International considers staggered rollout of EPA 2027-compliant engines amid regulatory uncertainty

International Motors, a subsidiary of Traton Group, is weighing a phased introduction of model-year 2027 engines to comply with pending nitrogen-oxide emissions regulations, according to Christian Levin, CEO of Traton. The move comes as the draft EPA 2027 rulemaking, unveiled July 9, 2026, leaves critical details unresolved, leaving OEMs scrambling to finalize compliance strategies. Levin emphasized International’s flexibility, noting the company could continue producing current engines if financially viable, while also highlighting the uncertainty surrounding the rule’s final implementation. “We can, of course, also choose to continue with the current platform if that is financially more viable,” Levin said during an analyst call following the release of Traton’s Q2 2026 earnings. “Still, exciting times in the U.S. to see where this finally ends up.” International had already debuted EPA 2027-compliant engines in January 2026, including its S13 integrated powertrain, which was launched in August 2022 and designed from the ground up for the new regulations. However, the lack of clarity in the draft rulemaking has left fleets in the dark about potential cost impacts. Dan Kayser, International’s executive vice president of commercial operations, acknowledged the uncertainty in a January media roundtable, stating, “We are marching forward as though this emissions regulation lands at the beginning of 2027.” The regulatory uncertainty hasn’t dampened International’s order momentum. Truck orders surged 209% year-over-year in Q2 2026 to 22,924 vehicles, up from 7,416 in the same period last year, and rose 22% compared to Q1 2026’s 18,859 orders. Despite the order boom, sales dipped 10% to 13,130 vehicles in Q2, though they were up 26% from the first quarter’s 10,413 units. The company posted its first quarterly profit in a year, with a $151.29 million operating profit in Q2, nearly triple the $53.46 million recorded in Q2 2025. A significant contributor to the profit rebound was $136.5 million in Section 232 tariff refunds and recoveries for U.S. content under the International Emergency Economic Powers Act tariffs. Traton, which reports earnings in euros, also revised its North American Class 8 sales forecast upward, now expecting between 259,000 and 284,000 trucks for 2026, compared to 259,000 units sold in 2025. The adjustment reflects “improving U.S. fleet economics, strong freight rates, and some EPA ’27 pre-buy activity,” Levin noted. While confidence in the freight market grows, Levin cautioned that geopolitical uncertainty and tariffs remain unresolved risks. The broader industry is also grappling with the EPA 2027 rulemaking, with Volvo Group CEO Martin Lundstedt warning on July 17 that the rulemaking had “fogged up” the outlook for truck sales in the second half of 2026. Cummins, meanwhile, announced plans to phase in its X15 and X10 engines compliant with the new emissions standards, adding to the industry-wide scramble for compliance solutions.
