Why do some tuned cars have a black bonnet?

Question

I noticed that there are a lot of sporty 'tuned' cars with a black painted bonnet even if the car has a totally different color.

Why is this? Does it have a function or is it just with no particular reason at all?

I do know that fighter planes used to have the nose painted black to prevent reflection of the sun on the metal surface but that doesn't have anything to do with these black bonnet cars right?

Answer 1

Black bonnets on tuned cars are usually because it has been fitted with a carbon fibre bonnet which is extremely light and strong, or it's been painted black to look like that, or even it's a new bonnet and it's still in it's protective black primer! The racing world do bonnets matt black so that they don't reflect light thereby keeping glare down.  

Answer 2

Because they're loosers

Answer 3

You had it right, to prevent glare when racing!! This is before carbon fiber was even invented. So, I suppose this is the original reason. The new reason could be to emulate carbon fiber. But carbon fiber can be painted, so, I stick to the original reason. Prevent glare.

Answer 4

Its either carbon fiber or painted to simulate carbon fiber which is lightweight. Its styled after 90s race cars back before they painted carbon fiber-
