The 2022 Ford Mustang Mach E is a completely electric vehicle. One trend among Battery Electric Vehicles (BEV) is strong steel in the rocker panels and other areas to protect the battery pack. The martensite and press hardened steels we commonly find in the B-pillars are used in the rocker panels. Take a look at the images below presented in the 2021 Great Designs In Steel event last May.
