This video, from YouTube user DrGumoLunatic, shows what looks to be a 2013 Porsche Cayman in heavy camouflage. But it's not the rather dark video that's the most interesting part--it's the sound the Cayman emits.

The throaty exhaust note at startup turns into a healthy rumble on acceleration, hinting at sounds the new 2013 Boxster may make as well, if we could get the annoying soundtrack off of the official video.

We'll keep you posted on more developments on the 2013 Cayman that will share in the new Boxster's updates, both visually and mechanically, but in the mean time, you can check out our own spy video of the 2013 Cayman, as well as our detailed spy shots.

Thanks for the tip, Toldi!
