STOCKACH, Germany — Although 525 horsepower seems like plenty for the Mercedes-Benz SL63 AMG, tuner Kicherer begs to differ with its latest package.The 6.2-liter V8 engine has been upgraded to 560 hp and 495 pound-feet of torque in Kicherer's capable hands. That means a 0-60-mph time of less than 4.3 seconds and an electronically limited top speed of 199 mph.The complete all-carbon-fiber aerodynamic package includes a new front bumper that reduces lift on the axle. All exterior pieces are made of carbon fiber. A rear diffuser, shaded rear lights and a trunk lid spoiler are also part of the kit, and a set of 20-inch RS-1 aluminum wheels add polish to the exterior appearance.Inside, there's a Formula 1 style steering wheel, carbon-fiber trim and extra instrumentation.Pricing starts at the equivalent of $32,116 for the package.What this means to you: Kicherer helps the SL breach supercar territory with all that extra power. — Mike Lysaght, Correspondent
