Yes (or probably fans - plural).

During aerodynamically relevant high-speed driving, the demand for cooling is considerably lower. The different cooling-capacity and cooling-air demands under those operating
conditions had to be taken into due account. And in order to realize a most efficient and demand-adapted cooling-air concept it was important not to overdimension the
cooling-air requirements either.


So all this bumf from Aerohead is just because on the track (not at high speed on the road) the radiator fan comes on?

Really? That's some great conspiracy that only Aerohead can reveal?

The rest of us can admire a car whose design gives extremely low aerodynamic cooling drag.

Talk about losing the wood for the trees.
Admiration for a low aerodynamic drag cooling system is overshadowed by the un-mentioned so-so overall cooling drag. An externality. The major portion of cooling drag has been exported to the fuel tank, which will bear the ultimate cost of limiting 'cooling' drag to only what can be ascertained in a wind tunnel. Legerdemain. Intellectual dishonesty? Do pedants even know?
Congratulations, you've extended Porsche's piston sales another day.

I get the part about right-sizing the ducts.
Yes, two, high-speed, electric 'puller' fans, one on each side.

Apparently so.

Really? That's some great conspiracy that only Aerohead can reveal?

Apparently so.

A perfect example of the sort of thread that Aerohead creates. A weird theory built on sand with the primary purpose of riding some strange Aerohead hobbyhorse.

I find it surprising that people continue to take Aerohead's posts seriously.
