Mack Says MP13 Engine Is EPA ’27 Compliant
Chris Fisher Mack Trucks said at the ACT Expo in Las Vegas its MP13 powertrain has been re-engineered to meet stringent EPA 2027 emissions standards while also getting a performance boost for both highway and vocational applications.
The new MP13 will deliver up to 540 horsepower and 1,950 lb.-ft. of torque, but beyond raw power, the engine increases braking horsepower by more than 20%, reaching 630 braking hp for improved stopping capability.

Volvo Trucks’ Unveils Alternative-Fuel Engine
Emiliano Marzoli Volvo Trucks has unveiled a multi-billion SEK investment of an entirely new 13-liter combustion engine platform. Engineered to meet Europe’s strictest efficiency mandates, these engines are the most fuel-efficient ever produced by the OEM, delivering immediate reductions in CO2 emissions.
Crucially, the platform is built with a “fuel-agnostic” architecture; the base engine is ready to run on renewable diesel (HVO) and bio-gas, and is structurally designed to accommodate future hydrogen internal combustion engine (H2ICE) applications. This platform rollout complements Volvo’s existing battery-electric and fuel-cell programs, cementing their “three-path” strategy toward net-zero emissions by 2040 while continuing to secure top-tier safety marks, including recent five-star Euro NCAP ratings for its regional distribution trucks.

TREM V Emission Rules May Reshape Industry
Aditya Kondejkar In March, the government of India released the draft proposal for TREM V emission norms, setting in motion what could become the most significant regulatory transition for the off-highway sector since the adoption of TREM IV.
Covering construction equipment, agricultural machinery, mining vehicles, and gensets, the proposed norms represent a decisive push towards global alignment, tighter emission control, and advanced digital monitoring.
TREM V aims to sharply reduce particulate matter, nitrogen oxides, and ultrafine particle emissions by mandating technologies such as diesel particulate filters (DPF), selective catalytic reduction (SCR) systems, enhanced engine calibration, and robust onboard diagnostics. While this brings India closer to frameworks like EU Stage V, it also sets the stage for a disruptive cost cycle for OEMs and customers alike. Early estimates indicate that machine prices may rise between US$ 1,600-US$ 3,200 (₹1.5–3 lakh) depending on horsepower and engine configuration, creating immediate uncertainty around demand planning and inventory strategies.

EPA Won’t Delay 2027 NOx Rule, Plans Changes
Chris Fisher The U.S. Environmental Protection Agency is moving forward with the 2027 timeline for its heavy-duty NOx rule—currently set to take effect with the 2027 model year—but says changes are in store.
The American Trucking Associations (ATA), National Tank Truck Carriers, Truckload Carriers Association, and 49 state trucking associations in August penned a letter to EPA, asking the regulator to push implementation to 2031, citing “substantial compliance costs and operational burdens at a time when the trucking industry is already contending with historically difficult market conditions.”
Administrator Lee Zeldin in March announced that the EPA was reevaluating the Biden-era 2022 Heavy-Duty Engine and Vehicle rule that regulates oxides of nitrogen (NOx) and other emissions beginning with Model Year 2027.

Vietnam Shifts To EV Motorcycles
Akihiro Komuro Vietnam, a country known for its large number of motorcycles, is experiencing controversy over its electric vehicle policy. The policy bans gasoline-powered motorcycles in certain areas of Hanoi, the capital, and has caused a stir. Honda, which holds an 80% share of the local motorcycle market, must rethink its strategy because most of its models run on gasoline. This sudden policy change could also disrupt daily life for residents.
In July, the Vietnamese government outlined bold measures to regulate gasoline-powered motorcycles in “Prime Ministerial Directive No. 20.” Starting in July 2026, operating gasoline-powered motorcycles within the Inner Ring Road in Hanoi will be banned. The Inner Ring Road spans over seven kilometers and includes the city center, home to government offices, the Japanese embassy, and the historic Old Quarter, a popular tourist destination.

EPA Plans To Drop Phase 3 Emission Regulations
Chris Fisher In July, the Trump administration proposed a draft rule rolling back the Greenhouse Gas Phase 3 rule, among the last of – if not the biggest – looming Biden-era emissions regulations facing the trucking industry.
The proposal was announced jointly with Environmental Protection Agency Administrator (EPA) Lee Zeldin’s call to revoke the Endangerment Finding that has allowed presidential administrations to regulate greenhouse gases since 2009.
The repeal of greenhouse gas regulations is a long road that includes a lengthy rulemaking process and likely numerous legal challenges.
