Pokey bottom-end, so-so midrange, but lots of horsepower in the upper revs. Very quick shifts at WOT, and no manual gate to try (D, D3, etc) on the PRNDL.
Adequate first stop, then pretty dramatic though linear increase in stopping distances thereafter. Strange pedal sensation that felt almost like completely cooked brakes from first stop to last (e.g. no ABS pulse, no tire noise).
Skid pad: A novice would be hard-pressed to discover on his own that this was electric-assist power steering. Very good feel and weight that feels natural and hydraulic. Low limits are audible from squealing tires. With stability control on, you don't hear the tires, but the lap is obviously slower. Slalom: Wow, so much more body roll than I would have expected. It feels like a much larger car because it requires a lot of time to transition from one cone to the next. Still, the steering feels so good and it is so precise that it feels like the car could/should go quicker than it does -- I guess that's what the Si model is for. With ESC on, it was much more conservative and thus slower than it needs to be.
