Beschreibung
Zusammenfassung:	A vehicle assembly includes a roof structure having a roof panel formed of aluminum or an aluminum-based alloy and a vehicle body formed of steel or a steel alloy supporting the roof structure. The vehicle body includes a pair of laterally spaced side panels, a front roof rail and a rear roof rail. A bracket formed of steel or a steel alloy secures the roof structure to the vehicle body. The bracket has a first portion fastened to the roof panel and a second portion extending away from the roof structure and welded to the vehicle body. An adhesive located inward of the connection of the vehicle body and second portion of the bracket bonds the second portion to the vehicle body. The adhesive seals the connection of the roof panel and bracket first portion and reduces thermal distortion of the attached roof panel relative to the vehicle body.
