In the 2019-2020 season, SAE announced a rule change that by the 2020-2021 season, every vehicle would have to be capable of sending power to all four wheels. Though COVID caused SAE to extend the rule that 4WD is not mandatory for the 2020-2021 season, we are tackling the problem head on and attempting to design and build our first 4WD vehicle this year. With this comes many new changes to the previous iterations of the design of our car. The main goal is to have a working 4WD vehicle and, though we are still researching new and better solutions to this design task, we have decided to move forward with specific design aspects. First, we will be running a chain drive rather than a gearcase and implement front and rear differentials, while continuing to use a CVT. We also plan to run a prop shaft through the cockpit of the car to the rear of the vehicle and run inboard mounted brakes in the front and rear. The final change we will implement is to mount the engine longitudinally. We hope that by executing these design changes, we will be able to have a running vehicle for the in person portion of competition that will hopefully be taking place in the late spring.
