Rennsport Reunion V is right around the corner (September 25-27th, 2015). Chances are, while you still might be able to get tickets, you'll be hard pressed to find a hotel or flights. Even if you do, wouldn't it be so much better if you were a guest of Porsche? Here's your chance.

Are You A Porsche Motorsport Expert?

Porsche has created a simple, interactive site that plays the sounds of four (4) iconic Porsche race cars. All you have to do is match the exhaust sound of each engine to the appropriate car. You can try as many times as you like (admittedly, it took us two times) and once you've made the matches you'll be offered the opportunity to enter by providing some basic contact details and agreeing to fairly common terms and conditions.

Whatever you do, don't wait. The contest ends on the 14th of September. If you're chosen as a winner, you'll get tickets and parking to the event for you and a friend. Along with those tickets comes business class airfare and hotel accommodations. Enter here.
