Test Driver Ratings & Comments

Acceleration commentsWith traction control on, the C63 initially stumbles off the line, then rockets down the strip. Engaging ESP Sport allows just enough useful wheelspin to subtract 0.6 second to 60 mph. Auto upshifts are very fast right at redline.
Braking ratingVery Good
Braking commentsABS pulsing was evident as the system hunted for traction. Pedal effort is moderately firm and dive was near zero. Feel is a little vague and changes with each stop. Hard to judge fade resistance here, but we did experience some while lapping at the racetrack.
Handling ratingVery Good
Handling commentsSkid pad: Moderate understeer at the limit gets worse if pushed further. Steering is reasonably communicative but not benchmark-good. Slalom: Until the slalom was dusted off and "groomed," the C63 felt "pushy-loose." It would understeer at one cone then oversteer at the next. Also, unless the road surface is billiard-table smooth, the C63 never feels composed. A slight dip at cone #3 sends the C63 wide for the next gate. There might be more in it, not here, not today. Steering feel is marginally good, but quite precise. Seats are purpose-built for slalom testing.
