Acceleration from the CTS wagon is adequate and nothing more. It does little to inspire the heart, soul or body. The engine isn't involving and there's little a driver can do to improve acceleration.
Respectable stopping distance. No fade. Feels only OK.
Skid pad: Stability control cannot be fully disabled and makes its presence known clearly on skid pad. Again, a good number but not such a fun one to earn. Slalom: Stability control calibrated well enough to truly stay out of the way in all but the stupidest situations. Chassis doesn't like midcorner bumps (cone 3) but still makes a good slalom number.
