It helps isolate the heat of the engine bay from the battery and brake fluid. Not much, but it does. Many cars have this, including my Mercedes E320. The only difference is with the Mercedes it has seals and the hood acts as the cover, so it's not as obvious. But it still isolates the hot engine compartment from the brake systems/battery (or in the case of the Mercedes, the electronics - which are put where our batteries are in the Z). I'd bet it reduces temps in these areas at least 10-20*F. Cooking your brake fluid is not a good thing, trust me.. I know..
