Our new G Series truck is equipped with a Cat C18 ACERT diesel engine. We recently celebrated 85 years in the engine business, and the work we’ve put into these U.S. EPA Tier 4 Final/EU Stage IV engines is the culmination of that experience. This C18 ACERT engine has been updated to meet global emission standards. Caterpillar equips every U.S. EPA Tier 4 Final/EU Stage IV engine with industry leading electronic controls, fuel delivery, air processing and aftertreatment. The results are an engine that conserves fuel, manages emissions and facilitates greater diagnostics. For this G Series truck, engine software modifications are allowing the truck to get more work done at lower speeds and at greater fuel economy. We’ve balanced this change with the addition of 10% more torque for putting a greater percentage of the power to the ground. With our new transmission controls working in tandem with the engine, this truck is delivering significantly greater performance on grade and doing it more economically. One additional and significant change for G Series is the 772G’s ability to work at full power in higher altitudes. This truck has a 23% increase in altitude capability, allowing it to climb to just short of 3000 meters or close to 10,000 feet without affecting performance. Here are a few additional key features of the C18 ACERT: The convenience of automatic voltage charging. Key on fuel priming reducing service costs. Cold start up elevated idle for peak performance at shift start. Programmable engine idle shutdown saving fuel and reducing emissions. Delayed engine shutdown allows all systems to cool and initiate purging prior to engine shut off. The convenience of new service access points to the top of the engine. Available with an optional engine brake for long downhill grades. Fuel efficient power under all load conditions with Cat MEUI™-C fuel injectors.
