252mph, New Production car speed record

PSZeTa · Post by **PSZeTa** » 27 Sep 2005, 14:26

The F1 is a road car. It's not that the speedo suddenly gets accurate when you get on a track..

The speedometer was acurate all the time. Just in case they probably did test it to make sure it was right on.

Don't be so sure that the speedo is dead accurate.

Here in Aus, road cars' speedos only need to be accurate within 10% (which is stupid because you can get busted for going 5% over the speed limit). So that means just about all cars are not perfectly accurate. Top end sports cars are no exception.

I'm giving the driver and crew the benefit of the doubt, the 391kph is the speed, 391 translates to 242.9 which in turn is rounded out to 243 mph.

I know speedos are usually a bit off, most cars I've driven are 10% off (when the speedo say 80 kph, I'm really going 70 kph). So I SHOULD be safe until the speedo reaches 95. But that's for normal driving.

I belive that the video shows the correct speed, because it seems to be a proper test. I believe he is using some sort of equipment to show it (notice how he says 386, 388, 389, 390, 391 at the end). There's no way you can get it that accurate on a normal speedo, unless it's digital... But I'm also sure they would know about speedos being wrong on cars, and therefore use their own - reliable - equipment.

There is one error in the video tho. He says he thinks that record will never be beaten. The Veyron beat it...

I'd love to see Bugatti do a video like this.

I don't know what the exact power to weight ratio is but it isn't as high as with some other cars.
I did some calculation for you Stiggy.

Bugatti Veyron 16.4:
1900 kg & 990 hp = 1.919 kg/hp.

Mclaren F1:
1140kg & 627hp = 18181 kg/hp

Exige:
870kg & 190hp = 4,58kg/hp

So the McLaren is better

World Class Motorsports Ultralite:
524 kg & 240 hp = 2.18 kg/hp
Now, you can also get a WCM Ultralite with a Factory installed turbo or supercharger (meaning you can still count a turbo'd WCM Ultralite as a production car) in which case you're looking at
524 kg & 360 hp = 1.46 kg/hp

Now keep in mind it's not very aerodynamic, so it cant hit anywhere near 252mph
BUT! then again, the Veyron is going to cost 1.2 Million (if you can find anyone to sell one for that price. keep in mind the Ford GT stickers at 140,000... try finding one for under 200k) and the WCMUltralite with a factory turbo will run you about 37,000

No comment.

It's been known that over the years french technology is inferior to everyone else's. That is what I heard.

Well they invented air-suspension.

But besides that they do indeed suck.

Post by **Pabl0z** » 01 Oct 2005, 13:06

And the air-suspension sucks

.Our family once had a Citroen and was only about 5 years old at the time and what do you know... The suspension broke one sunny afternoon. And repairing it costs a fortune.

Post by **TheStig** » 01 Oct 2005, 14:36

To bring a end to the speed faults

the test with the McLaren was done with all kinds of equipment in the car.
including speedmeasurement equipment. and I doubt that they use equipment that as a flaw build in.

but who cares.... the bugatti beat it. even if it was 243 mhp.

I'm a big fan of the McLaren and I think it is a overall better car then the Bugatti.
Even if it only was because it simply looks ALOT better.

someone said 1000 BHP can cure alot... true but don't forget that the McLaren did 10 MPH less with also 400 BHP less!

btw about the Hydropneumatic suspension made by CitroÃ«n it's not without flaws

since the C5 came the suspension didn't give any real problem anymore.
But before that it broke down alot.The Xantia had problems with it also....

Then why is Renault winning so many races in F1 (and maybe win the constructors championship)
And CitroÃ«n can win the WRC again.

Because Nissan's parts are in the car.

Renault and Nissan are in a partnership, Renault owns some of Nissan and vice versa.

Bugatti is a French luxury car maker. Search bugatti. Molsheim France.

Malaegryn · Post by **Malaegryn** » 03 Oct 2005, 07:15

search the terms bugatti volkswagen. volkswagen bought them out before the veyron went into production, and the engine/transmission and most of the rest of the chassis is straight VW and Audi design. i cant speak for where the body design or final assembly took place, as that most likely was in france, but being put together in france doesn't really make it french. most BMWs sold in america have final assembly in the states, doesn't make them american.

James31278 · Post by **James31278** » 03 Oct 2005, 17:22

It's french everyone and his dog knows it. It's makes BMW still better than Mercedes.

It's German, thank you.

James31278 · Post by **James31278** » 03 Oct 2005, 21:55

French, Volkswagen owns it as a French company producing french vehicles in france. So their site says.

I've seen that Tomahawk on tv before. Man did it hurt my ears.

So because Volkswagen Bougth it it is instantly a German car company.

then I think you got some explaining to do to the people that work for Seat and Skoda and tell them they work for a german car brand...

If I get it right, Volvo is a American Car company cause it is owned by Ford and Aston Martin is American also cause it is also a part of Ford.

NO Volvo is still Swedish and Aston Martin is still Brittish

SEAT is still a SPANISH company.
Skoda isn't german eighter.

in other words YOU ARE WRONG.

Bugatti is still a FRENCH company!
yes they do use alot of parts from volkswagen or audi but that is a classic trademark of the VAG.

Thank you Stig.

What he said!

Mazda is partly owned by Ford too. Renault and Nissan have a partnership, Renault owns 40% Nissan owns 15% of Renault. I should be the other way around, Renault the one on bottom.
