The 2015 Malibu achieved a 5-Star overall NHTSA safety rating. The Malibu has 10 air bags that includes knee air bags for the driver and front passenger. In addition to the airbags, the body structure is extremely strong and has an ultra-high-strength steel safety cage.
Checkout the screenshot from Moditech’s Crash Recovery System. Crash Recovery System clearly indicates that the body structure has very strong steel. The A-Pillar, B-Pillar, and the rocker panels are highlighted in blue indicating reinforced stronger steel.
