Nerd’s Eye View: 2012 LA Auto Show

,

The rear diffuser is quite substantial and also has a heat exchanger mounted to it.

 

This is the new Porsche Cayman.  I need to drive one someday.  Sitting in the Subaru BRZ feels very similar to sitting in the Cayman.  I think it’s a good bet Subaru benchmarked the Cayman. 

 

The bottom-side of the car was sporting some new features I haven’t seen before.  The flat air diverter in front of the tires is nothing new as plenty of cars have them.  What are new are the rounded things in front of the flat diverter.  I’m guessing they help direct the air to the sides reducing the drag.  Just inboard of the rounded diverter thingys is a diffuser which channels air upwards.

 

The diffuser channels the air towards these air guides that direct air towards the brakes.  Looking towards the rear tires, you can again see the flat air diverters. 

 

The air is directed towards the rotor.  Notice the dust shield has a cutout to allow the air to directly get to the rotor.
