It was bad enough when Porsche and Nissan were duking it out over the actual speed of the GT-R around the Nurburgring, but things almost stepped up to the next level--law suits--over the silliest little ad: a 370Z with BMW, Audi, and Porsche badges with hash marks beside them, indicating superior performance around the Green Hell. The ads were shown at the Goodwood Festival of Speed earlier this month.

So why was Porsche so (reportedly) hot under the collar over the ad? Turns out they're not threatened by the Nissan's performance. Rather, they object to the use of their logo in the ad, which was done without permission.

In the end, it didn't come to a legal wrangle because Porsche approached Nissan and demanded it stop use of the logo, which Nissan did, changing it simply to the Porsche name. Legal action was threatened, at one point, however, according to the Guardian, so it wasn't a completely amicable transaction.

Where will the next round of the Porsche-Nissan battle royale be held? And who would you choose to win in a brand-versus-brand throwdown? Let us know in the comments below.
