L9N (2018)

Overview

L9N (2018)

The 2018 L9N continues the evolution of emission leading natural gas engines from Cummins Westport, with the lowest certified Ultra Low NOx emission engines in North America – 90% lower than current North American EPA standards. With 320 hp / 1,000 lb-ft torque, and near zero emissions, the L9N is ideal for transit, refuse, and truck applications.

Cost Effective Emission Reduction
• Lowest cost Move to Zero option
- Minimal cost impact vs current natural gas product
- No infrastructure changes for current natural gas fleets
- Vehicles cost up to 70% less than electric

• Available for transit, shuttle bus, and school bus, refuse, vocational, and conventional trucks.
• Reduces smog forming NOx emissions by 90% vs. EPA NOx Standard
- One 2010 certified vehicle = the NOx emissions of TEN L9N vehicles
- Reduces Greenhouse Gas (GHG) emissions

• Capable of operating on 100% CNG, LNG, or renewable natural gas (RNG)
− Significant GHG reductions with the use of RNG

The Natural Choice
• Natural gas is the lowest carbon fuel available, with abundant domestic supply and stable pricing
• Fueling infrastructure in place and growing
