A multi-spark ignition system with 12 twin ignition coils also makes for smoother running, and it works together with a new engine-management system and optimized cylinder heads to provide more-effective combustion. The outcome is fewer exhaust emissions, also in large part due to an improved catalytic converter.

A redeveloped AMG sport exhaust system incorporates a modified pipe layout for improved flow coupled with a weight reduction of seven pounds from reduced wall thickness.

While the exterior of the car doesn’t deviate significantly from the look of its SL and SL63 AMG siblings, the interior pretty much has all the bell and whistles included. The list of standard equipment is staggering, including items such as the Parktronic parking assistant, Bang & Olufsen premium sound, carbon-fiber trim, Comand infotainment with 40 GB hard-drive and GPS navigation, Magic Vision Control retractable roof and automatic pop-up rollover protection for driver and passenger.

Some of the options worth mentioning include a carbon-ceramic brake package, some carbon-fiber aero mods and an AMG media package. There’s also a unique color palette with several options available through Mercedes’ special “design” label. These include the matte paint finishes designo Magno Cashmere White and designo Magno Alanite Grey, and the metallic paints designo Mocha Black and designo Graphite.

While first sales of the 2013 Mercedes-Benz SL65 AMG don't start until November, the regular SL550 model goes on sale in May and the slightly tamer SL63 AMG hits showrooms this July.
