The Mercedes SL55 AMGis a sinuous, sensuous roadster with dramatic styling and a major-league price tag. Slide into the cockpit, belt up, press the button on the console and, 16 seconds later, its retractable power steel roof changes it from the open-air fun of a convertible to the quiet comfort of a luxury coupe. The SL55 AMG is packed with every bit of automotive technology that Mercedes has perfected over the past dozen years, and that's a lot of technology. It does everything well.

This SL55 AMG version is brimming with incredible levels of performance. The SL55 AMG uses a newly developed, hand-built, 5.5-liter supercharged engine with more than 493 horsepower to catapult itself from 0 to 60 mph in just 4.4 seconds, making it the fastest production Mercedes-Benz roadster ever. The SL55 AMG comes with racing-derived braking power. Its immense 14-inch vented brake discs and calipers are engineered with the industry's first electronic braking system, stopping the SL55 AMG with racecar-like ability. Similarly, the SL55 AMG uses a further evolution of the ABC active suspension to imbue the car with cat-like reflexes while simultaneously offering ride comfort that rivals any of its competition.
