What is a Mild Hybrid?

A mild hybrid is a type of hybrid vehicle that uses a small electric motor to assist the gasoline engine. Unlike a full hybrid or plug-in hybrid, a mild hybrid cannot run on electric power alone. Instead, the electric motor provides extra power during acceleration, improves fuel economy, and allows for smoother start-stop operation.
How Does it Work?
The mild hybrid system in Mercedes-Benz vehicles typically includes a 48-volt electrical system and an integrated starter-generator (ISG). Here’s a breakdown of how it works:
- Energy Recuperation: When braking or decelerating, the ISG captures kinetic energy and converts it into electricity. This electricity is stored in a small battery.
- Boost Assistance: During acceleration, the ISG provides an extra boost of power to the engine. This reduces the load on the engine, improving fuel efficiency and performance.
- Start-Stop System: The ISG enables a smoother and faster start-stop operation. When the car comes to a stop, the engine shuts off to save fuel. When you’re ready to go, the ISG quickly and quietly restarts the engine.
- Coasting: At higher speeds, the engine can shut off completely and the car can “coast” using the electric motor, further saving fuel.
Benefits of Mercedes Mild Hybrid Models

There are several advantages to choosing a Mercedes-Benz mild hybrid. These benefits make the driving experience more enjoyable and efficient.
- Improved Fuel Economy: The electric motor assists the engine, reducing fuel consumption, especially in city driving.
- Enhanced Performance: The extra boost from the electric motor provides quicker acceleration and a more responsive driving experience.
- Smoother Start-Stop: The start-stop system is less noticeable and more refined than traditional systems, offering a seamless transition.
- Reduced Emissions: Lower fuel consumption translates to reduced greenhouse gas emissions, contributing to a cleaner environment.
- Increased Comfort: The electric motor helps smooth out the engine’s operation, resulting in a quieter and more comfortable ride.
