Major New Propane Vehicle Models Now in Full Production


Two notable new propane autogas vehicle platforms – Freightliner Custom Chassis Corp.'s S2G medium-duty truck and Thomas Built Buses Inc.'s C2 school bus – are now in full production.

Both vehicles feature liquid propane injection systems from CleanFUEL USA, paired with Powertrain Integration's purpose-built 8.0-liter engine and Allison's 2300 series automatic transmission. The engine offers 495 ft.-lbs. of torque at 3,100 rpm and 339 hp at 4,100 rpm.

‘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,’ says 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.’

Both the S2G and C2 are backed by warranties and service programs, and they are certified by both the U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB).

CleanFUEL USA notes that its autogas fuel system is fully integrated at the OEMs' factories, requiring no aftermarket modifications.
