Mercedes-Benz Mild Hybrid Overview

Mercedes-Benz has been putting a long of energy into electrification recently, and the Mercedes-EQ lineup is an incredible testament to that. But that’s not all that’s happening. Mild hybrid technology, formerly known as EQ Boost, has been finding its way onto a lot of the gas-powered Mercedes-Benz vehicles. This is some very good news, but it might not be totally clear why that is, so Mercedes-Benz of Easton has put together a helpful guide.

How Does Mercedes-Benz Mild Hybrid Technology Work?
There is really only one piece that you need to understand to know how the Mercedes-Benz mild hybrid system works. That is the ISG, or Integrated Starter Generator. This is integrated into the transmission and connects directly to the driveshaft. Engines equipped with an ISG actually won’t have a separate starter or alternator, as the ISG can perform both functions. It can start the engine, and provide a power boost when needed. And then while coasting or decelerating it can generate electricity that is stored in a battery, the only other major component of the mild hybrid system.
The Benefits Of A Mild Hybrid System
Improved Performance
Gasoline engines and electric motors have different strengths when it comes to powering a vehicle, and a mild hybrid system is an excellent way to make both work for you. Gasoline engines need to rev up a bit before they hit peak torque, but electric motors don’t. So the ISG can give you a boost at lower RPMs, before you reach higher RPMs where the higher horsepower rating of the gas engine becomes more important.
Improved Fuel Economy Without Compromise
The word “hybrid” has an unfortunate tendency to scare a lot of people off, since quite a lot of early hybrids were punishingly dull to drive. But the Mercedes-Benz mild hybrid system doesn’t ask you to sacrifice performance. Fuel economy is improved, but so is performance.
Electrification Without Anxiety
Many people can’t wait to park an electric vehicle in the garage, but fully electric vehicles aren’t quite practical for everyone yet. For those people, a mild hybrid system is a good way to get some electrification without needing to plug your vehicle in somewhere overnight.
