Man I'm just perpetually baffled at how stupid this thing is. It doesn't look like there's much clearance at all between the caliper and the wheel either, so it may not even be practical to get something in a less stupid size for winter tyres or whatever. I'm sure Tesla have all this sorted though and it's not just a half baked piece of trash.

Cyber truck is like 1999 yahoo chatroom cyber sex. Dumb, pointless and ultimately disappointing. Also, I just learned of the existence of "VinFast" automobiles. There appears to be a dealer in my city. https://en.wikipedia.org/wiki/VinFast

 To sell an EV car in the US you just have to submit what, three units for crash testing? Or is that even required? Presumably you get an emissions testing waiver Edit: apparently you don't need to have it independently tested, you can just submit results from internal testing. Apparently land Rover does this with all of their vehicles, and Mazda does it with the Miata, and a pretty wide range of cars really https://www.consumerreports.org/car-safety/some-cars-will-never-be-crash-tested-crash-test-ratings/ Hadlock fucked around with this message at 01:28 on Aug 31, 2023 |

I'm shocked you've never heard of them, why they're the 3rd most valuable car company in the world! quote:Aug 28 (Reuters) - Shares of Vietnamese electric-vehicle maker Vinfast surged 21% on Monday, extending a rally from last week that more than quadrupled its market value to $160 billion. Wait, sorry, that was 3 days ago. quote:VinFast shares are on the move again today, up 11% in early trade but slipping again to a nearly 9% loss in midday trade. On Tuesday, the stock shed a whopping 44%, snapping a six-day winning streak and losing $83 billion in market cap in one day. But that’s not the whole story: VinFast shares have climbed almost 700% since the company listed on Aug. 15 via a SPAC merger with Black Spade Acquisition. Something's fucky.

The wheels are so big because it's heavy as gently caress and probably needs huge rotors to stop the brakes from immediately cooking so it's not necessarily that the wheels are the part that is stupid. I don't know poo poo about off-road tires but a 315 track seems ridiculously wide. Maybe to spread the weight out more?

I was curious so I looked up the hummer ev since it's an absolutely huge abomination of a car, and it runs a 305 70 r18. No official weight for the cybertruck from what I can see, but estimates vary from a bit lighter to over a ton lighter. Tesla's have had pretty poor repeated braking performance from what I've read so maybe they're trying to change that with huge rotors. I don't know poo poo either, but that tread pattern looks pretty mild compared to any all terrains I've seen, and there were the photos floating around a while ago of it needing ramps to get over a normal curb outside the Tesla factory so I really doubt they've put much thought into the off-road performance.

They're big, but the funny thing to me is that they're almost identical in size to 35x12.5R20s, which are vastly more common. Size comparison:  Discount has 61 options in 35x12.5R20, which is an absolute shitload for a truck tire - even my common-as-hell 33x12.5R15 has about half that.

I saw an article recently, not sure if it was this one https://electrek.co/2022/09/01/tire-makers-adapting-business-ev-revolution/ Apparently EV tires have slightly different requirements, both a heavier load, and loads more torque from at rest can cause EV tires to wear double digit % faster quote:Since EVs perform differently than gas-powered vehicles (that feeling of instant torque), traditional tires are not ideal. In fact, the company claimed EVs could wear standard tires 30% faster. The tread looks pretty drat close to the wrangler territory mt but there are some slight differences Hadlock fucked around with this message at 04:42 on Aug 31, 2023 |

VinFast gave cars to Vietnamese influencers who then posted critical reviews of them and were pointing out all sorts of flaws. VinFast got the authorities to arrest the social media influencers but after public outcry they were all released without charges.

KillHour posted:Is measuring tires in inches a truck thing? I've never owned a car with tire measurements like that. Yeah, but even when the "same" size tire is available as either a metric or "flotation" tire size, the construction between the two might be different. For example, picking a Toyo Open Country A/T III that's available in both 31x10.5R15 and 265/75R15 (which are nearly identical) - the flotation tire weighs five pounds more, has 3/32" more tread depth, a higher maximum pressure, a different load rating, and no UTQG scoring.

