The University of Tennessee, Knoxville's (UTK) EcoCAR 2 team developed a Series-Parallel Plug-In Hybrid Electric Vehicle (PHEV) that utilizes E85 fuel. The vehicle was developed and modeled in Year One of the EcoCAR 2 competition. The team has spent Year Two refining the theoretical design from Year One and implementing the design into a working mule vehicle. The developed architecture has been integrated into a 2013 Chevrolet Malibu, which was donated by General Motors. The team focused on strengthening the replacement and modified components, integrating the new vehicle components, bench testing the vehicle controller and implementing the entire design into a working vehicle.
