Upgraded Chevrolet engine among highest in class with its power and torque

Chevrolet Thailand introduced upgraded Duramax engines for 2014 yesterday. The new 4-cylinder turbo-diesel engines produce one of the highest power and torque outputs in its class while exceeding industry-standard emissions ratings. Among the Chevrolet vehicles that will be powered by the new engines are the Colorado and Trailblazer that are sold in the Southeast Asian markets.

Upgraded components such as the water-cooled variable geometry turbocharger, high-pressure common-rail fuel delivery system, exhaust gas recirculation (EGR) system, intake manifold, cylinder head, cylinder block, balancer shaft unit, and engine control module have contributed to the power and efficiency increase of the Duramax engines.

The 2.8-liter Duramax can produce 200 PS and 500 Nm while the 2.5-liter variant is capable of 163 PS. These engines will be paired with a re-tuned 6-speed transmission to optimize the output while being efficient. The upgrade allows the Duramax to comply with the Euro-4 standard, and can be further upgraded to meet Euro-5, Euro-6, and US emission standards if deemed necessary.

The upgraded engines will be built in the General Motors Powertrain facility in Rayong, Thailand. Aside from the providing power to the Colorado and Trailblazer, the engine will also be exported to other global markets. The GM plant that will produce the engine is one of the company’s most advanced diesel engine facilities, and the first to produce the Duramax engines. In 2012, the facility introduced a new engine block line that offers strict in-house quality control and a more efficient production.
