Westport Fuel Systems Inc. ("Westport") (TSX:WPRT Nasdaq: WPRT), today announced Cespira, its joint venture with Volvo Group, released new technical details of HPDI™ 3.0, the next generation of its proven High Pressure Direct Injection fuel system.
HPDI 3.0 retains proven HPDI combustion principles while advancing fuel rail-pressure control, hardware durability and system integration. The new fuel system supports liquefied natural gas (LNG) and renewable bio-based liquefied natural gas (bioLNG) today while preserving adaptability for future low- and zero-carbon fuels.
Performance Enhancements
At its core, HPDI 3.0 incorporates a new fuel rail-pressure control architecture that improves fuel economy and engine performance while simplifying OEM calibration. Higher injection pressure capability unlocks greater power and efficiency from the latest high-performance compression-ignition engines, while the architecture is designed to support compliance with future global emissions regulations.
Improved Durability and Greater Integration Flexibility
The new hardware integrates proven HPDI injector dynamic sealing technology to enhance component service life. A modular fuel rail-pressure control architecture gives OEMs greater packaging flexibility across different engine layouts. The new system supports larger engines, including V12 and other multi-bank configurations, by allowing fuel pressure control across separate cylinder banks. This broadens the potential application of HPDI 3.0 across demanding on-road and off-road sectors.
Built for Natural Gas and Biogas Today, Adaptable for Future Fuels
HPDI 3.0 reinforces the near-term value of natural gas and renewable natural gas for heavy-duty transport by enabling the use of LNG and bioLNG with diesel-like performance, improved efficiency and attractive total cost of ownership. The architecture also maintains a clear pathway for future fuel-specific applications, including hydrogen, as those markets develop.
"Cespira's revenue increased 125% year over year from Q2 2025 to Q2 2026, underscoring strong market validation for HPDI technology. With continued gains in efficiency, attractive total cost of ownership and improved fuel price stability, we believe HPDI is well positioned to grow adoption momentum with OEMs and fleets," said Dan Sceli, Chief Executive Officer of Westport.
"HPDI 3.0 strengthens both the immediate and long-term business case for OEMs. More precise fuel rail pressure control, higher injection pressure capability, enhanced durability and improved fuel economy make HPDI 3.0 a more compelling proposition for LNG and BioLNG applications. The architecture is also more readily adaptable to future fuel-specific systems for hydrogen and low-carbon fuels, giving OEMs greater flexibility to build on their HPDI investment and expand their product portfolios as those fuel markets develop," said Scott Baker, CTO of Cespira.
HPDI 3.0 builds on a proven technology foundation, with the current generation accumulating more than 3 billion kilometers of real-world operation across 12,000+ trucks in over 35 countries. Cespira will begin production of HPDI 3.0 in the fourth quarter of 2026, with the first HPDI 3.0 equipped vehicles expected on the road in early 2027.
