They keep spelling carbon fibre, carbon fiber! Grrrr!

Other than that, that is very very interesting! 999Kg kerb weight for such a big car, wow!

Serious bit of kit, awesome bit of technology.

And shouldn't "curb weight" be kerb weight too ...

And shouldn't "mold" be mould?

Well if we are going to be like that it states a curb mass then gives figures in Kg and lb.
Mass is totally distinct from weight and neither of those units is used to quantify it.

I've stated it elsewhere, half of everyone you meet is of below average intelligence.

Very nice. I've seen the CF trims and engine covers on my mates RS4 and they are nice pieces.
They use resin infusion to make similar parts like injection moulding so the finish is top quality. Downside is there is a lot more resin needed to produce the parts so can ultimately make the parts heavier than they really need to be. Its done by lining a mould with dry carbon sheets and then sucking resin into the mould via a vacuum so no air is present in the whole process eliminating any weak spots in the mould.

F1 teams have experimented with the process but still isn't as good as prepreg layup and autoclaving so they gave up trying.

You need to be more specific.

Mean, Median, or Mode.

I have a feeling you meant mean, in which case your statement is wrong

CG - Thanks for your statement. I was going to ask why F1 Teams weren't using this material, but you beat me to it

Still, from what i've read, this CFRP is a lot cheaper to make than the pre-preg autoclave.

It would be nice to see a move away from metals where possible.

Ah! somebody who knows statistics:

I once used to think that correlation and causation were the same thing.
Then I went on a stats course and don't any more.

<voice of third party>
So the course helped?
</voice of third party>

There's no way of knowing that...

The whole "measurement of intelligence" thing is a mine field so I don't want to get into it too much but the gist is there...

I can see the NSX's wishbones being a LOT easier to cast in ally.

But like most things, success is 99% failure and one day they might find a way to do the short-strand stuff reliably & cheaply.

Still, unlike most modern rubbish, a V10 4WD for the same mass as a TVR is quite an achievement.

Having said that, Lambos built out of traditional aluminium are usually the right side of 1,500Kgs. Which is very good, and shows how hard this must've been.
