Len,
Not just the +8, but also the 4/4 and the +4 (but, apparently not the new
Aero 8) have louvres. I'm not an engineer (aerospace or otherwise) but I
suspect that, when the car is in forward motion, the louvres force the air
rushing over the bonnet away from the bonnet and create a partial vacuum to
help suck the air out. The only other way for air to escape is through the
bottom of the engine compartment. I agree, the louvres look cool but are
hard on the finger tips when polishing the car. But, "no pain, no gain."

Subject: Louvers in the Bonnet
The Plus 8 has louvres in the bonnet.
They look cool; but I don't know how
much they keep the engine cool.
I don't know how they work going down
highway (haven't climbed out on the
bonnet, yet). I have put my hand over
them after I've shut down the engine
and the electric fan is still running--I
get a lot of hot air coming out. One could
theorize that the fan is pushing air over
the engine and through the louvres
