Test Driver Ratings & Comments
Acceleration commentsCannot overcome rear tire grip for anything close to a launch with optimal tire spin. That said, the engine feels/sounds willing and free-revving. Upshifts occur at +/- 7,000 rpm in either D or DS mode. Fast and smooth shifts. Third gear is exceptionally tall and just enough to cross the quarter-mile finish line. Very consistent collection of runs because there's very little I could do to affect a different outcome.
Braking commentsMedium-firm pedal, little idle stroke and very powerful brakes. Virtually no ABS flutter/buzz with a slight lock-up at the very end. Excellent fade resistance and minimal dive or suspension wind-up.
Handling commentsSkid pad: I expected more grip, especially at the front. The understeer is not the tire-screeching type, but a gradual, quiet sort. Nearly identical times in either direction speaks to the car's excellent balance. Steering loads up early and heavily. Lifting throttle didn't produce yaw, but only muted the understeer. Slalom: Feels heavy and disinclined to change direction rapidly despite its numerically competitive results. Heavy steering, slow yaw response, and more roll than I expected from the FE3 suspension. At the limit, there's not much feel for what's happening beneath, but it's not threatening either. Understeer eventually creeps in and makes the car "late" for the next cone(s). Good, not great handling. Too bad about having to wrestle with the steering wheel. The CTS sedan doesn't feel this uncooperative.
