Dan Moyer, senior analyst for commercial vehicles at FTR, emphasized that the industry’s focus is now firmly on MY 2027 engine choices and costs. He noted that the EPA’s July proposal allows for transition flexibility, such as emissions credits and nonconformance penalties (NCPs). FTR estimates that utilizing NCPs could result in a $6,000 to $7,000 fleet pass-through, which presents a notable saving compared to the estimated $8,000 to $12,000 upcharge required for a fully compliant engine.
Because truck and engine manufacturers are deploying varying emissions strategies—and some have yet to clarify their plans completely—Moyer indicated the final EPA rule could still shift the economic landscape for bulk haulers and other fleets.
“Higher NCPs would narrow the cost advantage of current-generation engines while lower NCPs would make that pathway more attractive,” Moyer said, adding that the final regulatory decisions will heavily influence 2027 engine availability, acquisition costs, and the mix of technologies fleets select.
