2025 WM4
Work on our 2025 competitor is currently underway! Stay tuned!
2024 WM3
Just as every year with Formula Hybrid + Electric, 7220 Hunny, got completely gutted to make room for upgrades. We did everything to improve upon any shortcomings of our competition winning car. Notable changes included improvements to the cockpit, an improved ICE, a new accumulator, but many other changes were made in the name of chasing perfection.
Despite the countless hours spent on designing, building, implementing, and trouble-shooting, we were unfortunately unable to get the car running at competition. While we passed all mechanical and safety inspections, there was a fault within the electrical system that fused a wire with the chassis, rendering the EV system unusable and preventing us from passing electrical inspection.
2023 WM2
Every year our vehicle undergoes substantial changes to keep us at the forefront of our field. For the 2023 year, the vehicle was improved overall in many ways! We are proud to say that this iteration of the "7220 Hunny" took first place at competition in May!
Suspension & Chasis
From last years car, we have made changes in the rear spring rate as well as ride height to help keep our car optimally sprung and ultimately handle better. On the chassis side, the car was stripped to a bare frame, new brackets and tabs were welded and the chassis was reassembled to make room for other upgrades.
Electrical
Our electrical system also underwent extensive work since last years car. This included a complete new wiring harness for all systems to help weed out electrical gremlins as well as a custom dash designed to
better display necessary vehicle information.
Powertrain
​
For the 2023 season, we made substantial changes to the powertrain via: an upgraded mechanical shifter linkage along with a hydraulic pedal clutch to help improve shifting and feel compared the previous cable hand clutch and shifter, a change in gear ratio for the e-motor to increase the torque, upgraded cv joints and axles to reliably manage suspension travel better, and a new dual radiator and fan setup for both motors to increase thermal efficiency.
2022 WM1
Our first competitor in Formula SAE Hyrbid+Electric was the WM1 in 2022. Our main goal with this car was to make it to all of the inspections at competition. Not only did we accomplish this, but we were able to make it to the endurance race as well. We ended up taking home many lessons and ideas for next year, as well as second place overall.
