Seems like there's been relatively less attention on the 48V/800V architecture and the Ethernet comms/steer by wire setup, but I think those are what make this particular vehicle quite interesting. Up until recently I think 48V power electronics have been fairly rare outside of telecom/other high cost situations, but I suppose one major difference is that at 48V, transformer-based DC-DC conversion is usually a better…

I am curious what cybertruck will charge like at existing superchargers that max out at 400V. GM's clever solution is to present the battery pack as 2 400V packs. It does pose some very tricky pack balancing requirements though. Other 800V cars charge quite poorly on 400V stations, usually with a hard cap at much lower than the potential max charge due to inverter limits.

Cybertruck does the pack splitting thing like the GM Ultium vehicles:

It will be interesting to see Tesla's rollout of 800V stations, so far they don't have any within their own network.

It means where you put the steering wheel doesn't have to have a firewall penetration and mechanical linkage through to the engines. That's a lot of mechanical joints which need to be continuous, and need greasing, sealing and have limits on relative angles between them that you don't need - as well as they have to have enough strength to transmit the forces involved. By contrast, with steer-by-wire your system is es…

Big rigs used to not have power steering, i think with adrenaline you'll be able to steer. I do concede that the power steering fighting you would be bad

I just want feedback from the road, wires don't give me that

4x4 in the summer? Yeah, not so much. 4x4 in areas with real winters with ice and hills and mountains? Yes indeed that is quite an improvement.

I won't deny it can be useful, but it's still not needed . I grew up in Wisconsin (which certainly qualifies as real winters) and you can get by just fine in the winter without 4x4. The biggest problem by far in the winter isn't traction, it's being able to stop when you need to stop. AWD doesn't help with that at all.

The traction control is also significantly better on EVs because you have much quicker response times. I've made it up to ski fields in a RWD Tesla Model 3 with summer tires easily.

They do it on the Model 3 as well. The Model 3 Performance is 1Ft rollout (3.1s) but the Dual Motor Long Range is not. Car and driver tested it to 3.99 when Tesla says ~4.2s

At least the lying is in the slow direction rather than the fast direction.

No, its the same direction again. The 3.99 achieved by car and driver is for the dual motor mid range car, which tesla quote at 4.2. Tesla quote the top spec Performance at 3.1 seconds to 60 with roll out subtraction only on the fastest car again.

Car and Driver however also subtract rollout in their tests, so again its not a valid comparison to the 4.2 figure from Tesla with rollout included, making things even more confusing here.

Everyone with a brain knows this is a vanity project by a very rich person who can do whatever he wants. The success doesn't matter. I don't think that's a good or bad thing, it's just a thing. If anything it demonstrates what a bored rich nerd can do for fun. I guess I might do something like that if I had billions to throw around, maybe I'd just make one for myself though, and not an entire product line that would…

I'm no defender of Musk, but he (and the people working for him) seem pretty serious about making Tesla and SpaceX enduring companies. And honestly, if I had billions to throw around I might want to build rockets and replace ICE cars too. Having said that, I simply cannot contort myself enough to pretend he is not deliberately tanking Twitter.

I don't disagree with you at all. He has hired very brilliant people and it is easy to list a dozen things that would have taken decades or more to happen if he hadn't gone full nerd-billionaire and thrown gobs of money at his passions. Whether or not Musk himself is smart is besides the point: he took his childhood dreams and spent big money to make them happen. Who wouldn't do that?

That being said I think he's an evil POS, and I think the biggest struggle popular culture is having is that of simple naratives: people are all-or-nothing, black-or-white. It's possible someone can be a crapoid earthling and still cause beneficial things to happen in spite of who they are. That's a hard pill to swallow from either direction, and I have a very tough time with it! I personally don't think the ends justify the means here, but that's because of where I set my bar. Other bars may vary.

Interesting that the marketing image on that page is clearly meant to suggest driving around on Mars. I think it is clear from the design and marketing that this truck is meant as a fashion statement not a work vehicle. It will be interesting to see if it catches on. I like some of the ideas used in the vehicle's construction, though I do not like how dangerous it appears to be for pedestrians. If I made a prediction…

I do think the raw metal color of the truck looks better on mars background than typical black tar roadways.

That's called the 5-to-60 time. Car enthusiasts benchmark both 0-to-60 and 5-to-60 because that rollout can change the behavior of various cars. What we have here is Tesla taking the 5-to-60 time and pretending its a 0-to-60 time. Rollout is fine and all, just ya know, be honest about it. Call it a 5-to-60 time.

> Rollout is fine and all, just ya know, be honest about it. Call it a 5-to-60 time Are they not honest? It says so right in the spec quote. Why is "5-to-60" honest but "with rollout subtracted" dishonest? One is jargon and the other English, but I think you have to stretch really hard to read in an attempt to deceive here.

Subtracting rollout times from one car, but not all cars, presented in the same page as comparisons is inherently dishonest.

I'm pretty sure a lot of people making less than 150k buy $60k F-150s.

There’s a big difference between $60k and 100k.

My point is Cybertruck starts at $60, not $100k, and likely a majority of sales will happen closer to $60k than $100k. But I'd venture to guess that a majority of people buying even the $100k variant do qualify for the credit.

why do steer by wire at all? Is it cheaper somehow?

Allows you to vary the steering ratio dynamically (how many "turns" lock to lock). Means a lot less arm twiddling during lower speed maneuvers, and can gradually increase the ratio as speed increases. Traditional mechanically linked steering racks (electric or hydraulic) don't do this and are the same number of turns lock to lock regardless of speed - they can only dynamically vary the amount of power assist, not the…

BMW had this on mechanically linked system for 20 years. It's called "Active Steering" in their marketing speak.

Well this is sticking your head in the sand about it. People own trucks because while trucks might not be particularly good at some things, they're also not particularly bad at them. If you need to move large or heavy items occasionally, it's really handy having a truck...and the thing is, it won't be bad at doing car things either. To the specific example here, you also have the obvious missing part: people are havi…

These types of stats aren't much good without some measure of criticality. Even if you only rarely use the full functionality of a truck, if it's critical those times you do, it's probably worth owning. It's the same logic used to justify car ownership in areas with good public transportation; you're paying for a capability on demand, even if you're not always using it.

Also, not all trucks are good for towing. Pick-ups/utes are notorious for yielding where the cab meets the chassis, right in front of the bed, because they're designed to take a load in the bed, not at the rear of the vehicle. We don't tow with our truck for that very reason.
