Honda unveiled the relaunch of its Acura NSX at the North American International Auto Show in January.


was the first all-aluminum produc- tion car, the new NSX will feature ‘world’s-first materials’ and innova- tive construction,” said Ted Klaus, Chief Engineer and Global Devel- opment Leader, NSX, at the North American International Auto Show in January. “A multi-material chassis comprised of an aluminum intensive space frame, with strategic use of


ultra-high-strength steel, carbon fiber and all-aluminum suspension.” Te space-frame concept primarily


utilizes extruded aluminum lengths and cast aluminum nodes serving as joints. In the early design stages, Hon- da engineers had small cast aluminum joints in the space frame but outside of the crash zones. Tey saw an opportu- nity for additional part consolidation

and space-frame performance if they could design the castings within the crash zone. To do this, the cast parts would have to match the properties of the surrounding extrusions (265-295 MPa UTS, 175-205 MPa YS, > 12% elongation). Consistency of proper- ties within the crash zone is critical in establishing a repeatable crash absorption mode, according to Philip
