That's not at all true. Critical structural parts, such as B-pillars, are almost always made of forged or hot-stamped high-strength steels. And this is true even in cheap vehicles like the 2007 Dodge Caliber. See, e.g.: https://i.imgur.com/N399WLV.png https://i.imgur.com/N399WLV.png
I think that the casting technique mentioned in the article is primarily, or entirely, for non-structural parts that would otherwise be made of something akin to mild steel.
- Robotbeat 4y agoNo, the aluminum injection castings are structural. Using high pressure injection helps keep the voids low or non-existent compared to atmospheric pressure sand casting, for instance, which significantly improves performance (improving strength and toughness).
- MichaelZuo 4y agoNo part of significant size will be forged in a sub $100k car. As another user mentioned, even the cheapest forged wheels are >>$1k each.
