Took the Kappa to a locally-well known area called Hocking Hills. Nice road but there were so much slow traffic (read motorcycles) it was difficult to develop triple-digit speed. Managed a couple bursts, but that was it. It didn't have the instant reaction of my LS6/7 or my M3's throttle response but once the turbo was on boil, it had no problem gaining speed. It reminded me why I gave up turbocharged 4-cyl engines about 8 years ago and went for V8s.
The Kappa handled nicely but I felt there was something substantial missing, maybe a set of Koni and a pair of big sway bars would bring in better feel. It nose-dived during braking and lifted its nose during acceleration a bit too much. It also rocked front to back when I wasn't too smooth with gear changes. It felt too compliant.
Downshifting was a bit tricky since during a throttle blip the engine speed didn't respond as quickly as the others; as the result RPM got hung up and the car jerked. Tried to find the right combination of amount of throttle jabs and time delay but I didn't get enough practice. Exhaust was very quiet; maybe that's part of the reason why I couldn't upshift smoothly. Wind noise with top down robbed the exhaust noise.
The ergonomics was ok. It didn't have the large blind spot of the CTS-V when trying to look around a corner (i.e. the area between the A-pillar and rear view mirror). I have learned to memorize ahead of time with the CTS-V but with the Kappa I could wait until I was almost on top of the apex. I still need to find a better driving position as I got fatigued a bit quicker. I probably looked pretty dorky too trying to rest my elbow on the window sill

It was a nice test drive session, as I got quite a bit of insights of the car. My wife agreed that it needed to be stiffer and louder. The problem will be deciding what part the next budget goes to
