Think you know your 911s? Really know them? By ear? Well, hit up the Porsche Evolution 911 Competition to test your mettle. If you win, you'll get an Evolution 911 driving experience at the legendary Silverstone circuit.

It's simple enough: you listen to an audio clip and choose which of three historic models the sound belongs to, ranging from the 930 911 Turbo to the racing 936 to the 997 Carrera and many in between.

To win, you must first get the answers to the quiz right. If you do, your entry is then among those eligible to be drawn for the grand prize, an Evolution 911 driving experience at Silverstone. As the location implies, the contest is being run by Porsche UK. From the looks of it, however, residents of other countries are also eligible to win.

Whether you are interested in the prize or not, it's worth listening to the clips just to hear the sounds of so many Porsche flat sixes. Hit the link below to have a listen--and a go--for yourself. Porsche also offers a download of the wallpaper pictured here for those that complete the form and submit their entry.
