Volvo has launched its next-generation D13 engine for EPA 2027 emissions requirements, meeting the nitrogen oxide limit of 35 milligrams per gallon. The new engine is designed to meet emissions standards in all 50 states and Canada.
The engine's advanced technology features a compressed graphite-iron block as its foundation, which enables significant reductions in NOx emissions while maintaining power and fuel efficiency. This marks a major achievement for Volvo Trucks North America in reducing emissions without sacrificing performance or cost.
Volvo's new D13 engine offers expanded horsepower and torque options, with ratings available from 405-hp to 540 horsepower and 1,950 lb-ft of torque. The engine also delivers up to 630 braking horsepower, providing stronger downhill control and better drivability for heavy loads and steep grades.
The enhanced engine braking performance is a significant improvement over the previous D13, saving even more fuel in various user applications and segments such as regional haul and vocational fleets. This reflects Volvo's commitment to reducing emissions while maintaining power and efficiency.
In contrast to industry concerns about sacrificing fuel economy when meeting low-NOx regulations, engine makers have actually improved efficiency while slashing NOx emissions. Volvo's new D13 engine is a prime example of this trend.
The company's goal was not only to meet emissions standards but also to maintain performance and minimize the total cost of ownership. This approach has paid off with significant improvements in fuel economy and reduced NOx emissions.
For customers already running Volvo's turbocompounding technology, there will be no difference in fuel economy. However, those switching from a VGT production engine may see a 4% improvement in fuel efficiency.
DEF consumption is expected to remain similar for long-haul customers, but fleets operating in vocational or regional haul segments may experience a slight increase in DEF use. Overall, the new D13 engine represents a major breakthrough in reducing emissions while maintaining power and efficiency.
The new D13 engine is Volvo's cleanest and most fuel-efficient Variable Geometry Turbo engine ever developed, marking a significant milestone in the company's commitment to sustainable transportation.
The new D13 engine is a significant milestone in Volvo's commitment to reducing emissions while maintaining power and fuel efficiency.
