Abstract
A front end assembly for a vehicle includes a U-shaped tubular structure, a body portion having a pair of laterally-spaced, longitudinally extending cowl sides, and, a pair of laterally-spaced A-pillar structures. The U-shaped tubular structure is secured to each A-pillar and each cowl side at longitudinally-spaced apart locations. The laterally-spaced connection points provide improved rigidity and reduce distortion.
