The SL underwent a facelift in 2006, and was unveiled at the Geneva Motor Show.

Changes include new engines for SL 350 and SL 500 (called SL 550 in North America), with improved performance on SL 55 AMG and SL 600, as well as a new top-of-the-line SL 65 AMG.
ABC (Active Body Control) was improved to reduce body movements in dynamic driving by up to 60%, standard on all models except the SL 350.
The new engines were mated to a new 7-speed 7G-Tronic automatic, with a Sport option to allow shifting to be performed up to 30% faster in manual "M" mode, and with added steering-wheel shift paddles.

Exterior styling changes include a new bumper with three large cooling air intakes and a more pronounced V-shape as well as fog lamps with chrome surrounds, new light-alloy wheels, new rear light.
Interior changes include softer leather upholstery, new interior colours, high-quality metal door sills with Mercedes-Benz lettering and embossed aluminium trim elements, removable luggage cover, optional remote boot-lid release.
The roof opening mechanism was also revised, reducing the opening time from 20-seconds to 16-seconds.
