The “Alpha” was a comprehensive redesigned H1 equipped with GM Duraxx diesel and 5-speed Allison transmissions. The previous version of the H1 with the 6.5L “Optimizer” turbo diesel engine experience from bad sales; A lack of energy was one of the reasons for customer resistance.
The Duramax engine was equipped with cooled exhaust gas circulation and an internal engine oil cooler, reducing engine fuel by 40%. Since the distance between the air ducts that protrude from the hood is limited, the fan system has been changed by placing it directly under the cooling deck and driving it directly from the crankshaft pulley through a special gearbox. Several other modifications to the cooling system were needed to support the cold start of -34°C (-30°F).
Other important changes include the use of special high-strength steel in the chassis, a stronger steering wheel; Styler Asbestos, redesigned accelerated hubs to use quiet helicopter transmissions, new induction, exhaust and electric power systems; and redesign of the fuel supply and filter system. The Duramax engine has more torque at lower engine speeds than the 6.5-liter engine. In combination with a lower gear ratio, the 2018 Hummer H1 became stronger, other changes include the central tire filling and a new interior.
