A connection arrangement 1 between a casting 2 made of light metal and a steel profile 3, wherein the steel profile 3 is indirectly connected to the casting 2 by way of a metallic coupling element 4 having an open or a closed profile. One end of the coupling element is at least partially expanded and over-molded. Automotive components composed of one or more castings 2 and steel profiles 3 can be produced with this type of connection arrangement, which can have an arbitrarily complex structure. In a suitable manufacturing process, the coupling element 4 can first be over-molded by a casting 2, which is constructed as a hollow component employing a casting core 11, and thereafter be materially connected to the steel profile, thus avoiding direct connection between the steel profile 3 and the casting 2.
