OMG!!! What did it sound like? This makes my spotting of a white LP570-4 SL and a black G-Spyder in Marina del Rey this morning inconsequential.
I haven't seen it, but I'm guessing it sounds like a Prius most of the time. When the gas micro turbines actually kick in, it might have some cool noise?
It sounds just like a Tesla. Oh wait, Teslas don't make any sound . The car was completely silent, but I'm guessing it was running only on electricity since it only drove a few feet to get on the truck. Still, it was amazing getting to see this car moving, even if it's going slower than I walk. Here's a video, enjoy! http://www.youtube.com/watch?v=cgmXGk6R3gI
