Mercedes-Benz SL600 Overview

The SL-Class roadster is offered in four models: SL550, SL600, an all-new SL63 AMG and the SL65 AMG. The SL550 is powered by a 382-hp 5.5-liter V8 engine, mated to a seven-speed automatic transmission. The SL600 is outfitted with a 510-hp 5.5-liter bi-turbo V12, while the SL65's larger 6.0-liter bi-turbo V12 generates 604 horsepower and a formidable 738 pound-feet of torque; both engines are paired with a five-speed automatic transmission with shift paddles. The SL63 AMG boasts a hand-built 518-hp 6.3-liter V8, as well as a new seven-speed MCT (multi-clutch technology) transmission not found in any other Mercedes model. The SL65 AMG Black Series coupe employs the same hand-built 6.0-liter bi-turbo V12 engine found in the roadster, modified to generate 661 horsepower. It is matched to a revised five-speed automatic transmission, boasting AMG SpeedShift Plus with four driver-selectable modes; an AMG performance steering wheel is outfitted with aluminum paddles for manual shifting. All SL-Class roadster models are equipped with a power retractable hardtop, adaptive suspension with Active Body Control (ABC), heated leather seats, automatic climate control, satellite radio and a voice-activated navigation system. Elements exclusive to the SL65 AMG Black Series include a uniquely calibrated driver-adjustable sport suspension, a rear spoiler with automatic speed-dependent deployment, and staggered forged alloy wheels: 19 x 9.5-inch up front and 20 x 11.5-inch at the rear. A three-stage electronic stability program (ESP) with sport mode, along with ultra high-performance tires and massive composite brakes, enhances both handling and safety aspects. Other standard safety features include four-wheel anti-lock disc brakes, stability and traction control, front, side and driver knee airbags, and an automatically deployable rollover bar (roadster only).

For 2009, the Mercedes-Benz SL-Class receives a facelift, with all models now sporting more aggressive AMG body styling, redesigned Bi-Xenon headlamps with Active Curve Illumination, and a new multimedia interface with DVD, iPod and Bluetooth capabilities. Additionally, an all-new SL63 AMG model, with unique styling and technologies, replaces the previous year's SL55 AMG, and the limited-edition SL65 AMG Black Series coupe makes its debut. Based on a modified and lightened version of the SL65 AMG roadster, it replaces the power hardtop with a fixed carbon fiber roof; other carbon fiber elements, such as the hood, trunk lid, front and rear aprons and wider front fenders, lend a dramatic appearance, as well as additional weight savings.
