Volvo Rolls Out 2027 EPA-Compliant D13 Engine at ACT Expo

Key Details Volvo Trucks North America unveiled its 2027 EPA-compliant D13 engine at the Advanced Clean Transportation Expo in Las Vegas on May 4. The engine will become standard equipment on VNL and VNR Class 8 tractors, delivering up to 540 horsepower and 1,950 pound-feet of torque with 13 different power configurations available. Meeting Tough Standards The new D13 meets the EPA's strict 2027 nitrogen oxide emissions standard of 35 milligrams per horsepower-hour, down from the current 200 mg/hp-hr requirement. VTNA achieves this reduction using refined aftertreatment technology built on proven systems, resulting in more than 80% NOx emission reductions compared to current engines. Performance Gains The 2027-compliant configuration delivers an additional 4% fuel efficiency improvement over the already-enhanced VNL and VNR designs. The engine's compacted graphite iron construction provides 75% additional tensile strength, allowing engineers to increase compression ratio from 18:1 to 20:1 for maximum energy extraction. Why It Matters Volvo joins Cummins, International, and Daimler in launching EPA 2027 engines, while Paccar promises February deliveries. These compliant engines ensure fleets can meet upcoming regulatory requirements without major operational disruptions.
