Found a pic of the MC12 with front cover removed: pic URL .

What are those fans used for?

They give extra cooling to the radiators. They use the same setup as most Porsches. Radiators in the front (corners of the front bumper) and engine in the back

They are generating downforce and lots of aero mess.

On serious note - most of the cars has fans on radiators.

That was really worth a new topic.

Arrrr... sorry...

Didn't realize that you can put the radiator at the front while the engine is at the back.

Just the same as what you see in some racecars. Engine in front, radiator in the back.

Radiator isn't physically (spl?) attached to the engine so all you'd need are longer coolant hoses

I don't think it's such a bad question.

F1 and other formula don't always have fans on their radiators, and rely solely on forward motion to remove the heat.

The fans help keep the engine cool during pit stops, but may also help during the race by not needing such large downforce disturbing ducts to force the air through.

Quote from TypeRacing :

That's from the display car that's used at various PR events to provide additional cooling due to the slower speeds. The 'proper' race cars don't have those fans fitted at race weekends.

Fixed
