The use of high-strength aluminium extrusions offers a 5% weight reduction compared to KTX-Sancheon, and the body has improved sound insulation.
Ferrari has launched the second teaser video of the 620, their 599 replacement.
In the video, there are quite a few processes between hot, molten aluminum alloy being poured into forms and an actual finished car: stamping, lamination, extrusion, etc.
