this only applied to the 8v version, the rest of the range were a much-of-a muchness in drag terms.
Surely it doesn't matter what engine is under the bonnet, the body is still the same shape so should be as aerodynamic???????this only applied to the 8v version, the rest of the range were a much-of-a muchness in drag terms.
Aerodynamic drag coefficients
2.0i 8v : CD 0.26
2.0i 16v/2.0i 16v 4x4/V6/Turbo 4x4 : CD 0.29
I bet you'de be shocked at "today's" cars, there is onyl so far they can go and keep withint their design limitations. For example according to: http://en.wikipedia.org/wiki/Automobile_drag_coeff...
a modern F1 car goes from 0.7 to 1.1 dependant on settings

And F1 car is an open wheel design though, about the worst possible starting point for aerodynamics, and certainly not any kind of benchmark for a production road car.a modern F1 car goes from 0.7 to 1.1 dependant on settings

Every Veyron cost VW well over £1million to develop, all sold at a massive loss to the company.

You've been listening to Clarkson too much. The Veyron project is in profit according to Bugatti's boss http://2010bugatti.blogspot.com/2009/07/veyron-pro...

Pub ammo bit" A McLaren F1 gets from 100-200 quicker than an F1 car (albeit a contemporary one, not sure how that stands up today) and is far quicker once above 150. But less stable.
Interesting link BTW, just found out the current Seven is no more slippery than a 20 year old one, which surprises me a lot. And the 8v Calibra is the same as a E90 Three Series (presumably the 320ED as others are up to 0.30)

But it aids braking hugely doesn't it? That and if all the air is passing smoothly by, there's no way to produce downforce? I'd have assumed high aerodynamic drag was in some way a price to pay for the downforce effect.
It probably helps with brake cooling I suppose. Some drag will be from the wings producing downforce, that is an inevitable trade off and why the Wiki article shows a range of drag figures. However, you could significantly reduce overall drag by enclosing the wheels like LMP cars do.Zwoelf said:

The other thing is that F1 cars have very very very small frontal area, so despite having very high Cd, they have much less than expected drag at a given speed.
Remember that Cd only tells part of the story; a greyhound bus has a Cd of arond 0.3, but huge frontal area.
As for the Veyron thing, yes, each one was sold at huge loss, but VW have always been adament that the project was an engineering exercise and not one to make money.

Shows what a difference to aerodynamics just a set of wheels can make.

at 8 feet long the cambelt on the Porsche 928 S4/GTS is the longest of any production car. (this is an old fact, though I can't think of anything to over take it)
Probably as most bigger V engines run chains do they not? Only other belted V8s I can immediately think of are Lexus and Ferrari/Maseratis. jesta1865 said:
as for aerodynamics on cars i would have thought the next big breakthrough will come in paint design, a paint that lowers the friction or creates a void round itself similar to the 'shark skin' swimming costumes ?
