In 1998, a partnership was formed between General Motors and Isuzu to begin the in-house manufacture of diesel engines. Shortly after, DMAX Ltd. created the first generation of Duramax engines, including the LB7 Duramax diesel engine, which featured 300 HP and 520 lb-ft of torque. Engines produced by DMAX Ltd. were designed to be high-performance and advanced, such as their 6.6L V8 turbodiesel engine, with 32 valves on a cast-iron block, direct fuel injection, under-mounted injectors and a passive catalytic converter. By 2012, General Motors and Isuzu had produced 1.5 million Duramax engines, and their legacy continues to grow. DMAX Ltd. currently maintains a 500 employee, 584,000 square-foot facility in Moraine, Ohio.
6.6L DURAMAX L5P
Newly introduced for 2017, the Duramax L5P is currently the most versatile and powerful product on the line. The Duramax L5P produces 445 HP and 910 lb-ft of torque, in addition to exceeding modern emissions and environmental standards. This engine replaces the 6.6L Duramax LML in the Chevrolet Silverado and the GMG Sierra. It's electronically controlled and has a variable geometry turbocharger.
6.6L DURAMAX LML
Introduced in 2011, the 6.6L Duramax LML includes advanced emissions equipment, which is able to significantly reduce nitrogen oxide emission levels. This engine was used from 2011 to 2016 but was eventually replaced by the Duramax L5P in 2017. Nevertheless, the engine was very powerful and not only met but exceeded environmental standards. It can operate at peak horsepower of 397 HP and peak torque of 765 lb-ft, making it an impressively strong addition to the Duramax line. It was the first Duramax to require the use of diesel exhaust fluid.
2.8L DURAMAX LWN
The 2.8L 4-cylinder Duramax LWN is rated by the EPA at 30 MPG for the 2017 model year. This diesel engine was added to the 2016 GMC Canyon and the Chevrolet Colorado, competing against the Frontier and Tacoma pickups of Nissan and Toyota. This engine has 181 HP and can haul up to 369 lb-ft of torque. The 2.8L Duramax is a variable geometry, turbocharged diesel engine, with dual overhead camshafts and a high-pressure common rail injection. Both the GMC Canyon and the Chevrolet Colorado can tow 7,500 pounds or more with the properly installed equipment.
6.6L DURAMAX LGH
The 6.6L V8 Duramax LGH is designed for commercial trucks and fans, and consequently has two builds designed specifically for each. First produced in 2011, the 6.6L Duramax LGH provides performance to cab and van fleet vehicles and is available on both the Chevrolet Express and the GMC Savana. This engine has two options for horsepower and torque: 335 HP and 685 lb-ft of torque or 260 HP and 525 lb-ft of torque. Both include a turbocharger engine and cooler. The LGH was designed to compete regarding performance with other commercial vehicles. As an engine designed for "incomplete vehicles," the 6.6L Duramax LGH has separate federal emissions standards.
Duramax engines are high-performance diesel engines that both meet environmental standards and offer performance to spare. A diesel engine is a great option for both commercial cars and used trucks.
