Eaton's Q2 Earnings Slightly Decrease Due to Higher Costs Overpowering Revenue Growth
In the dynamic world of transportation, Cummins Inc., a leading Original Equipment Manufacturer (OEM), has announced a delay in the launch of its highly anticipated 2027 X15 engine. Originally scheduled for early 2026, the new diesel engine is now set to debut in late 2026 due to significant regulatory uncertainty surrounding the Environmental Protection Agency’s (EPA) 2027 emission rules, particularly concerning greenhouse gas (GHG) and nitrogen oxide (NOx) standards for heavy-duty trucks.
This regulatory uncertainty has disrupted customer demand, causing a drop in Cummins' heavy-duty engine sales in North America by 29% year-over-year in Q2 2025. Despite the challenges, Cummins remains committed to its HELM initiative, which aims to produce high-efficiency, low-emissions engines compatible with multiple fuels, including biodiesel blends and renewable diesel. The new X15 engine promises up to 605 horsepower, 2,050 lb-ft of torque, and 4% better fuel economy compared to the 2024 model.
Cummins is also expanding its 15-liter HELM engine platform to include variants such as natural gas and hydrogen combustion engines. The company is forging ahead despite the current challenges, demonstrating resilience in the face of regulatory uncertainty.
Separately, Cummins has launched a new Fuel System designed for off-highway applications, targeting stringent emissions standards with enhanced performance and fuel economy. The system is expected to ship later in 2025.
Meanwhile, the EPA has initiated a major review and proposed the revocation of its authority to regulate greenhouse gas emissions from heavy-duty trucks, including the GHG Phase 3 standards and NOx emission limits planned for 2027. This regulatory uncertainty has caused delays in engine product rollouts and hesitant market pre-buys, as stakeholders await clarity or changes from the EPA.
In other news, Daimler Trucks North America (DTNA) has expressed support for the EPA's GHG3 rollback, while other OEMs have shown caution. The California Air Resources Board (CARB) is closely monitoring these developments, as are industry bodies like the Technology & Maintenance Council (TMC).
On a separate note, motor fuel taxes have seen fluctuations in various states. Ten states have seen an increase, while three have seen a decrease. For the latest updates and trends in the transportation industry, consider subscribing to Transport Topics' newsletter.

The regulatory uncertainty in the transportation industry, particularly regarding the EPA's 2027 emission rules, has not only affected Cummins' business, causing a drop in heavy-duty engine sales, but also the finance sector, as it has caused delays in engine product rollouts and hesitant market pre-buys. To address these concerns, Cummins is forging ahead with their HELM initiative, aiming to produce high-efficiency, low-emissions engines that are compatible with various fuels, including those in the finance sector such as biodiesel blends and renewable diesel.
Cummins is also diversifying its 15-liter engine platform to include variants powered by natural gas and hydrogen, demonstrating their commitment to both the business of heavy-duty truck production and the finance sector's push for cleaner, alternative fuels.