It feels incomplete. If they had just spent a little more time on some details like tuning the suspension and improving the software it could be alright. It does need to be less expensive, though. Nobody is going to pay Ioniq 5/Mach-E/Model Y money for this.

I really think Toyota has it right as basically the only car company I can think of without plans for a full ev: the plug in hybrid is the smarter approach. Most trips are 40 to 50 miles, but can sometimes be hundreds of miles in a day (road trip, emergency evacuation, etc). So put a little gas engine in there, as a treat. The energy density of gas means it isn’t a big deal to haul around 2-300 miles of “just in case” energy vs the cost of doing that with thousands of pounds of batteries even if it means you have to haul an extra engine along with it Even if we moved to something more sustainable like flex fuel or idk pure ethanol and the price went up to 20 or 30 dollars a gallon it still wouldn’t make much difference since the amortized cost would remain low: you only need that range a few times a year and that’s when you pay those high prices

I think you're ignoring a pretty significant cost to the manufacturer in complexity. Sure, right now a large battery is expensive, but costs are probably going to come down over time. Meanwhile, in a PHEV you're still putting in a bunch of systems related to an ICE powertrain, plus EV powertrain systems, plus the complexity of integration, in order to save on battery costs. You've got packaging nightmares, manufacturing complexity, and a huge number of additional components.

I thought that parallel plug-in hybrids aren’t designed to be constantly used as short-range EVs. A serial hybrid seems more suited to it but I couldn’t find a list of those quickly. There was the Volt which is dead, I think the BMW i3, and… ?

The Volt wasn't solely a series hybrid anyways. It had a mechanical drive connection which it could use in some regimes (high speed driving mostly). Similar to the modern Honda/Acura hybrids that are mostly series with a clutched highway gear.

That's leveraging Toyota scale and capability - they could do a pure EV way cheaper. Tesla BOM cost on the model 3 is a variable target but it's like somewhere in the low 30,000s and that's with Tesla being a marginally competent manufacturing company and with a huge and high cost battery.

And keep in mind that throwing these thousands of pounds into your car just lessens range anxiety it doesn’t eliminate it. The lucid air I think is the longest range ev currently on the market. Ignoring the price for a moment (we’ll pretend the battery price went down) it has a range of about 425 miles under what I imagine are extremely ideal conditions (what if I’m taking that road trip in the cold, or there’s a headwind?). I can easily do more than double that on a full day of driving. Sure I could eat a meal while the car is charging but now I’m sort of planning my day around the range of my car. Unless something changes with charge times it’s hard to beat pulling over for 5 minutes to refill to max range

If you wanna grind out 1k miles/day yeah, an EV probably isn't for you. I don't think that means that the future is based on PHEVs alone since that is a rare use case.

Just to throw my 2c on the topic, i've just purchased an EV with a 350km range but i do less than 30 daily, with chargers at the office. Every trip longer than 100km i always pick the train or a plane, so i don't care much about absolute range.

The point I’m trying to make is it’s a rare use for most people, but it does happen. If you drive 500 miles a day once a year, an ev is a pain on that day. I would buy a plug-in hybrid for that reason alone and I think people are wrong to categorize worrying about range anxiety as silly. Why carry an epipen? You barely ever have allergic reactions!

because at some point lugging around that gasoline engine is gonna cost you like ten grand and people won't pay for it. I'm not really intending to buy an EV but I think you're significantly overstating the difficulty of doing 500 miles in an EV. And as infrastructure build out continues, and performance in DCFC improves, that trip gets easier and quicker. also dude: you are loving deranged, dying of an allergic reaction is not the same thing as having to charge your car for 45 minutes

Even at trickle charge speed, a night of sleep is a full battery. A lot of range anxiety comes from the general lack of charging infrastructure and people's unfamiliarity with it. We don't have range anxiety about IC cars because gas stations are ubiquitous and we're familiar with them. Few people know off hand where charging points are and are thus worried about what they'll do if the battery gets low. Yes, there are apps that tell you where they are etc., but that's all part of the whole electric car ecosystem that people have to get used to.
