Test Driver Ratings & Comments
Acceleration commentsOnce on boost the C250's acceleration is adequate, but it still lacks the punch of the Audi and BMW. Also, the transmission feels behind the times. No shift paddles. No rev-matching. Not in the game.
Braking ratingGood
Braking commentsGood feel and performance (beats 328i). Also, more consistent than BMW.
Handling ratingGood
Handling commentsNon-defeat ESC makes its presence known in both tests. Steering doesn't build confidence as limits approach. Balance, too, isn't spectacular around skid pad. Slalom: Snakes between the cones with good stability (thanks, ESC), but doesn't inspire me to push harder once ESC activates. Safe and consistent and easy, but less "sport" sedan than the others.
