Fuel Economy & Range: 

Fuel Economy & Range LNG better suited to longer range routes than CNG LNG tank systems offer 500+ mile range Diesel like efficiency – in use.

Example Fuel Savings For LNG Fleet: 

Example Fuel Savings For LNG Fleet Diesel equivalent fuel efficiency translates into real savings with LNG 20 trucks 5 mpg 80,000 mile/yr/tuck

Petroleum Use Reduction: 

Petroleum Use Reduction High diesel displacement with HPDI LNG trucks. LNG trucks are a very effective approach for petroleum use reduction.

LNG Truck Benefits: 

LNG Truck Benefits LNG – one solution for a clean trucking future

LNG Trucks – An Alternative Today: 

LNG Trucks – An Alternative Today Oil prices continue to rise dramatically. LNG reduces air pollutants and greenhouse gases. LNG - an attractive economics for heavy duty trucks. Funding available for fuel and equipment. Proven in heavy duty service. Available today.
