For the better part of a decade, Mazda Motorsports has hosted a media day highlighting their racing activities.  They also bring out some pretty cool hardware from their racing history.  This year, the headliner of the show was the new SKYACTIV-D ('D' stands for diesel if you hadn't figured that out already) racing in Grand-Am.  Mazda Motorsports not only showcased the car, but also had Sylvain Tremblay of SpeedSource along with one of his engineers to do a tech deep dive.  Follow along to find out a few of the details on the new SKYACTIV-D power plant along with some gratuitous pictures of their other racing hardware.
Front and center was the SKYACTIV-D Mazda6 Grand-Am car.  Look beyond it though, and there's some really cool hardware back there.

How can you not love the Mazda 787 with the 4-rotor?  Check out the NACA ducts and air openings feeding heat exchangers down the driver's side of the car. 
A view of the driver's side from the rear shows the exit path of the air going through a heat exchanger.

A heat exchanger is mounted in the nose of the car with the air going through it being dumped over the top of the car.  Dumping the air on the top-side of the car should help reduce front-end lift.
The right side of the car has some other shenanigans going on with the exhaust exiting the side of the car before the rear wheel.
