Mercedes-AMG 53-Series CLS, E-Class Coupe and Cabriolet
High Torque Without Lag
Supported by the EQ Boost starter-alternator when moving off, the electric auxiliary compressor builds up a high charge pressure without any delay, for a faster increase in torque for acceleration until the large exhaust gas turbocharger is deployed. As a result the 3.0-liter engine reacts extremely spontaneously and provides a highly dynamic response without turbo lag. An additional bonus is the high level of refinement of the six-cylinder in-line engine.
Paving the Way for Hybrid Functions: 48V On-Board Electrical System
The power for the 48V on-board electrical system is generated by the EQ Boost starter-alternator. The conventional 12 V network is likewise supplied from the new network – using a DC/DC converter. Thanks to the 48V battery, the overall battery capacity in the vehicle is increased, enabling more electrical energy to be made available – and therefore also allowing innovative functions to be introduced, for example. The 48 V on-board electrical system is therefore paving the way for further hybridization. An additional advantage: the same power requires only a quarter of the current of a conventional system. The result is that the wiring can be thinner and therefore lighter, which indirectly contributes to saving fuel. The existing 12V system supplies power to consumers such as lights, cockpit, infotainment displays and control units.
Hybrid Functions Thanks to EQ Boost Starter-Alternator
The EQ Boost starter-alternator is a key component of the 48V system and not only serves as an alternator, but is also responsible for hybrid functions. This allows fuel savings that were previously reserved for high-voltage hybrid technology. For the first time, the EQ Boost starter-alternator is also responsible for idle speed control.
The hybrid functions include boost with 21 hp of output and 184 lb-ft of torque, recuperation, shifting of the load point, gliding mode and the virtually imperceptible restarting of the engine with the start/stop function.
Because the belt drive for ancillary components on the front edge of the engine is omitted, the installation length of the new six-cylinder engine is also significantly reduced compared with conventional six-cylinder engines. This creates space for an exhaust gas aftertreatment system mounted near the engine, which is therefore particularly efficient. The standard-fit particulate filter is the only part of the exhaust system that is under the floor.
Exterior: Twin-Blade Radiator Grille and Round Twin Tailpipe Trim Elements
Visually, the new 53-series models have a distinctive unique look. A distinctive feature common to the models is the twin-blade radiator grille in silver chrome, previously reserved for the V8 AMG models. Instead of the diamond radiator grille with individual pins, the grille in front of the central radiator now features a black lattice pattern.
The front bumper in an A-wing design is equipped with a front splitter in silver chrome. The outer air intakes have two horizontal fins in silver chrome. AMG-specific side sill panels lend the 53-series models a more dynamic silhouette.
When viewed from the rear, it is not just the redesigned rear bumper that stands out, but also the classic, round twin tailpipe trim elements in high-gloss chrome. As a result this provides for better air flow around the wheel arches. The lip spoiler on the trunk lid is painted in the body color, but is also optionally available in carbon-fiber.
