Mercedes-Benz EQ Boost technology explained in simple terms

Since 2018, Mercedes-Benz has been promoting a technology that is called EQ Boost. Simply put, EQ Boost is designed to make all engine components more efficient, so that the engine delivers more power, but also better fuel efficiency.

Here's how it works.

Its nerve centre is an Integrated Starter Generator (ISG). This is at the heart of a the 48-volt mild hybrid system called the EQ Boost technology. The advantage of integrating the components is that rather than being separate from the engine, the ISG is permanently connected to the transmission. It is housed between the transmission and the engine itself.

If you're familiar with the work of the starter, the generator adds a differentiating element to the system. This one is in fact capable of recovering energy to charge the traditional battery, but also supports the 48-volt mild hybrid system and the traditional 12-volt system.

Then, since the electric unit is always on, it provides extra power to the combustion engine, up to 21 horsepower and 184 pound-feet of torque. It also provides the driver with more power at high rpm, which is more difficult for the combustion engine alone. Under certain conditions, the gasoline engine can come to a complete stop and allow the vehicle to run solely on electricity. This, you guessed it, promotes better fuel economy.

The EQ Boost system may seem complicated, but in reality, it simplifies the mechanics. For example, engines with EQ Boost technology have no belts and a more compact design.

In short, and as you can see, the advantages of this system are numerous, and they represent only part of what we will see in terms of technology in the coming years at Mercedes-Benz.
