Westport's Next-Gen CNG System Debuts at ACT Expo 2026

Key Details Westport is bringing its advanced compressed natural gas fuel system to ACT Expo 2026 in Las Vegas this May. The demonstration marks the first North American showcase of technology designed to deliver diesel-level performance using widely available CNG fuel. Why It Matters The high-pressure direct injection (HPDI) system will power a Volvo VNL 300 producing 500 horsepower and 1,850 pound-feet of torque with fuel efficiency comparable to diesel models. This represents a major step toward commercializing the technology for North American fleets seeking cleaner alternatives without sacrificing performance. How It Works Unlike new engine designs, this system modifies existing diesel engines to run on natural gas. No spark plugs, transmission changes, or cooling system modifications are required, and maintenance schedules remain identical to standard diesel trucks. When serviced, diesel mechanics can work on it using existing equipment. Market Advantage Westport engineered the high-pressure CNG platform specifically for North America's infrastructure, which relies on pipelines rather than LNG. The technology through Cespira - a Westport-Volvo joint venture - already powers over 10,000 trucks across 30+ countries using liquefied natural gas, proving its commercial viability and reliability.
