This S-Class AMG is a Performer with a Purpose

Power, performance, luxury, and…going green? Yes, you read that correctly. The 2011 Mercedes-Benz S63 AMG was born out of an ambitious goal. Dubbed AMG Performance 2015, the project was designed to “continually reduce the fuel consumption and emissions of new models…while at the same time enhancing the core brand value of performance,” according to AMG then-chairman Ola Kallenius. Fun Fact: For the S63, that performance included being able to hit 60 mph in 4.4 seconds.

While the S63 boasts 536 HP and 590 lb. ft. of torque, it also has a 25-percent reduction in fuel consumption, resulting in lower emissions. In part, this was achieved by reducing the V8 engine from 6.3L (while still retaining the “63” badging) to 5.5L, and by adding a brace of turbochargers. The engine also marked the first time direct gas injection was included on an AMG power unit. Technological refinements on the S63 included spray-guided combustion and piezo-electric injectors.

Spelling It Out

AMG is the Mercedes-Benz division that produces performance autos. Named after three standout engineers in the company’s history, it’s short for Aufecht, Melcher, and Großaspach. Also, the S63 is part of the Mercedes-Benz S-Class. The S comes from sonderklasse, which is German for special class.

A Model of Efficiency

As part of AMG’s focus on efficiency, the S63’s generator management made use of previously wasted kinetic energy to charge the battery. Additionally, AMG’s multi-clutch technology (MCT) seven-speed transmission – already part of the SL63 and E63 models – made its debut in the S63.

A start/stop function came standard with the S63. That function registered the resting position of all eight pistons. It then restarted the engine by injecting fuel into the combustion chamber of the cylinder with the most favorable piston position.
