It's a new '14 base Cayman PDK. Here's a video recording the noise:

It sounded like it was coming from the engine and not the road. The noise sped up as the car picked up speed and slowed down with the car too. It's only happened once so far. I already drove over the same road again and the noise didn't come back. I'll go check once more but I suspect it was from the car itself.

So what do you guys think, is this normal or trivial? It'd be nice if I'm just being clueless!

Thanks in advance!

 

The car is new, under warranty. There may be a new car problem, so best get it listened to by a tech.

 

Sounds like a sticky brake caliper in the rear?
