Test Driver Ratings & Comments
Acceleration commentsEven default mode in Drive, the SLS is deceptively quick and obviously fast. Speed comes on gradually then piles on endlessly. Once "RS" is selected, the car rolls slightly off the line, allows slight wheelspin and it cuts 3/10 from 0-60 and about as much from the quarter-mile time (trap remains the same). Upshifts in S+ are very quick but not harsh at all. Manual mode offers shift lights, but proved slower. Wheelspin with ESC off was virtually impossible.
Braking ratingExcellent
Braking commentsImmediate bite and crazy effectiveness. Flat, short, consistent, straight, amazing. Pedal effort remained moderate-to-high, but not brutal.
Handling ratingVery Good
Handling commentsSkid pad: ESC off and resolute understeer sets in -- lifting the throttle diminishes it, but the car doesn't rotate as a result. With ESC Sport, the understeer goes away and I could feel the rear stepping out slightly all the way around. Funny thing is, I couldn't detect/feel any brake application. Steering is magical, delicate and informative. Excellent weight and response. Slalom: This is a tough car to slalom -- it's obviously tuned to drive/steer from the rear and you must enter slowly and gradually squeeze the throttle to keep the rear planted. Otherwise, it gets loose, I catch it, but find myself late at the next cone. With ESC Sport, however, the car feels reined in and electronically limited (mostly closing throttle). The result is you can't steer it with throttle.
