Using current U.S. numbers [1][2]: average electricity price is $0.162/kWh, might be cheaper off peak or with solar roof; average gas price is $3.083/gal ($0.815/L) for regular, and $3.885/gal ($1.026/L) for premium which is recommended for your Volvo. So, with regular gas: 75L + 50kWh: 75 * 0.815 + 50 * 0.162 = 69.225 75L + 10kWh: 75 * 0.815 + 10 * 0.162 = 63.525 A difference of 10.3%. With premium gas: 75L + 50kWh:…

I'm not in the US. In Europe my Volvo doesn't require premium 98 octane , regular 95 is fine. I appreciate the calculation but I don't know why you're trying so hard to escape the fact that the BYD needs 40kWh more(!!!!!) to travel the same distance(combined with 75 litres of petrol) - it's not hard to see that(as I said 70 comments ago) the BYD is a heavier and less efficient car. There isn't much to argue with here…

Pretty sure your comment trying to paint or at least hint at the BYD being 5x inefficient is the strange one, when it's actually ~1.1x. Which would be really low down on the list of things to consider when purchasing a $150k SUV. If I were in the market for one, I would go for the option that gives me 180km electric range rather than a puny 50km so that all the day to day short range driving is comfortably covered, even if it's only 90% efficient.

In addition, if we compare only the first 180km, your Volvo (using regular gas) comes out at

  75 * 0.815 / (1000 - 50) * (180 - 50) + 10 * 0.162 = 9.98
which is actually more expensive.

Edit: All the precise calculations are in fact quite pointless.

> so the owner is definitely going to notice it on their energy bill.

Highly doubt owners of $150k SUVs are sensitive to ~$600 more over 100k kilometers.

Your logic is still... lacking. I don't say it lightly but it might be the worst case of obtuseness I've seen in many years of HN.

You mix and match units when calculating a ratio of efficiency and it gets you meaningless conclusions. By your "logic" a Tesla M3, a leader in electric efficiency, is the worst of the bunch. It needs ~100kWh of electricity to drive the same 1000km distance. And ICE cars can do that trip with 0 electricity, many even with less fuel so they must be the best?

It makes no sense other than for you to feel good about your car. But your car needs 10-11kWh to drive ideally a pathetic 30km (!) and 75l of fuel for the other 970km. Other ICE cars, or non-PHEV XC60 (the diesel) need no electricity and 50-60l of fuel for the same distance. And they're much cheaper to buy. So why did you pay anywhere between 15k-45k EUR more to have a "compliance car" hybrid that doesn't even float (/s) when this means you're just getting "less efficient"? Unless you bought the bragging rights, and now you're here to defend them.

The goal of any electrified car is to drive as much as possible on electric power alone without the need to run the engine. Not only because ideally some owners can make their own electricity but also for comfort and emissions.

At the end of the article there's an embedded video showing the vehicle doing a tank turn on pavers. The tire manufacturers will love it.

Is tank turn common terminology? I’ve seen skid steer used for this kind of thing on the digger vehicles.

I was parroting the article, but like you I'm more accustomed to skid steer myself.

I'm afraid of the hellscape of even more of these tanks on the road, and even on water now.

Yes, this is not environmentally friendly

What activities with SUVs are environmentally friendly? Keeping to a trail seems ok, everything else like fording rivers, travelling in groups, going off trails invite criticism.

Some scenic parts of China are really far from HSR network, and this car is for people who want to visit those places

Isn't it a car for people who live in big cities, but want to give the impression that they visit such places?

At this price range, I think the people that buy this car no longer need to work and can go wherever they want, or actually need it for work lol

What? If left wheels are in reverse and right wheels in forward then the treads are wearing sideways against the rotation!

there's no direction wear at low speeds. or do you parallel park at 60mph? maybe you drive to work on reverse?

You don't? Learn to drive.

Only 10 to 30 of the 130 mechanics "walked off the job". The press like AP News is straight up lying that 130 mechanics walked off the job, that other media is parroting. The rest like their stock options and performance based pay hikes instead of the union table rates for all: https://sverigesradio.se/artikel/tesla-teknikern-jobbar-trot... https://www.na.se/2023-11-16/tesla-ar-den-basta-arbetsgivare... The number of…

> The number of striking Tesla mechanics is so low that IF Metall refuses to reveal how many are striking, and recently expelled some Tesla employees for not obeying their power play of striking.

Unions here never disclose how many employees are on strike, it's a way to protect the collective action.

> https://sverigesradio.se/artikel/tesla-teknikern-jobbar-trot... > En Tesla-anställd tekniker som Ekot pratat med är kritisk mot fackets kamp för kollektivavtal, och väljer att trots strejken fortsätta arbeta.

> ”Hade jag inte tyckt om mitt jobb, hade det varit så toxiskt som de beskriver, då hade jag bytt jobb”, säger han till Ekot.

That's one technician saying they are happy and disappointed with IF Metall, unless conditions are so egregious to force unanimous action there will always be employees who don't want to participate on a strike. It was the same in the case of Klarna, a lot of employees were not in support of a potential strike but there was enough support to announce it to force Klarna to come into a collective bargaining agreement.

> It's a powerplay by unions who have to resort to sympathy strikes using the government monopoly on giving out registration plates because Tesla workers are happy. Even those are failing as Tesla sales in Sweden have increased over 2022 in Nov and Dec 2023, in spite of blockades on Tesla car imports.

It's become a powerplay, exactly because of how the labour market works here, if a company succeeds in overturning a foundational principle of the labour market then employers have acquired a much more outsized power against employees. IF Metall wants Tesla to abide by what any other car manufacturer abides to in Sweden, in not doing so they are creating a market advantage over other companies who are following the rules of the labour market.

Had Tesla not brought scabs to break the strike nothing of this would be happening, do you understand that? The major issue is that, it's not Tesla not signing a CBA, it's Tesla trying to strong-arm their way through union busting tactics in a society where unions are a core tenet to balance employers-employees relationships. Without unionised power the labour market in Scandinavia/Nordics is not possible to be balanced, the government tries to not interfere.

I do not understand why you defend Tesla so often in Hacker News, I've noticed your username across the years always siding with Tesla, Tesla is in the wrong here and they are paying for it.

If Tesla doesn't like how the market works here they are free to leave at any moment...

Both can do 1k km on 75l, so apart from the Volvo‘s smaller battery, where‘s the difference for the end user? I think it’s a waste of materials to build such cars, but given the weight the consumption seems impressive.

Both cars are plug in hybrids - you need to charge them externally to get the most out of them. BYD needs literally 5x the electricity of the Volvo(50kWh Vs 10kWh) for the same range, so the owner is definitely going to notice it on their energy bill.

The old XC60 can do 50km on 9.1kWh of battery - that’s 18kWh per 100km - IMO that’s super optimistic for an SUV of that size (and assumes no heating, AC, lights etc), but let’s assume it holds.

The BYD can do 180km on a 50kWh battery, that’s 28kWh per 100km.

How did you arrive at 5x worse? It’s not even 2x worse. And again, I don’t buy the 50km claim from Volvo, outside of perfect conditions (eg daytime in May, no rain, no AC, low air resistance).
