Images of Mercedes' facelifted S63 and S65 AMG sedans

Executive limo accommodations, supercar power and sleeper-no-more looks are the key ingredients to Mercedes Benz's newly facelifted pair of S-Class AMG sedans. Photos leaked today reveal both the S63 and S65 AMG sedans in full - if somewhat low-resolution - detail.

Little information has been released, though much can be gleaned from the photos, accidentally unleashed by Mercedes' own German-language site. LED accents abound, with the high-tech illumination powering daytime running lights, fog lights and tail lights. Inside it's the usual array of fine wood, leather, high-grade plastics and reserved color combinations.

Expect the same engine underhood as the current cars, since this is just a mid-cycle freshening. That means the S63 will be cranking 518hp (386kW) from its 6.2L V8 mill, while the S65's 6.0L V12 will spin up to 604hp (450kW) and 738lb-ft (1,000Nm) of torque. All that twist necessitates use of a 5-speed automatic transmission instead of the 7-speed unit found in the S63.

More info and full high-res photos will come upon the cars' full reveal at the 2009 Shanghai Auto Show, which kicks off later this month, but pricing, features, and other elements are expected to remain the same as the currently offered model.
