Duramax Diesel Technology

15 Sep 2011

The newly developed 2.5-liter and 2.8-liter diesel engines are the newest members of the Duramax truck-engine family. They feature overhead cams, turbocharging and durable aluminum 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.

The first engines will be installed in the all-new Chevrolet Colorado pickup that will be produced in Rayong following engineering development work and retooling of the vehicle assembly line.

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 engines have been sold since 2001.
