CleanFUEL USA announced full production of a Freigtliner Custom Chassis S2G medium-truck powered by its liquid propane injection (LPI) system. According to the company, the CleanFUEL USA LPI propane autogas fuel system is fully integrated and factory-installed, requiring no aftermarket modifications. The vehicle is EPA and CARB certified.

“We are ecstatic that the S2G and C2 are in full production, as demand is strong in the fleet industry for propane-powered solutions that meet these two vehicles’ market needs,” said Curtis Donaldson, founder and managing director of CleanFUEL USA. “With a significant order bank and ever-increasing customer interest, the potential for both products is huge.”

The vehicle is powered by an 8-liter purpose-built engine by Powertrain Integration and an Allison 2300 automatic transmission with PTO provision. The engine offers 495 ft.-lbs. of torque at 3,100 RPM and 339 HP at 4,100 RPM.
