Westport Fuel Systems Ready for Phase 2 Emissions and Fuel Efficiency Standards

Westport Fuel Systems commended the joint efforts of the U.S. Environmental Protection Agency (EPA) and the Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) that will deliver significant environmental and economic benefits.

“The new EPA/NHTSA rules for GHG emissions and fuel efficiency from medium- and heavy-duty trucks will create a new competitive dynamic in the trucking industry,” said Jim Arthurs, Executive Vice President, Medium- & Heavy-Duty Truck Strategies of Westport Fuel Systems. “Westport Fuel Systems is well-positioned to deliver best-in-class engines and vehicles that meet increasingly stringent regulatory frameworks.”

Next generation natural gas engines and vehicles including Westport High Pressure Direct Injection 2.0 (Westport HPDI 2.0) and Enhanced Spark Ignition (Westport ESI) technologies comply with the new rule and offer significant GHG emission reduction benefits through the combination of low-carbon fuels and high-efficiency engines. In particular, Westport HPDI 2.0 has been proven to deliver diesel-like performance and fuel efficiency while providing a reduction in GHG emissions of 18 to 20 percent compared to current diesel engines.

Westport believes that the cost advantage of natural gas will increase, and Westport says, according to industry estimates, full compliance with the proposed standards will add several thousand dollars to the cost of vehicles running on conventional fuels.

“Fleet owners can focus on the environmental benefits of natural gas vehicles now and reap the economic benefits in the future,” said Arthurs.
