Description
Kent Worthington, Powertrain Sales Development Manager with Mack Trucks, joins Beyond the Bulldog to explain Mack's approach to EPA 27 and what it means for customers. From the MP13 engine to a redesigned aftertreatment system, Kent walks through the engineering choices behind the powertrain and the goals of improving performance, fuel efficiency, durability, and uptime.
Kent also explains how changing emissions requirements affect a truck's years-long development process and the choices available to fleets. He discusses the new Keystone and Granite, the role of electrical architecture and remote software updates, and DEF-inducement updates, with a focus on helping customers understand the technology and plan for their operations.
Kent discusses:
-How evolving emissions requirements shape long-term truck development, including the powertrain strategy for the new Keystone and Granite
-How MP13 engine updates, including a 14-wave divider piston, strengthened components, and improved thermal management, are designed to support efficiency, performance, and durability
-How Mack's redesigned aftertreatment system combines serviceability with electric heating to address cold starts and low-load operation
-How DEF-inducement updates, remote software capabilities, and dealer support fit into Mack's approach to customer uptime
This episode is a practical look at the engineering and planning behind Mack's EPA 27 approach. Kent connects the technical details to the priorities that matter in daily operation: dependable performance, serviceability, and keeping trucks working over their full life.
