Powertrain and Engine Technology

At the heart of the 2025 S450 is a sophisticated 3.0-liter inline-six engine equipped with a 48-volt mild-hybrid system and EQ Boost technology. This powertrain combines traditional internal combustion with electric assistance to deliver smooth power delivery and improved efficiency.

• Torque: 500 Nm of torque across a broad rpm range.
• Mild-Hybrid Assistance: Adds a small electric boost, reducing turbo lag and improving fuel economy.

This combination ensures the S450 is both quick and refined — delivering strong acceleration while keeping vibrations and noise exceptionally low.
