Nerd’s Eye View: SEMA Edition 2012, Part II


This past year, regulations were introduced which led to these openings over the wheels on LMP cars.  The goal of the openings was to keep the cars from taking flight when the cars got sideways in a spin.  The exhaust dumps on the top of the bodywork and looks to aid in creating downforce based on the kick-up of the rear bodywork.  I’m curious as to what that silver tape is made of to protect the bodywork from the heat of the exhaust.  Of course, the rear wing uses the swan neck mounts that have now become commonplace in top level motorsports.


There’s some intricate air turning devices behind the rear tire.  Notice how far forward the rear diffuser goes.  Being longer typically improves diffuser performance.


Here is the Audi R8 LMS ultra that won the 24-Hours Nurburgring in 2012.  I love the bodywork on this thing; the front splitter, canards, fender louvers and that big hood vent.


Do you want to know the proper way to duct a heat exchanger?  This is it.  The opening is well sealed against the heat exchanger.  The leading edge of the opening has a deflector which should kick up the air hitting it from the front creating a low pressure area behind it.  That low pressure area will help suck air through the heat exchanger and out the hole in the hood improving cooling.


We saw this bodywork on the GMG R8, but I still can’t get enough of it.
