Do F1 teams sand the surface off their carbon fibre? If not, why not?

Presumably because there is no point in saving weight when you are not allowed to drop below regulation weight which was so easy to do that some cars had to add weight to their cars.

It's not that easy to do ! But when your under weight you can ballast your car with the bias to suit your needs
Normal f1 bodywork is a VERY light layup
Quick 240 grit Abrade an a very light colour coat

Since epoxy resin in pre preg isn't UV stable I would like to see what this looks like in 20 years
Got some old f1 stuff from 20/25 years ago an that's degraded just being in a shed not out I'd direct sunlight

Got to assume/hope they will have thought of that and used a UV stable resin. They're either hand weaving this stuff in house or getting it made specially for them, either way not off the shelf pre-preg so they'll have had the chance. With the advancements in carbon materials over the last 20years I'm not sure that old F1 stuff can make a decent comparison.

It must have been nerve wrecking and time consuming for the guy doing the sanding, you get too far through the top layer of resin and surely you're at risk of damaging and exposing the fibres! I would not want to be the guy who damaged one of the single piece front/rear clamshells!

Love what Koenigsegg do. I suppose its easier to make innovative decisions when the boss is a brilliant engineer sat across the room from you!

That is something else.

I'd sell my grandma if it meant I could buy one.

Thought I'd read somewhere that the Regera's top speed is around 250mph? Although I'm not sure why it would be slower than the Agera RS.

This is a very misleading article. Of course it still has resin, that's what's bonding the bloody carbon fibres together.

There's something about Koenigsegg. They seem to carve their own path. Like a modern day Lamborghini of old.. (If that makes sense)
I can really warm to their cars where as the likes of McLaren etc seem to leave me cold.

Somehow they seem to have successfully combined 'efficient' with 'utterly bonkers' and ironically when you compare it with the Mclaren Senna, it looks far less 'try hard' and even has a degree of elegance. Don't ask me how they do it.

Well done lads and lasses at Koenigsegg.

Ezceptional car,exceptioanl company. For me it does fall into auto porn, something of fantasy as I will never own one, drive one, or even see one reality. Just glad it exists - not a corporate halo car or the Nth variant of a performance line with 25 different models.
The whole company is strangely old fashioned in concept - sort of a modern Delahaye

completely agree. Glad that these guys exist. a superb-looking car. If it's at the cutting edge of tech too, that's a bonus.

Trust me,there might be a few different resin systems from 20yrs ago but it's all pretty much the same
Mostly all the cloths are woven in japan/China the difficult part is getting a resin system to use if you want to make your own cloth.
Don't know of any UV stable systems
There isn't a top layer of resin with pre preg,resin is all the way through

Are we sure? What could be cooler than a car you have to ravel every time you drive it?

I feel sad because inevitably one of these things is going to be purchased by one of those big headed YouYube tts who will promptly take it to a mechanical car wash...

Firstly, who do you think should be driving this car then? I don't understand - are you saying only a certain type of person should be allow to buy this? That opens up a whole set of questions, none of which are very pleasant...

Secondly, what makes you think that someone with the required money to purchase a car like this would take it to a mechanical carwash?

Finally, if you were in your early twenties with a load of cash and able to purchase pretty much anything you wanted, whilst also being an internet celebrity, YOU'D be a big-headed tt too.

You seem utterly determined to start an argument no matter what. Calm down and watch this...

To get this degree of perfection over big curvy shapes I suspect this carbon is neither pre-preg nor laminated dry cloth with resin added but rather wound filament. The process drags individual filaments through the resin and winds around a buck, which gives a lot of control over weave hence you can engineer in strength where you need it and lightness where you don't. Expensive and time-consuming, plus a complete ball-ache. But the end result is properly conformal shapes and consistent weave pattern.
If they haven't done it that way then they should have done
