GM and Isuzu are boosting production if the 6.6–liter Duramax diesel engine to supply increased demand and new products. Hummer has recently announced the Alpha performance line for all models and the H1 Alpha is powered by the 300hp/605 ft-lbs Duramax. GM may be looking to add the option to the H2 and H3 models (will that fit under the H3 hood?). Production of the diesel will reach 195,000 engines this year.
