Featured Diesel of the Month: Duramax

Featured Diesel of the Month: Duramax

If you love GM trucks and you're looking for a diesel, then our featured diesel of the month is the one for you! The Duramax family of diesel trucks is rough, tough and ready to work, offering the significant torque, horsepower and excitement that you expect from a GM diesel truck. Learn more about this tough breed of truck through a short history of the partnership that started it all in 1998 through today -- with over 1.5 million Duramax diesel engines sold by 2012.

The Early Years

In 1998, General Motors and Isuzu teamed up to establish an engine manufacturer which they dubbed DMAX Ltd. with the goal of producing a brand-new diesel engine that was expected to take the U.S. market by storm. The high-pressure direct-injection powerplant was initially produced in Moraine, Ohio with the first few engines rolling off the production floor in mid-2000. The First Generation Duramax engine, the LB7, debuted in 2001 with 300 HP and 520 lb-ft of torque in three-quarter and one-ton trucks. This beast had some kick: a 6.6L V8 turbodiesel engine with aluminum heads, fixed-geometry turbo, a passive catalytic converter and injectors mounted under the valve covers. By 2012, General Motors was able to announce that more than 1.5 million Duramax engines had been produced since the beginning of the partnership with Isuzu. Today, more than 500 employees continue the tradition in a 584,000 square foot facility -- still in Moraine, Ohio. 

Duramax engines have undergone changes over the years, while still maintaining the high quality and brand identity that you've come to expect from DMAX Ltd. engines.

Engine Options

Duramax engines have undergone changes over the years, while still maintaining the high quality and brand identity that you've come to expect from DMAX Ltd. engines. Currently, the available engine options include:

  • 6.6L DURAMAX L5P: First introduced for the 2017 model year, the 6.6L Duramax L5P produces a staggering 910 lb-ft of torque and 445 horsepower -- more than any previous generation. The variable geometry turbocharger is electronically controlled and also includes a functional hood scoop. 
  • 6.6L DURAMAX LML: One of the most fuel-efficient and powerful of the Duramax line. This particular model was produced from 2011-2016 and required the use of diesel exhaust fluid as part of the complex system of emission-reducing equipment. 
  • 2.8L DURAMAX LWN: General Motors added the more moderate 2.8L LWN Duramax to their lineup in the 2016 model year to support the Chevrolet Colorado and GMC Canyon line of mid-size trucks. 
  • 6.6L DURAMAX LGH: Still in production today, the LGH version is generally used for commercial vehicles such as Express/Savana vans and Sierra/Silverado HD chassis cabs. Essentially a detuned LML, the LGH is produced in two different power configurations. 

When you're looking for a serious performance vehicle, GM trucks with a Duramax engine are nearly impossible to beat.
