As powertrain lead for the Model Year 2019 vehicle, I redesigned the motor and differential mounting and transmission system to be lighter and easier to access.
Reduced system mass by 5 kg (>20%) using structural hand calculations in Excel and FEA in Solidworks Simulation
Manufactured components out of 7075 aluminum on CNC mill and lathe, including precision bearing surfaces
Improved serviceability by allowing the motor and differential to be installed and removed independently
Verified sprocket strength with empirical hardness test
Designed and manufactured welding jig to minimize chain misalignment
