Cummins has announced that it will launch its most efficient heavy-duty diesel engine ever.
Maintaining the traditional reliability and lower operating costs that have met the needs of a diverse customer base since the X15‘s inaugural launch in 1998, the next-generation advanced X15 diesel will offer greater greenhouse gas and fuel efficiency benefits while maintaining the same ratings as the current X15 (up to 605 horsepower and 2,050 ft-lb of torque) and optimizing powertrain integration with Eaton Cummins and Cummins-Meritor.
This next-generation engine is designed to have the capability to meet future emissions regulations beyond 2027 without the need for significant changes to the architecture. This investment will help the company maintain technology leadership for the next decade while it continues to fund future research and development in hydrogen and alternative fuel engines, electric batteries, and fuel cell powertrains.
Key features.
- Improved greenhouse gas emissions and improved fuel economy.
- North American product that complies with EPA and CARB regulations.
- Power ratings up to 605hp / 2,050 lb-ft are available.
- High-power 48-volt belt-driven alternator and aftertreatment heater designed for the most stringent emissions standards.
