Cummins, Hyliion partner to optimize natural gas, electric powertrain

June 29, 2022
Cummins’ ISX12N will be optimized with Hyliion’s electric range extender powertrain solution, so the truck can refuel using the 700 natural gas stations across North America.

Hybrid-electric powertrain startup Hyliion is joining forces with Cummins Inc. to optimize the Cummins natural gas engine as the generator for the Hypertruck ERX powertrain.

Together, the companies plan to obtain environmental certifications for Cummins’ natural gas internal combustion engines to be used in Hyliion’s Hypertruck ERX powertrain. The Hyliion Hypertruck ERX is an electric range extender semi-truck powertrain solution using onboard power generation to recharge the batteries.

“We are excited to work with Hyliion to offer this range extender electric and natural gas powertrain in the North America heavy-duty truck market,” said J. Michael Taylor, general manager of Global Powertrain Integration at Cummins. “Natural gas solutions are an integral part of our journey towards zero emissions. Integrating our engine with the Hyliion Hypertruck ERX solution is key to offering our customers a portfolio of powertrains across many fuel options to meet their sustainability goals.” 

The Hyliion Hypertruck ERX offers 75 miles of electric range to qualify for credits under the California Air Resources Board’s upcoming zero-emission vehicle mandates and can achieve up to 1,000 miles of full range through the generator. Cummins’ ISX12N will be optimized with the Hyliion Hypertruck ERX so that it can use the existing 700 natural gas stations across North America for refueling.

“With the shared goal of making commercial trucking more sustainable, our collaboration with Cummins will undoubtedly benefit the transportation industry. Attaining EPA and CARB certifications is a key step on our production path, and I look forward to working with Cummins to get our Hypertruck ERX on the road and making a positive impact on the environment,” said Thomas Healy, founder and CEO of Hyliion.

Start of production for the Hypertruck ERX with the ISX12N Cummins natural gas power is anticipated to begin in late 2023.
