Yes, because the Model 3 incorporates quite a bit of aluminum in the body. This is good for weight savings, but more difficult to work with.
The root cause is that batteries are too heavy so other components must be made lighter.
- rootusrootus 3y agoThe Model S has a fair amount of aluminum in the body (about 400 pounds or so, IIRC). The Model 3 is much more biased towards steel for most of the body, due to cost.

- Underphil 3y agoDo you know why it's harder to work with? My untrained brain would have assumed it was easier, what with it being more malleable.
- userbinator 3y agoAluminum is more brittle and far more difficult to weld than steel.
- WarOnPrivacy 3y agoBut we're comparing to fiberglass, not steel.
- Smoosh 3y agoPossibly due to Work Hardening. https://en.wikipedia.org/wiki/Work_hardening https://en.wikipedia.org/wiki/Work_hardening
- neltnerb 3y agoTo an extent, for banging into shapes, but it's challenging to add more material to it if needed. None of the options are especially good compared to welding, though that's just my opinion (compared to fasteners - size, brazing - high temperature but maybe). Other materials have their own issues, but if you cast large pieces of anything you also make it super expensive to replace parts that can't be repaired onsite.
- mvdtnz 3y agoA lot of guys are telling you it's because it the workability of aluminium which is purified bullshit. Panelbeaters rarely work panels nowadays, they replace them. The problem with Tesla is that they're gaping assholes when it comes to supplying parts to third party repairers. Repairing Teslas is expensive because that's how Tesla wants it to be.
