This article is misleading. If a car crash is bad enough that it damages the frame of a car, it's going to get totalled anyway. So either way it's going to go to a junk yard and get slowly parted out.
Not on unibody cars. There isn't a big increase in frame area in this car versus any other unibody out there. The difference here is the unibody isn't actually a unibody, it's a multipart unibody that is bolted together. A standard unibody, which is just about everything on the road today that isn't a pickup truck, is all three of those frame pieces you see in that picuture, but as one giant piece. That big piece of metal you are normally used to seeing in car assembly photos. There are no frame rails under it. The unibody being split into segments is the first real change to the unibody design since GM started using it in the 80's.
Not necessarily. On some vehicles the exterior panels are part of the frame and you may only have cosmetic damage but fixing it would costs tens of thousands.
There is no affordable car today that you can make any money today that you need to use. They require money in order to maintain it well enough to use.
Tires are expensive. Gas is expensive. You've got filters and oils and fluids to replace, and headlamps. Without the required disposables, a car is basically useless.
A house without running water, or power, or natural gas, or a furnace filter, or water softener, or lightbulbs, or toilet paper, etc. still provides shelter without all of those things.
A car gets you from point a to point b until it doesn't. At that point it's disposed of.
I agree, I think the real problem is the cost to maintain one and the economics around it. For too long the expectation was to put as little money as possible into maintaining it and getting a new one some years later. We need to stop making them the massive status symbols they've become.
Won't be a problem because more and more people don't want a car.
Car manufacturers know this and that's why they are focusing on self-driving cars. Taxis will be replaced by robo-taxis owned by manufacturers and private firms.
Within 20 years, will be like a luxury like owning a horse
Such a scenario would be to Toyota's benefit however, as an unrepairable car will still need replacement—potentially with a new car. Repairability is something the automotive industry has directly combated in recent years, with a Toyota-backed industry group sponsoring a scare campaign to (unsuccessfully) undermine a right-to-repair bill. Car companies make their money from selling new cars, not keeping old ones on the road. If cast bodies serve that end better than those stitched together, it'd be no surprise to see them become the industry standard.
Car companies need their cars to hold their value secondhand so that the people who buy their new cars can afford to replace them more often. The right to repair stuff is about forcing people to use their dealerships for repairs.
No idea what Toyota's plan is for body repairs but destroying their second-hand market is probably not a part of it.
Also, don't car manufacturers have ridiculous margins on original spare parts? I thought they made a lot of money on those over the pretty long lifetime of the vehicles.
Yeah, I mean the main advantages for Toyota are clear and massive. Huge cuts in assembly time and factory floor space. Any effect on the second hand market is likely not intended, but also almost certainly worth the savings made, as far as they're concerned.
If you have a large cast part you could do the same thing as you do with a frame or body panel now. As long as there’s a replacement cast part ready, it is lots of work in some cases, so it’s less “impossible to repair” and more accurately “cost prohibitive to repair”
I wouldn't even say cost prohibitive. Imagine if you could just swap on a whole new front end after a car crash. Currently, it takes bodywork at hundreds of dollars per hour to repair damaged body panels while this could severely reduce that time and cost.
Has anyone come up with a guess on the cost of swapping out an entire cast body section vs replacing or refurbishing the parts that would be there without the cast?
I think point is without the cast body section you could just replace broken parts which may be significantly less. In practice though I don't think it matters that much. Small accidents hopefully don't damage the frame and if they do it's often a bit dubious repairing it.
Yeah, I think once you get to the point where the car needs the frame worked on, it's probably going to get scrapped whether it has a cast frame or not.
The expense of repairing frame damage is already really high and, in my personal experience with a couple cars that had frame damage from being hit, the insurance counts it as a total loss every time. I don't suspect the average car owner is going to repair that kind of damage when it would be cheaper to just replace the entire vehicle. An enthusiast or someone with a sentimental bond with it, and has the money for it, might choose to repair it tho.
Gigacasting saves car companies money, it doesn't save car owners money. For the manufacturer it reduces their bill of materials and time take to assemble a vehicle. They might save a couple of hundred bucks. Possibly.
For the owner, it increases the risk that a small collision runs a fracture along the body of their car which is then basically impossible to repair and the entire vehicle is a writeoff. Castings could potentially have sacrificial points where some kinds of damage could be ground off and replaced with stamped metal but even if that were so, it's still less repairable than if the entire frame of the car were assembled of stamped metal.
It's more than a couple hundred dollars. Production time will drop from 10 to 5 hours per car. The tooling and multiple parts eliminated from large casts will save thousands.
I doubt it is thousands since most plants are automated, but even assuming it were, it's the consumer who suffers when their car is basically disposable after a crash.
this is just more outsourcing the costs onto the public and privatizing the profits for short term gain, they're hoping the entire industry folds in on this but I am absolutely not buying a car where some asshole bumping into my parked car will result in me having to replace the whole front third.
I'm still building it, but be prepared to buy a lot of tools and parts if you don't have experience already. I'm waiting on some electrical connectors to connect the controller and battery, and I had to get a metal file to file down the front dropout because it was ever so slightly too small to fit the motor on.
