The all-new SKODA OCTAVIA: Intelligent material mix combines maximum strength and low weight
Large proportion of high-strength steels lowers weight and enhances safety The all-new OCTAVIA’s exceptionally strong body is above all the result of a high proportion of high-strength steels. While using only 26.3 per cent of so-called deep-drawn steel – mainly for surface components – 20.6 per cent of the body is made of ultra-high-strength hot-formed steel.
The tailor-rolled blank technology was first used by the Volkswagen Group in 2004 for the ŠKODA OCTAVIA II. The combination of the tailor-rolled blank process and hot forming was first used for the ŠKODA OCTAVIA III. The tailor-rolled blank allows for the production of parts with varying sheet thickness. In numerous areas that are also subject to such high stresses the Czech manufacturer relies on multi-phase steel (dual-phase steel), which shows a high mechanical strength after the forming process has been done, and as a result, it is very ductile and very strong. Multi-phase steel and ultra-high-strength steel account for almost 14 per cent of the body’s weight.
