You wanted me to stop reading right after this, didn't you? Well mission failed, although it is an extraordinarily stupid statement. You seem to have never driven a car at high speeds and on a track and do not know that being concentrated on one thing takes away from the other.
You tend to think that the 0.36 Cd (poor figure by the way) comes from the amount of wings and spoilers to provide downforce, not from vents to provide cooling. Also if you think a Cd of 0.36 is "aerodynamic perfection" then you're sadly mistaken. Cd has nothing to do with aerodynamic perfection, as with everything in a car's setup perfection is in ballance.
It's neither of the three things you listed. Also the SS laps Dunsfold faster than Ascari A10, Gumpert Apollo, Koenigsegg CCX and ... you can use google to find out what it's faster than if you're really interested. Ones mentioned are pretty much track cars, apart from Koenigsegg which is still undecided if it wants to be something in particular.
Sigh... and here I was, just a few posts ago, stating that somebody might actually think "I wonder what is he on about, I should GOOGLE", and here you are proving me completely wrong.
FINE, I shall explain to you how a Veyron was created. (I thought EVERYBODY in the car community was following the car ever since it was a concept, but it turns out everybody just thought "we should not pay attention". All this was in magazines, how the hell did you miss it).
In any case
In the year 1998 VAG bought rights to Bugatti, Bentley and a few others. To revive the interest to the brands they created a number of concepts. For Bentley and Bugatti they used a similar chassis and produced Chiron, Veyron and
Hunaudieres (That one is a Bentley). At the car show (I do not recall which exactly) as Veyron was demonstrated for the first time a lot of buzz surrounded the return of Bugatti, so naturally Mr. Piech in his usual fashion started making promises (Diesel Estoque is his promise aswell, thankfully that never happened). So when the press asked for details, he made the widest claims he could at that moment. 2.5 seconds 0-100 (Quickest car in the world), 400 kph (Fastest car in the world), 1000hp (Most powerful car in the world) and he pointed at the concept and said - THIS IS IT. Now note, the car was a rolling chassis with no engine in it, more so the engineering department had nothing to do with it, it was a designers' baby.
It was only AFTER that, that Ferdinand Piech told the engineering department what he had promised. So here you are, imagine if you will, an engineer who is given a shell of a car and the things it must do once you're done with it, most of them to be "first ever to do so", and what you have is a car shaped a tad better than a brick. More so, the car must not only be able to do it more than once, it must do it day in and day out, stay on warranty for FOUR YEARS. Go ahead, tell me that it's a "piece of cake". Then tell me that you'd slot in anothe engine into it, considering it barely has room for 4 cylinders in a row in the back of it, so you're stuck with an audi 4 liter v8 or a w12 which would not exist for 2 more years (In it's concept form) after you've started. And then figure out the fact that no matter how you look at it you need a LOT of displacement for the engine to be reliable at that power output for such a long time.
The only real reason for
Is because you have no idea what you are talking about.
