Mack Trucks announced two new variants of its Mack MP13 engine designed to meet the stringent California Air Resources Board (CARB) 2024 Omnibus emissions standards, as well as a battery-electric version of the Pioneer.
The new engine options, rated at 425 hp with 1,750 lb.-ft. of torque and 455 hp with 1,850 lb.-ft. of torque, are engineered to achieve a 75% reduction in nitrogen oxide (NOx) and a 50% reduction in particulate matter (PM) emissions over current U.S. EPA standards. The announcement underscores Mack’s ongoing commitment to cleaner diesel technology as the industry transitions toward low-emission and zero-emission solutions.
Jonathan Randall, president of Mack Trucks North America, emphasized the importance of providing fleet customers with sustainable yet dependable options.
“Mack will have a 13-liter engine that will be CARB 2024 Omnibus-compliant once certified, allowing Mack customers in California to have a fuel-efficient and more sustainable diesel engine to meet all of their highway application needs,” said Randall. “At the same time that Mack is working to ensure its diesel customers have a durable, reliable highway truck, we also continue to invest and investigate other sustainable solutions, such as battery electric and hydrogen fuel cell power.”
The MP13 variants will power the newly launched Mack Pioneer, the company’s next-generation Class 8 on-highway truck. These engines feature a 48-volt alternator to support a heated exhaust aftertreatment system, a new 10kW heater, and a supplementary battery box to meet low-NOx startup requirements. Specialized engine software further ensures compliance with CARB’s emissions limits.
In parallel with its clean diesel developments, Mack also unveiled the all-electric version of the Pioneer. The battery-electric Mack Pioneer EV is purpose-built for regional haul and vocational applications, featuring a modular battery system, regenerative braking, and fast-charging capabilities. This electric variant represents Mack’s continued investment in sustainable transport options.
