New Duramax engines to propel Chevrolets challenge into the 2-ton pickup truck market

Chevrolet takes diesel engine building to new heights as it introduces the new Duramax engine. The Duramax engine is a product of more than a century of heritage, evolution and innovation of automotive engineering.The engine is built tough as it is made of premium grade materials that are geared to promote durability and optimum performance. Graphite coated cast-aluminum pistons reduce friction and power losses. The four-cylinder engine is built to endure the harshest of driving conditions, and is tested in the extreme environments of Africa, Asia, Europe, North and South America. The engines are equipped with a high-pressure common rail fuel injection system and pneumatic & position feedback controlled turbocharger; with the 2.8L variant sporting a variable geometry feature.

The end result: engines that are among the industry’s most powerful and fuel-efficient diesel offerings in their respective displacement classes. With an advanced Body Control Module (BCM) and Engine Control Unit (ECU), the Duramax engine provides quick engine response and accurate fuel injection leading to better fuel efficiency. The Duramax engine also has a balancer shaft that reduces engine vibration and harshness providing better driving comfort for its driver and passengers.

The new Duramax diesel engine is available in 2.5 and 2.8 liter displacements. The 2.8L automatic variant is capable of producing 180hp @ 3800rpm of power, 470Nm @ 2000rpm of torque.


To show General Motors’ commitment in making sure that the manufacturing of the Duramax would be nothing short of top standard, GM built a $200 million, 54,275-sq.m assembly plant in Rayong, Thailand. It is equipped with the latest engineering technologies including precision lasers and computer guided gauge sequences to produce up to 120,000 engines in a year. The powertrain underwent 9 months of intensive validation to guarantee an impeccably efficient workflow.

Apart from the high-tech facility, GM also invested heavily on the technical proficiency of its employees. Key personnel went through extensive technical training in Japan, Korea and Germany to make sure that the Duramax engines are handled only by highly skilled and knowledgeable professionals.

The new Colorado and the upcoming Colorado-based ASEAN developed Trailblazer will come with the new Duramax engines. The Colorado will be Chevrolet’s first offering in the pick-up segment since The Covenant Car Company (TCCCI) took over management of the brand in the Philippines. The Colorado will sport both 2.5L and 2.8L variants of the Duramax engine, and will be available in both 4x2 and 4x4 drivetrains with Automatic and Manual transmission options.
