What is a remanufactured car engine?October 21, 2026
What is engine assembly?The M276 is a new generation of V6 gasoline engines introduced by Mercedes-Benz in 2010 to fully replace the older M272 engine series, which featured port injection.
Features and technical evolution of the specific variant M276.950:
60-degree cylinder angle design: Unlike the M272’s 90-degree cylinder angle, the M276 employs a 60-degree V6 layout, achieving exceptional balance and extremely low vibration without the need for additional balance shafts.
Naturally Aspirated + Third-Generation Direct Injection (BlueDIRECT): The M276.950 is the most iconic 3.5-liter (3.5L V6) naturally aspirated variant in the M276 family. It is equipped with third-generation Piezo Direct Injection, Multi-Spark Ignition, and on-demand oil and water pumps, delivering a 24% improvement in fuel economy compared to the M272 while significantly increasing horsepower.
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.
