While obviously a head turner, this tanzanite blue metallic SL55, with gray leather interior from AMG (Mercedes’ performance division) is all about power, speed and performance, and… it… is… fast. 55 percent more powerful than the SL. The SL55 overlays a level of performance that raises it to the status of true supercar capability. Mercedes’ claimed 4.6-second blast to 60 mph—a staggering 1.5 seconds faster than the SL500—can’t convey the difference in acceleration, or character, between the two sports cars. The SL55 AMG feels dramatically quicker, as the anticipated numbers indicate. In the 15 seconds, it should take the SL55 to reach 125 mph, the SL500 would be at 105 mph.The secret, achieved by an IHI belt-driven screw supercharger that spins at 23,000 rpm to a maximum pressure of 11.6 psi, is mountains of torque. At a meager 1500 rpm, the SL55 delivers 369 pound-feet, already 30 pound-feet above the SL500’s peak. It achieves a peak 516 pound-feet across a plateau from 2650 rpm to 4500. This is instant performance gratification, the breed of responsive, accessible power that, working smoothly with the five-speed automatic transmission, endows the SL55 with instantaneous, horizon-catching acceleration. Mercedes’ ESP stability control keeps it in check to the accompaniment of a flashing warning light. Switch off ESP so there’s no reduction in engine power when a rear wheel loses traction, and tire-smoking starts are only a throttle tickle away. Yet even on damp roads, the SL55 has massive traction.
