Test Driver Ratings & Comments

Acceleration commentsCompared to the 3.0 CXL, there's only a little more snap or sizzle from the CXS's 3.6-liter V6. Again, shifts are exceptionally smooth and occur at what we assume is a 6,500-rpm redline (none evident on tach). Quiet and confident but not at all what we'd call thrilling.
Braking ratingGood
Braking commentsPedal has some idle stroke, but the brakes themselves feel strong. Despite an identical 127-foot best stop, there's a little more fade on the CXS than on the CXL where this car's distances grew by about 5 feet from first to fourth stop. No ABS flutter or hum and dead straight.
Handling ratingGood
Handling commentsSkid pad: Appropriate effort/build-up from steering wheel. Easy to find the mild understeer at the limit. Good balance so I could easily alter the course with the throttle. ESP is rather conservatively tuned here, resulting in both brake application and throttle closure. Slalom: This CXS doesn't feel as crisp as the CXL did, but it ultimately makes the same handling numbers. The differences are: turn-in isn't as quick, it takes more time to take a set, and I had more difficulty placing the car very near the cones without hitting them. The stability system is well tuned to approach limits with minimal intrusion. All handling tests in Sport mode.
