In this edition of ACT News Talks Tech, Patrick Couch, Senior Vice President of Technical Services with TRC’s Clean Transportation Solutions team, sits down with Steve Collins, Director of Field Sales Engineering at Daimler Truck North America, to discuss the next generation of clean diesel engines and what the EPA’s 2027 regulations mean for fleets today.
As the 2027 standards approach, fleets are evaluating how upcoming engine platforms will impact operations, maintenance, and long-term costs. While the regulations are still more than a year away, the technologies and design changes required to meet them are already shaping purchasing decisions.
During the conversation, Collins explains how Daimler Truck North America’s Gen 6 engines were designed to meet evolving emissions requirements, and where fleets may notice differences in day-to-day performance, service intervals, and overall uptime.
Couch and Collins also discuss how warranty and useful life requirements factor into total cost of ownership, and what fleets should be asking OEMs now as they prepare for the transition.
The discussion offers an early look at how clean diesel technology is evolving and what it means for fleets navigating near-term procurement decisions.
Watch the full interview to hear Collins’ insights on how EPA 2027 is influencing engine design and what fleets should consider as they evaluate their next equipment investments.
