Year to Year Changes


2004 Mercedes-Benz SL-Class: A 12-cylinder SL600 flagship model debuted for 2004, along with a seven-speed automatic transmission. Installed only in the SL500, the seven-speed was an industry first. During up and down shifts, it could skip gears for increased efficiency. Other models retained Mercedes' five-speed automatic. All models were now pre-wired for optional dealer-installed satellite radio. The Keyless Go option now took its signal from a keyboard instead of a pass card.
2005 Mercedes-Benz SL-Class: For 2005, the navigation system and center console were revised. A new limited-production SL65 AMG model was launched, with a 604-horsepower, twin-turbo V-12 engine. In addition to specific styling touches, the SL65 AMG got bigger brakes and 19-inch wheels. The revamped console included an updated version of Mercedes' COMAND video control for navigation, audio, and climate functions.
2006 Mercedes-Benz SL-Class: Keyless Go, a keyless-entry and starting system, became standard on SL600 and SL65 models, but remained optional for the SL500 and SL55. Run-flat tires now were available for SL500/600 models. Satellite radio joined the options list. The high-performance SL55 AMG could be equipped with a $14,000 AMG Performance Package that included exclusive interior trim and a 186-mph top-speed governor (others were limited to 155 mph).
2007 Mercedes-Benz SL-Class: New for 2007 was the SL550. It replaced the SL500 and had a 382-hp V8 vs. 302 hp.
2008 Mercedes-Benz SL-Class: The 2008 Mercedes-Benz SL-Class got no major changes.
