt Flats sometime next year). For the test runs, they went over 400 kph at least 3 times, with the highest recorded top speed of 415 kph (about 258 mph).
As you can see from the pics, it was a modified BAR Honda F1 car. I suspect the engine probably developed at least 1000 bhp, and they replaced the typical rear wing with a rudder-like tail wing. They claimed the car was still race legal, but as you know, their definition of "race legal" is very much different from everyone else's...
I'd be fucking scared of driving the Veyron in a straight line. At least the F1 cars have plenty of downforce going on....Doombrain wrote:Mate, i don't know what part you're having problems with here. The Veyron is faster in a line at all speeds than any F1 car.

According to that article by JC, the top speed of the Veyron is aerodynamically limited and not electronically limited. They had to make aerodynamic compromises to enable the Veyron to hit 400 kph. To hit the top speed, you have to lower the rear wing, or you wouldn't hit it. I really don't believe the Veyron is faster in a straight line at all speeds, for reasons I've already mentioned in a previous post.Doombrain wrote:Mate, i don't know what part you're having problems with here.

With this done, the Veyron was shipped to Sauber’s F1 wind tunnel where it quickly became apparent that while the magic 1000bhp figure had been achieved, they were miles off the target top speed of 400kph (248mph). The body of the car just wasn’t aerodynamic enough, and Volkswagen wouldn’t let them change the basic shape to get round the problem.
...
Somehow they had to find an extra 30kph, and there was no point in looking to the engine for answers because each extra 1kph increase in speed requires an extra 8bhp from the power plant. An extra 30kph then would need an extra 240bhp. That was not possible.
...
However, with the spoiler in place the drag is so great you’re limited to just 231mph. To go faster than that you have to stop and insert your ignition key in a slot on the floor. This lowers the whole car still further and locks the big back wing down. Now you have reduced downforce, which means you won’t be going round any corners, but you have a clean shape. And that means you can top 400kph.

Geez DB, can't you read? It wasn't like they were already going way over 250 mph that they had to hold the car back. The problem they found was that the car could NOT reach 250 mph. So they had to make all these aero changes (not just with the addition of the adjustable rear wing) so that it could. And no one's saying it's exact. What they can do is to approximate it with CFD in the wind tunnel to know that the car will be aero limited at about 250 mph after taking into account engine power, mechanical losses, etc.Doombrain wrote:You can’t aerodynamically limit something to an exact 250mph. It’s electronically limited to 250 because the tyres are not safe to drive over 250mph.
Jesus.
