Test Driver Ratings & Comments
Acceleration commentsRetest after codes were reset by Porsche: With SC+TC off and throttle pinned to the floor, there's a built-in rev-limiter/launch mode at 4,200 rpm with boost hovering around 11.0 psi. Getting off the clutch pedal abruptly allows wheelspin, but it's relatively easy to modulate. A good sub 2.0-second (to 30 mph) launch is repeatable. First gear is over so quickly that it's critical to watch the shift light and not the slow tach needle. There's still some electronic reduction of power between each upshift (presumably to protect the driveline and/or the driver) that smoothes what would be aggressive gear grabbing. When the power is back to full, it's difficult to keep my head off the head restraint. Even crossing the finish line at 130 mph, this car is still accelerating very, very hard.
Braking commentsIncredibly hard pedal, zero dive un-fadeable brakes. The only difference in distance from run to run is attributable to the surface of the track.
Handling commentsSlalom: In the Porsche 911 tradition, the only way through a slalom course is with progressive throttle application -- otherwise (and even with maintenance throttle) the rear steps out. Luckily, the tires break free progressively, not abruptly. Best run is slow-in/fast-out to best utilize the LSD on exit -- and it works beautifully, rocketing through the finish line at W.O.T. Skid pad: Large discrepancy between clockwise and counterclockwise, e.g. with driver inboard, (CCW) the car would oversteer slightly and controllably. However, with driver outboard, the car would understeer. Either way, the steering is highly informative and weighted just right.
