I'm sure there's some cases where that might be true or it's not practical for other reasons (I'm not an automotive engineer or anything), but remember, the 3 has ~70 parts welded together for this same area of the car, so welds themselves are not fundamentally bad.
- thesimp 6y agoJust as the BMW i3 the Alfa Romeo 4C also has a carbon fiber monocoque: https://www.toraytac.com/media/story/XkKY/Alfa-Romeo-4C-Monocoque https://www.toraytac.com/media/story/XkKY/Alfa-Romeo-4C-Mono.... And Alfa Romeo has published a 162 page manual for bodyshops on how to do repairs. The PDF is out there in the internet for people that want to know the technical details.
- MaxikCZ 6y agoI dont think the main concern here is that the new part would be welded in. When the car is in design process, each weld is carefully calculated to provide the exact binding force at the precise location. In case of accident, the car is modeled to crumble just right to absorb maximum energy without compromising cabin space, thus protecting occupants. The process of cutting out and welding in parts almost always means altering the stiffness of such bonds (and/or moving the bonds to different locations), which can be very dangerous in the event of accident
