Transition to Inline 6 Engines

Mercedes-Benz embraced a significant shift in their engineering approach by transitioning to inline 6 engines. Known for their straight-six configuration, inline 6 engines provide a smoother operation due to their natural balance. The latest inline 6 models, part of the modular engine family, feature 3.0-liter displacement and a 48-volt electrical system, which includes EQ Boost, a mild-hybrid technology. This innovation not only increases power output to 362 horsepower but also enhances fuel efficiency.

The design of these inline 6 engines reduces mechanical complexity, potentially lowering manufacturing costs. Moreover, these engines are tailored to meet stricter emission standards, aligning with global environmental concerns.
