Delivers pressurized fuel directly to the intake ports ahead of the valves.
The Mercedes-Benz M272 engine is a staple of the brand's "modern classic" era. Produced from 2004 to 2011, this 60-degree V6 powerplant succeeded the M112 V6 and found a home in a vast array of models, including the W203 C-Class, W211 E-Class, W164 M-Class, R171 SLK, and the Vito van. While beloved for its smooth power delivery and responsive nature, the M272 is also known for specific mechanical vulnerabilities—namely balance shaft wear and intake manifold issues.
