Its centrepiece is the electrified 3.0-litre engine featuring twin-turbocharging and an electric auxiliary compressor. The 6-cylinder in-line engine generates 320 kW (435 hp) and delivers maximum torque of 520 Nm. Its EQ Boost starter generator briefly provides an additional 16 kW of output plus 250 Nm of torque and additionally feeds the 48 V on-board electrical system.
The EQ Boost starter-alternator combines a starter motor and alternator in a powerful electric motor and is fitted between the engine and transmission. This innovation as well as the intelligent charging via an electric auxiliary compressor and an exhaust gas turbocharger all have the same goal: to enhance the hallmark AMG performance and driving dynamics, but also to reduce fuel consumption and emissions. And this move has been a successful one: The GLE 53 4MATIC+ accelerates from zero to 100 km/h in just 5.3 seconds and achieves an electronically limited speed of 250 km/h.
The electric auxiliary compressor builds up a high level of boost pressure without any delays until the big exhaust gas turbocharger kicks in. As a result the 3.0-litre engine reacts extremely spontaneously and provides a dynamic response without turbo lag. An additional bonus is the high level of refinement of the six-cylinder in-line engine.
But the EQ Boost starter-alternator can do even more. It also provides the 48 V on-board electrical system with electricity. The conventional 12 V electrical system is likewise supplied from the new network – by means of a DC/DC converter. The 48 V battery increases the overall battery capacity in the vehicle, which allows supplying more electrical energy. 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 12 V system supplies power to consumers such as lights, cockpit, infotainment displays and control units.
The EQ Boost starter generator is a key component of the 48 V 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 16 kW of output and 250 Nm of torque, energy recovery, 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 particulate filter is the only part of the emission control system that is under the floor.
A special acoustic experience comes courtesy of the optional, selectable AMG Performance exhaust system. The variable adjustable exhaust flaps give the option to change the sound of the vehicle at the press of a button. Depending on the drive program, the sound characteristics change from unobtrusive comfort through to maximum emotive appeal.
The AMG SPEEDSHIFT TCT 9-speed automatic transmission (TCT = Torque-Clutch Transmission) ensures emotional gear shifting with extremely short shift times. It is optimally tuned to the engine and promises agile pulling off typical of AMG as well as speedy shifting – regardless of an automatic or manual transmission via the steering wheel shift paddles. Upshifts or downshifts are implemented instantly. Especially in the “Sport+” and in manual driving modes, the transmission is very responsive. Multiple downshifting enables fast bursts of speed, while the double-clutching function makes shift operations acoustically more emotional.
