Volvo's Redesigned D13 Engine Meets 2027 EPA Standards with Major Power Boost

Key Details Volvo Trucks North America unveiled a completely redesigned D13 engine engineered to meet the EPA's 2027 emissions standards. The new powerplant cuts nitrogen oxide emissions by 83% and particulate matter by 50%, making it Volvo's cleanest engine to date while maintaining the fuel efficiency and reliability fleets depend on. Performance Gains The 2027 D13 delivers up to 540 horsepower and 1,950 lb.-ft. of torque, with engine braking performance reaching 630 braking horsepower, up from 500 in previous models. These improvements support heavy-haul operations, B-train configurations in Canada, and demanding vocational applications without sacrificing driver experience. Technical Innovation Volvo achieved these gains through fundamental engine redesign, including a switch to compacted graphite iron block construction that increases tensile strength by 75%. The compression ratio jumped from 18:1 to 20:1, while a new 14-wave piston design with precision fuel injection reduces soot and regeneration cycles. Why It Matters The refined transmission keeps engines operating at peak efficiency longer, delivering smoother shifts and enhanced acceleration. Volvo states its production, supply chain, and dealer network are aligned for day-one 2027 compliance, ensuring drivers and fleet operators can transition smoothly to cleaner technology without operational disruption.
