Nerd’s Eye View: LA Auto Show 2015 – Porsche


The side scoop on the GT4 has an internal divider. Some of the air is being fed to the engine, the rest is for cooling.
These are the optional Porsche Ceramic Composite Brakes (PCCB). Of course, super sticky Michelin Pilot Sport Cup 2 tires are used on the car.
Interesting thing here…. No brake cooling air guide. I guess the PCCBs do not need the cooling; cooling may actually take them out of their operating temperature range. Just a guess.
Here is a more close-up look at the front suspension. So you can see the bottom of the strut, the steering tie-rod, and the lower suspension arms. And no brake cooling air guide.
There is the vent for the hot air coming off the heat exchanger in the bumper to dump into the wheel well. You can also see the diffuser in the under tray sucking up air towards the brakes. The backside for the front wheel spat/air deflector feature is mostly closed off on the back side.
Ah, those seats! Fixed buckets with carbon fiber shells are used in the GT4. Padding is strategically placed in the middle section of the side of the seat, between the lower bolster of the seat bottom and the upper bolster of the back of the seat. That padding is perfectly placed as you have to put the thigh of your leg there to get in and out of the seat. So it will be a high wear area.
