The outdated backside construction was changed with an aluminum sandwich plate, which will increase the efficiency when it comes to the underside impression, and likewise performs a key function within the semi-integral automobile idea. The designers had been in a position to take away the extra aspect deformation components and use the freed area for extra battery cells.

Additionally, as a result of improved backside impression efficiency of the sandwich flooring, the area required for the module mounting may very well be diminished. The creation of those further areas for battery cells allowed the designers to extend capability from 65 to 75 kWh, whereas retaining almost the identical outer dimensions because the group’s previous-generation battery pack.
