Test Driver Ratings & Comments

Acceleration commentsEasy to break tires loose with ESP off, and it doesn't seem to hurt acceleration much. Quick upshifts are smooth and at redline. Auto upshift in temporary "manual" mode.
Braking ratingAverage
Braking commentsGravelly tire noises indicate all-season level of grip. PreSafe tightens belts. Good fade resistance but poor stopping distance for an E550 "Sport." Excellent feel otherwise. Pedal got a little soft after five stops.
Handling ratingGood
Handling comments(Skid pad) ESP not truly off; in fact, it's not much different either way. Steering remains on the light side and offers little feel. (Slalom) Doesn't like to be tossed around -- prefers as little upset as possible. Pushed too hard, it's "pushy-loose." Kept tidy to the cones, it feels much more composed. Steering is fine and precise-feeling. Good in transitions.
