Optimizing the Body of the Tesla Model S

Published Technical Research in Aerodynamics & Aero-acoustics

 

Reducing wind-induced noise and increasing range are two major challenges faced by electric vehicle (EV) manufacturers. This research is a demonstration of how simple modifications in exterior vehicle geometry viz. the windshield and side mirrors, can have a significant impact on various performance indicators and offset the aforementioned challenges.

 

The implementation of such changes can be done in the design stage itself before moving on to Shape Development Testing & Manufacturing, thus serving as a Quality at the Source lean tool.

 

Various design iterations of a simplified Tesla Model S were modeled. Performing transient 3D computational fluid dynamic simulations using the k-ω and LES models, the drag coefficient, sound pressure level and driven range were documented for each case, with the highest percentage increase in theoretical driven range being 6.604%.
