Status: 02 / 2013 – 4 Introduction of the New A-Class AMG with Engine M 133 | Model Series 176 AMG Preface Dear Reader, This Introduction into Service manual presents the A 45 AMG 4MATIC in model series 176. The purpose of this brochure is to acquaint you with the tech- nical highlights of this new vehicle in advance of its market launch. This brochure is intended to provide information for people employed in service or maintenance and repair as well as for aftersales staff. It is assumed here that the reader is already familiar with the Mercedes-Benz/AMG engines currently on the market. This Introduction into Service manual is not intended as an aid for repairs or for the diagnosis of technical problems. For such needs, more extensive information is available in the Workshop Information System (WIS) and Xentry Diagnostics. WIS is updated continuously. Therefore, the information available there reflects the latest technical status of our ve- hicles and major assemblies. This Introduction into Service manual presents initial infor- mation relating to the A 45 AMG 4MATIC in model series 176 and, as such, is not stored in WIS. The contents of this brochure are not updated. No provision is made for supplements. We will publicize modifications and new features in the re- levant WIS documents. The information presented in this Introduction into Service manual may therefore differ from the more up-to-date information found in WIS. All information relating to technical data is valid as of the copy deadline in February 2013 and may therefore differ from the current production configuration.

Status: 02 / 2013 – 5 Introduction of the New A-Class AMG with Engine M 133 | Model Series 176 AMG Brief description Overview Vehicle concept/highlights The powerful top-of-the-range new A-Class from Mercedes- Benz ushers in a new era for the performance brand AMG. For the first time in the 45 years of its corporate history, AMG will offer a fascinating high-performance vehicle in the compact class. The new A 45 AMG 4MATIC stand together with other, future high-performance compact cars for exclusive dynamism and the “AMG Performance 50” growth strategy. Mercedes-AMG GmbH introduces the first 4-cylinder gasoline engine of its own to feature direct injection and turbochar- ging. The engine sets new standards in its displacement class and will be launched on the modular front-wheel-drive architecture platform (MFA) with the W 176. In terms of power and consumption, the M 133 raises the bar and assumes pole position among its competition. From its 2.0 l displacement, the M 133 develops a maximum output of 265 kW and a maximum torque of 450 Nm. The high-tech package tailored by Mercedes-AMG is a prere- quisite for emotional power delivery. As already used in the M 157, AMG again employs the advantages of spray-guided gasoline direct injection with piezo injectors in the M133. The greater thermodynamic efficiency of this technology provides better fuel economy and leads to lower exhaust emissions. Optimum power transmission is ensured by the AMG SPEEDSHIFT DCT 7-speed sport transmission with dual clutch technology and the performance-oriented all-wheel drive. The best preconditions for high cornering speeds and remarkably nimble handling are provided by the AMG sports suspension with independently developed front and rear axles, electromechanical AMG Sport speed-sensitive power steering, the AMG high-performance brake system and the 3-stage ESP® with Sport Handling Mode. Other highlights are the sand-cast all-aluminum crankcase with NANOSLIDE barrel technology, air/water intercooling, alternator management and the ECO start/stop function. b Note Further information on the electrical systems in model series 176 (e.g. function descriptions and locations of electrical components) is available in the Workshop Information System (WIS) under Basic Knowledge/ Functions (GF). – This printout will not be recorded by the update service.
