John, yes 'unboxed' does mean the vehicle body in a half dozen parts. Gigacasting does give good dimensional control, so maybe a mix of 4,000 and 6,000 tonne presses for a large vehicle. The speed of casting is tied to the weight of the moving parts. Smaller parts with well-designed flow paths for the molten metal reduces press size, increases press speed. Tesla has built a mould making and milling die shop at Austin, and is installing a gigacast machine in the die shop to make moulds and test them for performance and dimensional accuracy. Perhaps it will export moulds to its Berlin and Shanghai plants.

Regarding the anti Giga casting argument from the steel industry : “they saw it coming before Tesla made it feasible” 😂 yeah sure, and they could’ve landed rockets vertically but preferred staying in their lane. Get a clue!

@@mowensmd the Chinese own Idra. Castings are rigid - as in brittle. Steel can be stretched back to spec dimensions. Hertz don't want to know. Lifetime repair warranties stress insurance underwriters. Elon Musk always uses updated old tech.... Russian rocket engines to castings........he exploits opportunities - and the gullible who swallow whole every Tesla promotion.

The tech was sitting on Sandy Munro's floor for over 15 years. They didn't WANT to do it. They don't innovate unless they're forced to the edge of a cliff.

Sandy Munro has had a gigacasting sitting on his showroom floor for 15 years. The OEMs were too lazy and stupid to take up the idea. Saaaaad. That's why they are going extinct.

2016 Cadillac CT6 had aluminum casting structure.

Toyota is still king of all OEMs and they the always take most conservative approach. In the end, people want a reliable transport that's cheap to maintain and operate. This is something that Tesla struggles with because as soon as you need to insure, register, or repair the vehicle. The costs are astronomical.

@normt430 It doesn't. Look at the data. They aren't even top 10. If you account the number of recalls compared to the the volume of cars they produce Ford takes the crown. Tesla is #10 next to #9 Hyundai.

What about magnesium? That also might be a threat. Also it is not certain that gigacasting are more expensive to repair or even more likely to need repair vs a bunch of welded parts.

ZF and Tesla logos are on the CT steer-by-wire castings. US exceptionalism in part means that the US is the odd country out. The world needs a billion 2 and 4 wheel new vehicles a year, but the auto industry only produces 70 million 4-wheel vehicles per year due to size and power and resultant cost. If the French could make ~410 kg small car in 1938/39 using giga-cast aluminium body frame, surely someone can make an 800 kg EV with 20kW of motors, 20kWh of battery, front and rear steering, electromechanical brakes and 4WD (effectively vector steering) that has 'drive' packages front and rear that are two-part castings (top and bottom) that contain pairs of motors, planetary gears, brakes and electrically driven steering racks. Inverters for all motors could live in an electronics package under the hood - the drive pachage would be dumb to reduce parts and increase life, while the electronics package under the hood is easily upgraded. Mechanically, there would be 4 half-shafts and 4 steering rods (one each per wheel). The same drive package could be used front and rear. Average energy use for a two-tonne EV doing the EPA duty cycle is only about 10 kW, so two that in a vehicle 40% of the weight will be plenty.

Well, Tesla uses a steel battery box and laser welding already, and even does laser welding of its cells. Perhaps SpaceX gigacasts the top of its Raptor engines.

I’m not sure using the Lotus as a reference is a good idea. Based on KZbin reviews the traction and stability control is not the best. See Carwow for one example.

@AutolineDetroit Ай бұрын

We agree. We've driven the Lotus Eletre and it's not the greatest chassis tuning. But that's probably more of a problem with the people who did the tuning, not the cubiX system.
