Hyliion, Cummins Approved for Hypertruck ERX Powertrain

Cummins Inc. and Hyliion Holdings Corp. have successfully obtained the dual executive order from the California Air Resources Board (CARB) for the Hypertruck ERX powertrain paired with the Cummins ISX12N engine.

“This certification is pivotal to commercializing our Hypertruck ERX powertrain and enables us to provide our customers with a solution that supports their sustainability goals.” said Thomas Healy, founder and CEO of Hyliion, a provider of electrified solutions for Class 8 semi-trucks. “More than just an environmental certification, this achievement represents the commitment to innovation, sustainability, and industry leadership we share with Cummins.”

The companies have worked together to meet emissions standards and secure key environmental certifications to sell the powertrain in California. The Hypertruck ERX is an electric range-extender powertrain that uses the Cummins’ natural gas engine as an onboard generator to recharge the batteries.

Offering up to 75 miles of electric range, the Hypertruck ERX powertrain meets California emissions standards to qualify as a NZEV under CARB’s ACT and ACF rulings. When utilizing the generator, the Hypertruck ERX system can achieve up to 1,000 miles of total range, leveraging the existing infrastructure of nearly 700 natural gas fueling stations nationwide, the companies said.

“Working with Hyliion to achieve this certification is a milestone in providing another solution towards lowering emissions,” said J. Michael Taylor, general manager, propulsion systems strategy at Cummins Inc. “We are excited to combine technologies and offer the value that comes from the natural gas ISX12N in the Hypertruck ERX electric powertrain for customers needing solutions to achieve sustainability goals.”

Initial deliveries of the Hypertruck ERX powertrain with the ISX12N Cummins natural gas engine will occur before the year’s end, and Hyliion is currently accepting orders for the system.

SEMA member companies and automotive enthusiasts have come out in strong opposition to the California Air Resources Board’s (CARB) “Advanced Clean Cars II” (ACC II) regulation that would ban the sale of new internal combustion engine motor vehicles by 2035. Specialty aftermarket businesses and industry supporters sent over 5,000 letters to the U.S. EPA expressing opposition to the agency providing California a Clean Air Act waiver, which is required for ACC II to take effect. Industry and enthusiasts alike have united in opposition to California’s Zero Emissions Vehicle (ZEV) mandate that they said would adversely impact automotive businesses, their employees and millions of automotive enthusiasts.
