FOR OEMS & ENGINE MANUFACTURERS

Your priority is powertrain investment that delivers fleet performance, economics, and emissions progress.

HPDI™ is the only proven LNG/BioLNG portfolio option today that retains the diesel cycle engine, builds on the existing engine ecosystem, and creates a related development path toward hydrogen and other renewable-fuel programs.

RELEVANT TO
OEMs, Engine Manufacturers, Product Engineering
FOR FLEETS AND SHIPPERS

HPDI™ enables LNG/BioLNG with the performance, economics, and reliability fleets need.

HPDI helps fleets and shippers reduce lifecycle emissions and respond to customer and tender requirements without compromising the efficiency, uptime, and operating economics their operations depend on.

RELEVANT TO:
Fleet Owners, Fleet Operators, Shippers
FOR GAS DISTRIBUTORS AND MARKET ECOSYSTEM

Fuel adoption grows when fleets have an LNG/BioLNG engine that performs.

HPDI™ brings diesel performance to LNG/BioLNG, giving fleets a credible alternative for demanding operations. Greater fleet adoption builds vehicle demand, fuel volumes, infrastructure utilization, and growth across the market ecosystem.

RELEVANT TO:
Gas Distributors, Energy Infrastructure Investors, Regulators

Four reasons HPDI™ adoption is accelerating

Performance fleets depend on

HPDI retains the power, torque, efficiency, and durability demanding operations expect from diesel.

Built on existing architecture

Builds on existing powertrain architecture, requiring fewer fundamental engine changes than other gas alternatives.

Platform continuity

Enables LNG/BioLNG programs today while building on existing engine capability for hydrogen and other renewable-fuel development.

Proven at scale

Validated across 10,000+ trucks operating across 30+ countries with over three billion kilometers of real-world mileage.

THE OEM BUSINESS CASE

The technology works. The investment case does too.

An HPDI™ LNG/BioLNG program builds on proven diesel-engine architecture—without a ground-up truck redesign. It gives OEMs a lower-risk route to commercial return while improving certified vehicle CO2 performance where validated HPDI efficiency delivers an advantage.

Extend platform investment

Extends proven diesel-engine investments across engineering, manufacturing, service, controls, and software—reducing development scope, time, and risk.

Build future optionality

Establish a common engine-platform foundation for LNG/bioLNG, hydrogen, and other renewable-fuel programs as those markets develop.

Strengthen CO₂ position

Benefit from EU compliance flexibility through 2029 by building credits and reducing fleet emissions exposure.

Create commercial return

Add product revenue opportunities and margin from every HPDI powered truck sold.

Lower emissions shouldn't mean higher operating costs.

HPDI™ lets fleets run on bioLNG — which can cost less than diesel on an energy-equivalent basis — while dramatically cutting Scope 1 emissions. The economics are as compelling as the sustainability story.

Case study

BioLNG: the fuel source hiding in plain sight.

One overlooked resource could change two emissions problems. What if the same waste stream could cut methane at the source and fossil fuel on the road? From waste problem to transport solution.

Who HPDI™ creates value for

OEMs & Engine Manufacturers

Co-development, platform integration support, and engineering collaboration from prototype to production.

Fleet Operators & Shippers

Improve your TCO. Preserve the performance you trust while reducing fuel costs and emissions without sacrificing range, payload, or uptime. 

Market Ecosystem & Gas Distributors

Growing fuel demand and accelerating adoption require fuel suppliers, infrastructure providers, regulators and Cespira to work together as one ecosystem.
