It's the fastest EV lap currently.

On the one hand this is quite an achievement, but on the other hand it shows that EVs are not (yet) superior to ICEs in every aspect except range.

I was watching the U9 speed record and the driver only really puts his foot down for 20 seconds or so. I doubt the car can sustain that power for a whole lap without something going wrong - overheating or flat battery or something.

The downforce to weight ratio is quite different between the U9 and Porsche also. Apparently the Porsche weighed 850kg and probably produced as much as that or more in downforce. The U9 is more like 2500kg and not especially downforce orientated.

There's another eclectic design though, the McMurty that laps thing faster than petrol cars due to having a fan up the downforce https://youtu.be/5JYp9eGC3Cc I don't think it has a Nurburgring time yet.

My impression was Apple gave up on building EVs because they wouldn't be as profitable as phones and tablets.

Phones weren't that profitable too before the iPhone. They did it anyway.

RIM would disagree. It plenty profitable before the iPhone came out. And Apple already knew building computers was profitable. They cracked how to build a computer the size of a phone.

There aren't any RIM-like companies in the car industry right now. And cars aren't really very useful as computers. Or at least not more useful than phones and tablets and laptops.

BMW has great EVs and they just launched their gen 6 which is probably one of the best on the market. VW also did a stellar job with their newest models. The problem is not that Chinese EVs are entering other markets, BMW and others have done that for decades. The problem is that China is making car manufactoring a commodity. The margins have been high for car manufacturas. China rolls that complelty over with lower…

Part of this is that EVs are significantly simplified compared to ICE; there's less innovation opportunity (motors and batteries), less recurring revenue (service).

U.S. and European dealer, maintenance, even government models are in for a shock when ev percentages approach 50% and even 25% (only continued adoption models away)

Contrasting opinion: BYD made electric busses for US transit agencies. They were the worst buses that I have ever ridden. Today, no U.S. transit agency still uses BYD busses, because none of them managed a service live longer than about a year. BYD vehicles seem really nice for the first few hours, until you start discovering all the corners they cut to make their price point.

Tbh i have to agree with you. I tried byd and cuts corners everywhere. Look at the screen: static video instead of Tesla interactive, low screen dpi. Other small details I can’t recall. I also don’t like Tesla, but at least they have a nicer screen. Tesla also has big gaps between their parts looking from outside.

Corners cut on something I don't want in the car anyway sounds great tbh.

Even if they did they still won't have caught up, because Tesla has had full self driving at the end of every year for the past 8 years.

Their new hope is to have the Optimus humanoid take the driver seat and finally drive the car. Of course, we'll have to wait until this December.

I think the real plan is Optimus will transform into a car to drive you around and occasionally also fight Megatron.

What do you mean by illegal? According to who? Like WTO or something? Genuinely asking, I don't know. I don't see how what they're doing is more illegal than paying corn farmers to make dumbass biofuel. But I don't know international trade law, hence the question.

China's EV subsidies are basically identical to US and EU subsidies. They offer tax credits and other perks to customers, just like in Western countries. Subsidies are not the reason why China's EVs are cheap. The reason is that China has a much more competitive EV market than the US or EU. There are many manufacturers that are competing with one another, the charging infrastructure is much better than in the West, a…

Subsidies are part of the reason. Definitely not the whole reason, but part of it The Chinese provinces pump a bunch of money in to try to make their region's car manufacturers succeed. And every province is doing it. So you have a bunch of carmakers competing for market while being kept alive, so they do the most rational thing possible to gain share: lower prices.

Of course, they're also just good at building things since they do so much of it. And cheaper labor. Much better supply chain.

You can't rely on Chinese companies to make the tanks and rockets you intend aiming at China. Car manufacturers serve many purposes. Aside from keeping the UAW membership onside, they are a strategic buttress for an emerging future war risk. Australia maintained subsidies to Ford and GM for onshore production precisely because of this. And they stopped when a strategic realignment made successive governments decide t…

War with China.. ya'll are nuts. The American zeitgeist is completely poisoned and insane. Listening to this stuff from the outside is kind of horrifying. War with a nuclear armed country ends with a nuclear winter for the whole planet. There is no preparing for war with China unless you want everyone dead (which I'm starting to suspect a lot of people are okay with) This seems so anachronistic.... When was the last…

Maybe not tanks, but certainly drones, no? We need some sort of manufacturing. If not for war itself, as a deterrent? Plus there will still be troops no matter what, so certainly we'll still need to make APCs.

"Car are made using components from all around the world..." That's part of the problem. Building more here may bring some of the components closer, at least to friendlier countries.

3000 hp? Not sure if that's measured at the "crank" or the dynamo, but that's over 2MW, probably pushing 2.5MW of power draw from the batteries assuming a motor efficiency of 90% and some other losses. Apparently that's getting drawn at 1.2kV from the batteries, so "only" around 2kA of current draw. That top power draw would drain the 80kWh batteries in around 2 minutes, though I'm guessing you'd hit thermal throttli…

I guess EVs have the acceleration and top speed crowns now, but it'll take a while for them beat any 24 hours of Le Mans records.

Only from a refueling (and battery heat) perspective though...

The majority of the lemans (or any endurance race) challenge is not from the electric drivetrain (or regenerative braking) but from the ice drivetrain and friction braking. This is reinforced by the ease that WEC and IMSA have had in implementing electric hybrid drivetrains with relative ease over the last 10 years (by most measurements making the endurance more achievable).

Ever since I rode in a BYD in China I've thought it would be great to be able to get one in the USA. It just really felt complete, put together and polished in a way that I haven't seen in a "normie" U.S. car in a long time. Too bad our country uses high tariffs and regulatory barriers to protect its dinosaur companies.

This is the type of statement that often comes from pro China people. Because the quality of BYD in China is lower than outside of China, making it more propaganda than truth. Edit: Sigh. I wish people would actually travel to China and try a BYD and then go to Australia and try BYD. it’s like 2 different cars. The China BYD is trash. BYD in Australia is actually quite nice and feels like really good value.

I would tend you agree with you. I hear about loads of issues with BYD in China, such as battery fires/cars freaking out and locking occupants in or out of the vehicle.

But then I look at the electric BYD buses in London that seemingly have no issues at all (that I've heard of).

We all know about the corrupt tofu dreg projects etc but that seems like more of a domestic problem.
