2019 BMW X4 Body Structure

Body Structure

The 2019 BMW X4 has higher-strength steels and some aluminum in the body-in-white. BMW used an increase in the proportion of aluminum as well as high-strength and ultra-high-strength grades of steel in the body structure. The diagram provided by BMW shows aluminum elements and the door rings, rocker rails extending back to the quarter panel, both kickpans, the suspension tunnel and a roof frame crossmember are among the ultra-high-strength steel parts. Multiphase steel elements include the floorpans and roof frame rails.

This has made the body structure more solid than ever, serving up benefits for both vehicle agility and occupant protection. Additionally, the car has a significantly lower center of gravity which enhances the Sports Activity Coupe’s cornering dynamics.”  A diagram provided by BMW shows aluminum elements including the strut towers and a small crossmember on the floor. Door rings, rocker rails extending back to the quarter panel, both kickpans, the suspension tunnel and a roof frame crossmember are among the ultra-high-strength steel parts. Multiphase steel elements include the floorpans and roof frame rails.
