The World’s First Flex Fuel Plug-in Hybrid Electric Vehicle


RFA is combining technologies to meet tomorrow’s goals today!


The goals of the future are being set, and oftentimes with a specific vehicle in mind: battery electric vehicles (BEV). As we all know, their penetration into the overall fleet will take decades as the vehicles are introduced and infrastructure is built, but that doesn’t mean the goal should wait. The combination of a flex fuel vehicle (FFV) and a BEV is possible today.

RFA purchased a new 2022 Ford Escape Plug-in Hybrid Electric Vehicle (PHEV) as our latest vehicle project. The concept is to use this vehicle to demonstrate that ethanol (E85) and electricity can jointly power our vehicles today. In fact, in some cases, the E85 portion has a lower carbon intensity, along with cost, than pure electric.


Upon purchase, students at the University of Nebraska’s Husker Motorsports Team assisted RFA’s Robert White with the conversion to flex fuel. This process used a conversion kit from eFlexFuel. The process took under an hour to complete, and now the vehicle can run on any blend from regular unleaded (E10 or E15) to E30 or E85. Click here for photos of this process.


The vehicle was then transported to the University of California at Riverside for emissions testing on E10, E30 and E85. The emissions testing was completed at the Center of Environment Research & Technology. This testing took more than a month to complete. From there, the vehicle toured the countryside logging data miles for cost comparisons, convenience analysis, and more.  In the summer of 2023, a full lifecycle analysis was completed by researchers at the University of Illinois Chicago and Life Cycle Associates that compared full-battery electric vehicles, regular internal combustion engines, and our new creation, the Flex Fuel EV.


This slide deck explains the what and why of the project along with positive initial results on fuel economy and emissions.
