Overview
The Mercedes-Benz M271 engine is a robust and technologically advanced petrol powertrain designed for performance, efficiency, and reliability across a wide range of Mercedes-Benz vehicles. Produced from 2002 to 2015, this 1.6L to 1.8L inline-four engine was engineered with forced induction and modern fuel injection technologies, offering drivers a smooth, efficient, and powerful driving experience. Whether powering a compact sedan or a luxury coupe, the M271 engine delivers long-term dependability and refined performance suitable for everyday use and highway driving alike.
Key Features
1.6L–1.8L Inline-Four Petrol Engine – The M271 engine family includes both 1.6-liter and 1.8-liter variants, offering a flexible range of power outputs from approximately 122 hp to over 200 hp depending on configuration. This makes it suitable for both entry-level and higher-performance Mercedes-Benz models.
DOHC with Variable Valve Timing – Featuring a dual overhead camshaft (DOHC) setup along with continuously variable valve timing, the M271 delivers precise airflow management for enhanced efficiency and throttle response.
Supercharged and Turbocharged Options – Early M271 engines used a supercharger (Kompressor) for improved low-end torque, while later models transitioned to turbocharging for better fuel economy and higher efficiency under load.
Direct Injection (CGI Variants) – Some later versions, such as the M271 DE18 AL, included direct fuel injection (CGI), which improved combustion efficiency, reduced emissions, and enhanced performance.
Aluminum Alloy Construction – The use of lightweight aluminum alloy for both the engine block and cylinder head improves thermal efficiency and reduces vehicle weight, contributing to improved fuel economy.
Smooth and Quiet Operation – With refined engineering and balance shaft design, the M271 provides a smooth and quiet driving experience, typical of Mercedes-Benz standards.
