The Mercedes-Benz Maybach S550 was a variant of the W222 S-Class Sedan that was introduced for the 2015 model year. The Maybach S550 represented the very highest level of luxury over the already luxurious standard S550. These luxury sedans were powered by Mercedes' M278 DE 46 AL engine, which was a 4.5L twin-turbo V8 that had an output of 449hp and 516lb ft of torque. Drive from the engine was sent to the rear wheels via a 9 speed automatic transmission.
