Nerd’s Eye View: LA Auto Show Part 2 – Cars & Stuff

,

A pair of fans regulates the temperature around the rear mounted engine while the car is stationary.  When the car is moving, the scoops on top of the rear engine cover grab the air and force it down. It still amazes me a bit the scoops are able to effectively grab the air coming off the rear window.
Porsche recommends Mobil 1 too. Interesting about the little sticker there mentioning the octane knock control. Apparently, our Cali 91 octane fuel is so poor, even stock 911s knock on it.
Due to the rear mounted engine and exhaust; the rear diffuser can’t extend too far forward.  The mini-keg looking thing should be a close coupled catalytic converter right at the collector for the tubular headers. To the left, you can see the vacuum actuator used to uncork the exhaust at WOT; it’s docile when stuck in traffic in Beverly Hills and rips a magical exhaust note on the track.
Check out this lower suspension arm. It appears the length may be adjusted by placing shims in it. So you would undo the nut on the threaded stud, pull the arm apart a bit and place a shim in there and tighten it back up. Or… I could be completely wrong. Looking up a bit, you can see the coilover shock.  Looking forward a bit, you can see the rear sway bar. As for the tire, it’s the new Michelin Pilot Sport Cup 2. The inner shoulder block length looks pretty long before getting to a central groove which should put a good contact patch down.
Something new on the GT3 this year is the active rear steering. At the top of the picture is the electric actuator used to steer the rear hub. The long black plastic piece right under the steering actuator appears to be a rear brake cooling duct. This is a Porsche GT3 after all and these things are designed to live on the race track.
Of course, there’s the front control arm mounted brake duct. Check out the outside shoulder of the new Pilot Sport Cup 2; that’s a lot of meat for grip.
As the GT3 is designed to go as quickly as possible around a road course, it comes with two pedals only as the transmission is the ultrafast shifting PDK. Gotta love the bottom hinged accelerator pedal.
As the car is designed to go as quickly as possible around a road course, it expects the driver to be in similar fit condition. I’m 5’10” and 145lbs, and the driver’s seat was a snug fit in the upper torso.  If you need to trim up, a bicycle is a great way to do it.
9000rpm redline? Yes please. Being an instrument for going quickly, the tach is properly located front and center.
