GM Duramax 6.6L Diesel Engine
The original Duramax was a vast improvement over GM’s previous indirect-injection diesel. And it beat both Dodge and Ford to the punch when it debuted for the ’01 model year. Two more years would pass before Cummins-equipped trucks were upgraded to common-rail injection. However it was another few months after that before Ford joined the higher-pressure party with its HEUI 6.0L Power Stroke engine. It wasn’t until the ’08 model year that Ford came to market with a true high-pressure common-rail—in the form of the 6.4L Power Stroke.
Until the introduction of the Duramax, GM relied on the all-iron, IDI 6.5L GM V-8. Which produced a decent 215 hp and 440 lb-ft of torque in its most powerful configuration. The new, aluminum-headed 6.6L Duramax V-8 hit the market with a very impressive 300 hp and 520 lb-ft of torque in its first configuration. And it has only gotten stronger with age. While still meeting increasingly strict emissions requirements.
