Under a new partnership with CleanFUEL USA, Allied Specialty Vehicles will expand its alt-fuel line, which currently includes Collins propane school buses.
Allied Specialty Vehicles (ASV) will expand its line of alternative-fuel vehicles under a new partnership with propane autogas technology supplier CleanFUEL USA.
ASV manufactures a variety of vehicles for the commercial, fire and emergency, and recreation markets. Among its brands is Collins Bus, which has already been offering propane Type A school buses with CleanFUEL.
“ASV has a long relationship working with CleanFUEL USA on propane autogas fleet installations for Type A school buses at Collins Bus,” ASV President and CEO Tim Sullivan said. “Expanding this relationship across all ASV vehicle brands will increase the breadth of propane autogas systems we can offer to our customers.”
The partnership agreement calls for CleanFUEL’s propane autogas systems currently installed by third-party upfitters to be transitioned to ASV factory-certified installations. Sullivan said that this change will offer customers a full OEM warranty and will increase installation efficiency and improve overall quality control.
Also, the two companies will work together to develop customer service centers that will offer spare parts and maintenance services for a full suite of CleanFUEL propane autogas systems for multiple ASV product lines and their customers.
“We consistently hear requests from ASV fleet customers — those who run shuttle and transit buses, terminal trucks and emergency vehicles, for instance — looking for propane autogas options,” said Curtis Donaldson, founder and managing partner of CleanFUEL USA. “We are thrilled to partner with ASV to meet the needs of customers throughout the U.S. and abroad seeking the benefits of propane autogas.”
Additional vehicle platforms, relative to ASV, are expected to be incorporated into the current OEM and aftermarket offerings provided by CleanFUEL.
