Mercedes-Benz has said that it will further expand the GLE model range with the introduction of the MHEV GLE 580. At the heart of the GLE 580 is an electrified V8 biturbo gasoline engine with a 48V onboard electrical system and integrated starter generator (ISG). This offers an output of 489ps and 700Nm of torque.
In addition, the GLE 580 is capable of producing an extra 250Nm of torque and 21ps through EQ Boost over short periods. The ISG is responsible for hybrid functions such as EQ Boost and energy recuperation. The ISG also eliminates the need for a belt drive for ancillary components at the front of the engine, which reduces its overall length.
The 48V onboard electrical system serves high power consumers, such as the water pump and air conditioning compressor, as well as the ISG, which also supplies energy to the battery by means of efficient energy recuperation.
