Mercedes-Benz has always been a hallmark of luxury and performance. With the latest addition to their engine lineup, the German automaker shows no signs of slowing down. The new inline-six engine marks a return to a classic configuration for Mercedes-Benz, promising an enticing combination of power and efficiency. Here are the key things you need to know about this exciting development.

1. Return to Inline-Six Roots: After almost two decades of absence from the Mercedes-Benz lineup, the inline-six engine is making a triumphant comeback. The new M256 inline-six engine replaces the previous V6 engines and marks a return to Mercedes-Benz’s tradition of straight-six engines.

2. Efficient and Powerful: The new inline-six engine offers increased efficiency and performance due to its 3.0-liter displacement, mild hybrid system, and turbocharging capabilities.

3. Innovative 48-volt Mild Hybrid System: A key innovation in the M256 is its 48-volt mild hybrid system called EQ Boost. The integrated starter-alternator (ISG) serves numerous functions, including aiding acceleration, enhancing efficiency, and contributing to the engine’s start-stop functionality.

4. Electric Turbocharging: Unlike conventional turbochargers that rely on exhaust gases to drive their compressors, the M256 uses an electric auxiliary compressor (eZV). This electric turbocharger delivers instant boost pressure with virtually no turbo lag.

5. Seamless Integration: Mercedes-Benz has designed this engine as a modular unit so it can be easily integrated with other components in their vehicles. This means customers can enjoy the benefits of this advanced powertrain without sacrificing compatibility with other features or systems within their cars.

6. Reduced Emissions: The commitment to cleaner combustion is evident in the design of the M256. It includes innovative particulate filters and exhaust after-treatments that help reduce emissions while providing optimal performance.

7. Availability: Initially, the M256 engine debuted in the Mercedes-Benz CLS450 and S450 models. It has since been expanded to other model lines, including the E-Class and GLE-Class.

In conclusion, the Mercedes-Benz M256 inline-six engine marks an important step forward in automotive technology by offering greater efficiency and power in a compact, environmentally friendly package. The return to a straight-six configuration, the use of a 48-volt hybrid system, and the advanced electric turbocharging technology make this engine a worthy addition to the storied history of Mercedes-Benz.
