U.S. spec Mercedes SL facelift and SL63 detailsEnlarge Photo
Power levels are unchanged for the big-cube models but both engines get a slight bump in fuel economy. The 5.5L V8 still musters a healthy 388hp while the V12 in the SL600 dishes out 517hp thanks to its pair of turbos. The SL63, meanwhile, will get the venerable 525hp 6.3L V8 engine and the AMG speedshift seven-speed transmission. Other features include a unique front bonnet, custom bodykit, darkened bi-xenon headlamps and taillights, and 19in light-alloy wheels in a new triple-spoke design.
Like European models, U.S. spec cars get the new Airscarf heating system, which is optional on SL550 models and standard on the SL600 and SL65. An updated COMAND system with a 6.5in screen and 4GB hard-drive also features and is fully compatible with iPods, USB sticks, and memory cards.
The car will officially go on sale Stateside after making its local debut at the New York Auto Show in April.
