What is a remanufactured car engine?October 21, 2026
What is engine assembly?The M272 is a classic family of naturally aspirated V6 gasoline engines widely used by Mercedes-Benz from 2004 to 2013 to replace the previous-generation M112 series.
Evolution and Technical Features of the Specific Code M272.974 (Exclusively for 4MATIC All-Wheel Drive):
Adaptation for 4MATIC All-Wheel Drive Chassis: The M272.974 is the 3.5-liter (3.5L V6) variant within the M272 family designed exclusively for 4MATIC all-wheel drive. Unlike the rear-wheel-drive versions (such as the M272.964), the M272.974 features a specially designed oil pan with a through-hole channel for the front right drive shaft to pass through, enabling compatibility with the front differential and the 4MATIC all-wheel-drive chassis architecture.
Core technologies remain unchanged: a 90-degree angle aluminum cylinder block, Silitec aluminum-silicon alloy cylinder liners, Dual Continuous VVT (variable valve timing), a two-stage magnesium alloy variable intake manifold, and a balance shaft. Power delivery is exceptionally smooth, and this engine is primarily found in all-wheel-drive luxury models such as the Mercedes-Benz E 350 4MATIC (W212/late-model W211), S 350 4MATIC (W221), and C 350 4MATIC (W204).
Our products are exported to various parts of the country, and the customers we have worked with have received unanimous praise. The company has invested over 20 million yuan in high-end remanufacturing equipment imported from abroad and a first-class production team in the country. Our warehouse has a total area of over 8000 square meters, with scientific management and sufficient supply of goods.
