Tester's Comments:
Acceleration: With stability/traction off, there's still some electronic management of A) allowable revs at a standstill and B) power/torque being made in the engine. Result is bogging launch with reduced power then a rush of power when it comes back online. I believe the electronics are keeping mechanical parts from
breaking. Also, the tach needle is slow, so the shift light is critical to
not hitting the rev limiter. Finally, it feels as if there is a pretty
massive torque reduction between each upshift.
Braking:
Incredibly hard pedal, zero dive un-fadeable brakes. The only difference in distance from run to run is attributable to the surface of the track.
Slalom: 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 counter-clockwise 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.
