In 2019, the team suffered a serious setback during manufacturing, severely limiting our testing time. Nonetheless, we persevered and successfully campaigned the WR-219 at FSAE Michigan, capping off a rebuilding year for the team.
An evolution of its predecessor, the 218c picked up where its older sibling left off. Further validation and improvements earned us 4th place in the design event, and increased our overall performance on track: the WR-218c finished FSAE Michigan in 8th place overall.
A revolutionary change with our third-generation monocoque, redesigned aerodynamic package and vehicle kinematics, and all-new Yamaha powertrain powered us to a 10th place finish at FSAE Michigan.
With heavy emphasis on achieving more vehicle testing time, the 219e vehicle featured key improvements to each of the major components of the powertrain: motors, inverters, and high voltage battery. The improvements include more reliable motor control, system efficiency characterization, and state of charge estimation for the battery.
The 218e featured a redesigned high voltage battery, student-designed motors and motor controllers, and custom high torque density compound planetary transmissions. The improved four-motor electric powertrain, paired with the hybrid monocoque and redesigned spaceframe, offered a 20% decrease in weight.
The first electric vehicle produced by Wisconsin Racing, the WR-217e was designed to share a monocoque with the WR-217c and utilize a bespoke rear frame design to contain the team's first-ever custom high voltage battery. The team earned 1st in the design event with this all-wheel-drive vehicle.
