I suspected that it was the VDE (equivalent to the US FCC) requirements, and I expect most countries now have similar regs! On GM cars with metal bodies and plastic hoods (Camaro, for example, aluminum foil is applied to the underside of the hood, and that foil is grounded by a couple of braided copper straps! The RS 2.7 could have used such a fix, too!
No, the grill is not a problem on most models of 911, because underneath the bars of the grille lies a nice mesh of expanded aluminum, quite effective at frequencies under 10 GHz or so!
And, Robert, if you doubt that there is lightning under the hood of a 911, just look at the warning sticker on the coil. And, talk to anyone who has grabbed a Beru connector and wiggled it to find out where a mysterious miss was coming from, only to find out what 50KV feels like traveling through the body from hand down to kneecap or so while becoming the return path for said ignition impulses!
