Natural gas prices continue to track below those of diesel fuel. The average price for natural gas is up to 25% less per gallon than diesel*. The Westport LNG system enables fleet operators to take full advantage of this price differential and deliver significant fuel cost savings. Additional cost savings depend largely on the extent of offset funding obtained and the fuel savings achieved for each customer. Fuel savings increase with higher fuel consumption applications (high annual mileage, heavy loading, etc.) and obviously with higher fuel price differentials to diesel.

The economics of LNG trucks are expected to improve over time. The incremental LNG System cost will be reduced with: increasing sales volumes; and, the increasing cost for diesel engines with aftertreatment devices—a necessity for diesels to meet emissions regulations. In addition, fuel pricing is expected to decline as volumes grow for vehicular use.

Westport's Sales Representatives can work with potential customers to perform a Life-Cycle Cost (LCC) analysis, based on the particular metrics of their fleet. This will clearly lay out the economic potential of using Westport-quipped LNG trucks in their fleet.

The 2006 Westport LNG System has U.S. EPA and CARB certification. Please consult your insurance broker for quotes.

Yes, the Westport LNG System is compatible with Jake Brakes.

At this time, the Westport LNG System is only compatible with manual transmissions.

Westport's driver training program is approximately three hours in duration. LNG refueling procedures are station specific, and this training must be offered in conjunction with station owner / operator. Westport can collaborate with station owner / operator on training if requested to do so.

For driver safety procedures please refer to the LNG Fuel System Operating Guide, supplied with your vehicle.

Natural gas prices continue to track below those of diesel fuel. The average price for natural gas is up to 25% less per gallon than diesel*. The Westport LNG System enables fleet operators to take full advantage of this price differential and deliver significant fuel cost savings. An LNG operator can realize a total tax advantage of over USD$1.00 per diesel equivalent gallon.

Pricing of LNG depends on a number of factors including location, quantity of fuel, and purchase options (fixed price, indexed price, spot price, etc.). The U.S. Energy Bill provides a USD$0.69/diesel-equivalent gallon federal tax differential for LNG fuel over diesel. The California state taxes on fuel provides a USD$0.23/DEG tax advantage for LNG, and also offers an "annual fee" decal option which reduces LNG tax further for higher fuel users. Current information indicates the typical tax savings for a truck operating 100,000 miles/yr at 6 mpg would be USD$0.32/DEG with the decal purchase.

In general, LNG is available at attractive prices on an energy-equivalent basis to diesel fuel and supports an economic incentive to offset the initial incremental capital cost of an LNG System. Clean Energy Fuels is one of several fuel providers that can provide pricing of LNG to fleets.

Natural gas fueling infrastructure is the fastest growing amongst alternative fuels for transportation in North America. Clean Energy Fuels Inc., North America's largest provider of vehicular natural gas, is one of several fuel providers.

Natural gas is one of the world's most abundant sources of primary energy, and has been in use as a transportation fuel for more than 60 years. Today, with over 4.5 million vehicles operating worldwide on natural gas, it is among the safest of transportation fuels.

All LNG System trucks are equipped with Amerex gas detection system. A display panel is located in the cab of the truck and indicates two levels of leaks: "Trace Leak" when measured gas concentration is greater than 20% of the lower explosive limit, and "Significant Leak" when measured gas concentration is greater than 50% of lower explosive limit. An audible alarm also sounds for "Significant Leak". The display also indicates if a sensor circuit is not working properly. Each truck has two sensors: one in the engine bay and one in the cab. The system display will also alert the driver as to which zone the leak was located.

For driver safety procedures please refer to the LNG System Operating Guide, included with your vehicle.

Westport has partnered with Cummins repair shops and other qualified repair shops, to establish an LNG System service network in the L.A. basin area. Service partnerships in other regions will be established as customer demand dictates.

Westport's team of service experts are the central point of contact for organizing repairs and maintenance on Westport LNG Systems. In Los Angeles, all initial LNG System warranty repairs will be completed utilizing authorized Cummins repair shops. Customers are encouraged to contact Westport Service for more details on support in their area.

Westport provides training to customer repair technicians for certain regularly scheduled maintenance repairs, and provides local part stocking for LNG System components. Customers have the option of purchasing maintenance items to stock at their own facility, after having received training for basic maintenance procedures.

Maintenance of the LNG System coincides with regularly scheduled vehicle and engine maintenance intervals. Please see the LNG System Maintenance Schedule on the Service and Support page for more details.

The U.S. Highways Bill offers tax credits on an LNG System vehicle purchases. Other state or regional government agencies and natural gas companies may offer additional incentives for the specific regional application. For example, the Port of Los Angeles is considering an incentive program to encourage early adoption of clean LNG vehicles in the port.
