High-Strength Aluminum B-Pillar

The B-Pillar is one of the most complex parts of the vehicle structure. Because of its importance in both integrity and safety, it has traditionally been very heavy. Alumobility aimed to replace this component in order to lightweight the vehicle without compromising on its core requirements.

To test our premise, we used a popular mass production electric vehicle, designing high-strength aluminum B-Pillars to test side-by-side with the current steel solution. By using high-strength 6XXX aluminum alloys, Alumobility provides a path to lightweighting in important safety areas. In addition, 6XXX alloys are compatible with other aluminum alloys used on production vehicles to simplify end-of-life recycling.


  • Up to 35% weight savings
  • Same performance within the existing vehicle package space
