A front rail configured to be supported by a vehicle frame includes a tubular body formed by a roll-formed high-strength metal and configured to undergo axial loading during a front vehicle impact. The high-strength metal sheet defines a cross-sectional shape along a length of the tubular body. The tubular body includes a central wall extending from a first side wall to a second side wall defining at least a first longitudinal channel and a second longitudinal channel. A groove is disposed in first side wall of the tubular body and extends longitudinally along at least a portion of the length of the tubular body to stiffen the tubular body. A hole extends through the first side wall of the tubular body proximate the groove and is configured as a bend initiator.
