Volvo Trucks North America is preparing fleets for the next regulatory cycle with the launch of its most fuel‑efficient and lowest‑emitting engine to date, the next-gen D13.
The new D13 platform is designed to comply with the U.S. Environmental Protection Agency’s 2027 emissions standards, cutting nitrogen oxide output by more than 80 percent compared with today’s requirements while preserving the drivability and uptime expectations of heavy‑duty customers.
The engine builds on more than a decade of development from Volvo’s existing D13 architecture, the company’s most widely produced engine globally.
According to Volvo, the updated design meets emissions requirements in all 50 states and supports fleets operating in long‑haul, regional haul, and vocational segments without the need for market‑specific configurations.
Peter Voorhoeve, President of Volvo Trucks North America, said the new platform reflects the company’s focus on delivering lower emissions and stronger performance without disrupting fleet operations.
“This engine is our most powerful, fuel‑efficient engine ever and delivers on every front for our customers: lower emissions, strong performance, and compatibility with the fuels and systems fleets already use,” he said.
More Power & Braking Capability
The next‑generation D13 offers expanded horsepower and torque options, with ratings reaching 540 horsepower and 1,950 lb.-ft. of torque.
Volvo has also increased engine‑braking capability to 630 braking horsepower, giving operators improved downhill control and responsiveness in steep or heavy‑load environments.
Fuel Efficiency Across Applications
Fuel economy was a central design priority.
Volvo said refinements to the platform support improved efficiency for regional and vocational operations while maintaining strong performance for long‑haul duty cycles.
The engine is compatible with renewable diesel (R100) and biodiesel blends up to B20, giving fleets flexibility as alternative fuels become more available.
Built On Proven Emissions Technology
Rather than introducing an entirely new after-treatment system, Volvo retained and advanced the technology already used across its current D13 lineup.
The approach is intended to support durability, serviceability, and uptime as fleets transition to the 2027 standards.
The engine is engineered to meet the EPA’s 35‑milligram NOx limit and maintain compliance nationwide.
Ready For 2027
Volvo developed the engine in parallel with its production operations, dealer network, and service infrastructure to ensure parts availability, technician training, and support readiness when the new standards take effect on January 1, 2027.
The engine will be offered across all Volvo truck models.
