Logistics EPA's 2027 NOx Rule Adds $25,000 to Truck Costs, Sparks Pre-Buy Capacity Concerns

Regulations & Compliance EPA's Proposed Rule on Diesel Engine Derates Raises National Security Concerns
On July 9, 2026, the EPA proposed a rule that would stop new diesel engines from derating speed on emissions faults, instead giving a beep and light. The move follows EPA's admission that the current mandate causes economic hardship. The article covers the rule, related pardons, civil penalties ($45,268 per tampered vehicle), and exemptions for military vehicles.
Regulations & Compliance Proposed EPA Change Keeps NoX Limits, Alters Warranty and Deratement Rules for Trucks
The EPA released a proposed rulemaking that keeps the nitrogen oxide (NoX) emission limits from the 2023 Final Rule but makes key revisions: reducing warranty mileage from 450,000 to 100,000 miles (delayed to model year 2030), eliminating engine deratements in favor of visual/audible warnings, extending useful life provisions to 2030, and establishing noncompliance penalties. The agency says the changes retain 90% of the original NoX reductions and will not increase truck manufacturing costs.
