"Check the motivational specs: 493 horsepower at 6100 rpm, 516 pound-feet of torque manifesting itself along a wonderfully flat curve from 2650 to 4500 rpm. It's the most potent Benz ever offered in North America, according to the manufacturer, and also the quickest factory Benz we've ever tested: 0 to 60 in 4.5 seconds, 0 to 100 in 10.9, the quarter-mile in 13 seconds flat at 110 mph. The hand-assembled AMG version is stroked from 84 millimeters to 92, increasing displacement from 4966cc to 5439, and the forged aluminum pistons drop the compression ratio from 10.0:1 to 9:0:1, an anti-detonation measure. There are heavy-duty bearings with cross-bolted mains at the bottom end, plus a new sump and a more powerful oil pump. Top-end mods include double valve springs, reprofiled cams, and bigger intake and exhaust plumbing. The supercharged eight feeds its power to a five-speed automatic transmission that incorporates an updated edition of the Mercedes SpeedShift manumatic. This one offers three modes—normal, winter, and manual. Its basic function is essentially the same as Chrysler's AutoStick: Waggle the lever, and you can shift up or down, or operate in full automatic mode. Unlike AutoStick, the manual mode allows shifting via rocker switches mounted on the backs of the steering-wheel spokes. And unlike the other modes, selecting manual allows the driver to hold a particular gear right up to the rev limiter. Which brings us to this car's all-around dynamics. Mercedes refers to its "catlike handling reflexes," which is true—if you envision a cat the size of a Siberian tiger. The key to the SL55's level cornering attitudes is the corporate Active Body Control electro-mechano-hydraulic almost-active suspension, recalibrated in this application for firmer responses without compromising ride quality. Although this sophisticated system can't erase weight—it's always there, always tangible—it manages that weight amazingly well, whether the car is clawing the pavement in a fast sweeper or unkinking a set of switchbacks. This kind of activity is abetted by the SL55's speed-sensitive rack-and-pinion steering, which seems to deliver a little more tactile information than the SL500's system, and by the availability of all that torque for blasting off corners. car and driver" 64000 miles CLEAN CARFAX HEATED SEATS VENTILATED SEATS MASSAGE SEATS NAVIGATION PREMIUM WHEELS STEERING WHEEL SHIFT BUTTONS
