It's a sign of the times if we've ever seen one that Mercedes has chosen to debut its new flagship sedans at the Shanghai motor show this year. The German automaker has given the top-of-the-line S-Class a mild update for the 2010 model year, and has just released details and photos of the pair of AMG-tuned sport models at the peak of the range.
Like the rest of the line-up, the S63 AMG and S65 AMG get a new grille, LED lighting, revised front bumper and rear bumper with an integrated diffuser to help it stay glued to the road on those de-restricted Autobahns. The interior has likewise been updated, incorporating the full array of electronic systems to make driving these muscular luxury sedans a breeze. But it's under the hood where these two behemoths really shine: the S63 packs a 525-horsepower V8, while the S65's party piece is a twin-turbocharged V12 with over 600 horsepower. Both are aided by Mercedes' latest torque vectoring system to help get the giants around the corner. Although this is probably the last concern of someone buying a machine like either of these, but emissions and fuel consumption have been improved on both models by a meager 3%. Pricing has not yet been announced, but the previous models which these replace sold for approximately $130,000 and $200,000 respectively, so expect similar pricing on the 2010 versions, which you can view in the pair of image galleries below.
