With Aptera’s 2e electric vehicle headed into the lab for final validation testing in the Automotive X-Prize’s side-by-side class (against only four other vehicles), the company’s latest newsletter is looking to the recent past and the future. Sure, there’s the obligatory X-Prize update, but the more interesting bits of information come from an interview with Dave Oakley, Aptera’s VP of Manufacturing.
Apparently, Aptera used the somewhat controversial Six Sigma method to optimize the new composite material on the 2e. Oakley said the original material on the 2e wasn’t perfect in both appearance and consistency. He told his in-house writer:
We applied Six Sigma to optimize the materials we started with, which led us to change those materials to make them more production-worthy… The new material is made of sandwich core construction, which is a combination of several dry reinforced materials molded together using a resin. This construction gives us a material with a form similar to an I-beam running the length of the surface. The result is a material that is three to four times as strong as steel, yet the body is so lightweight a couple of people can lift it.
