Where to Buy

Natural gas is among the green technology options that truck and bus manufacturers now offer. Natural gas vehicles are well-suited to high-fuel-use fleets that operate in return-to-base mode or in regional corridors. Fuel cost savings can reduce fleet operating expenses.

Contact your truck or bus dealer to learn about the natural gas vehicles they offer. Dealers can help with working out the payback period, onboard fuel needs, tank location, and specifications for a natural gas vehicle. Dealers can also help identify truck body manufacturers that supply compressed natural gas (CNG) and liquefied natural gas (LNG) fuel systems. The vehicle manufacturers listed below offer factory-built natural gas vehicles:


Warranty coverage for natural gas trucks is similar to the coverage offered on diesel trucks. For its 8.9 litre ISL G and 11.9 litre ISX G engines, Cummins Westport offers warranties that cover engine failures caused by defects in material or factory workmanship. These warranties apply for two years or 250,000 miles (402,336 kilometres), whichever comes first. Similar coverage is provided on engines used in transit and school bus applications.
