3.0L I-6 LM2 Duramax^® Turbo-Diesel

Diesel engines are all about torque, and when taking off under load, the LM2 delivers it at low rpm, where it counts. The engine’s peak torque of 460 lb.-ft. (624 Nm) is achieved at only 1,500 rpm, with 85 percent of that max twisting force available by 1,250 rpm. This gives drivers an immediate feeling of pulling power as soon as they touch the gas pedal. Noise-attenuating elements like acoustic resonators and fully decoupled cam covers with rubber-isolated fasteners help curb sound levels for exceptional refinement.
