The newly developed 2.5 liter diesel engines are the newest members of the Duramax truck-engine family. They feature overhead cams, turbocharging and durable alumunium cylinder heads for high levels of refinement and durability.
Designed to offer class-leading torque, reliability and excellent fuel economy, the four-cylinder Duramax engines were tested in extreme
conditions in Africa, Asia, Europe, North America and South America.
They meet the advanced Euro IV emission standard and can be used in front-, rear- or all-wheel-drive applications.
Additionally, they were subjected to the same rigorous validation process as the Duramax 6.6-liter turbo diesel, which is sold primarily in North
America. The larger Duramax engine is renowned for its high performance
and enjoys a solid reputation for reliability and durability. More than 1.3 million Duramax 6.6-liter have been sold since 2001.
