Hard to say because there's still so much camo, but I think we'll see those vents. Not only because the 1M had it, but because it'll take a lot of cues from the Vision Gran Turismo concept. We've already seen that the front bumper will have the same style. Check out the rear:
On another note, I'm getting antsy about this car. I spent all weekends reading the same threads over and over again. Would love to see more pics or videos of the test cars!
