I encountered my first new Civic Type R in a mall today. I took this picture of the rear side aerodynamics the spoiler and the vortex generators and other features. Reminds me a little bit of the design of the Subaru WRX with its vortex generators and high spoiler.
Here is a flashy and somewhat useful commercial technical description. Aerodynamics 0:37 - 1:07, with the VGs description at 1:01-1:07.
What amazes me a little is that they go to such lenghts and cost to develop fancy aero tricks in the tail end when a cleaner "template" shape would be better to start with. Doesn't the heavy modification of the notch/hatch body type here just induce more drag than they might otherwise create using the template and maybe a modest spoiler for lift reduction? Marketing, I guess.
Also... Though the design cues are too busy and noisy for me (it's a steel anxiety attack), I do understand the excitement about this car. It was cool looking in the lot.
