Sustainability meets performance.
The new Cummins X15N engine, fueled by renewable natural gas (RNG), offers the heavy-duty trucking industry an immediate solution that is both practical and sustainable.
First of Its Kind
The X15N is the first 15-liter natural gas engine to come to market, built to match the performance and reliability of its diesel counterpart.
Ultraclean
RNG reduces carbon emissions by up to 300% versus diesel. The X15N also meets both EPA and CARB regulations, with smog-forming NOx levels 90% below current EPA standards.
Powerful
With power ratings up to 500hp, torque up to 1850 lb-ft, and a 700+ mile range, the X15N is designed to suit the needs of long-haul applications.
Affordable
RNG fuel price is competitive with diesel, and the total cost of ownership is dramatically less than battery-electric and fuel cell vehicles.
Refueling Infrastructure
A robust network of natural gas fueling stations already exists nationwide. Of our 600+ Clean Energy stations, nearly 200 are tractor-trailer friendly and open to the public.
Convenient
Fueling at a fast-fill compressed natural gas (CNG) station is almost identical to diesel, both in terms of fueling speed and process.
