There are two styles. You either have alternating rows of square batteries and cooling plates; or in the case of vehicles like BMW’s i-series and the Taycan, simply a giant cooling plate on the top/bottom of the battery stack. You don’t necessarily need to have cooling in between the cells either, particularly for…

If you look at the Model 3 battery pack, wasted space is still a big deal. Not only do the batteries have rows of aluminum heat exchangers in between, but they are also separated by a thermal goop between cells. There’s also the cells themselves- one of the main reasons Tesla moved away from 18650 cells to 21700 ones…

It’s hard to say whether or not the Model 3 “stamped/sandwiched aluminum heat exchanger stack + copious amounts of thermal glue” is the optimum setup. The Porsche Taycan, which already proves its durability, uses rectangular cells, and rather than having heat exchangers in between rows, it simple has a giant plate…

It’s now the 21700 form factor. Packaging, as described above, is an issue in the sense that thermal conditions can be a bit tougher to handle compared to rectangular cells that allow cooling plates to be placed in between. Judging by this article and Model 3 battery teardowns, the answer involves chemical makeup of…

Cylindrical cells is pretty much a Tesla exclusive. if you look at packaging from other OEMs, they’re very often in “pouch” or rectangular form.

I’m not debating whether or not 7 seconds is fun, but the idea that 7 seconds was considered pretty quick is at least 20 years old. It’s an odd statement, like saying “The S2000 didn’t come out very long ago”.

My original statement said, in response to the OP’s remark about 7 seconds being considered fast “not long ago”:

A 1.5L Honda Civic is just under 7 seconds. Maybe there are shittier cars out there to compare to, but at what point does that reflect poorly on a $40K EV?

7 seconds to 60 being considered quick... I don’t think thats been the case since I started getting into cars when I was in highschool.... 20 years ago. Nowadays even econocars are faster

SAE CCS charger is standard in NA and Europe. Tesla themselves joined an organization in Europe that promoted the standardization of the CCS standard.

Toyota is bullish on Hydrogen too, and seeing as the infrastructure for that is currently essentially non-existent in the US, it feels like they’re talking out of both sides of their mouth.

My 8th gen Civic Si has 422,000 KM on it. Original engine, second clutch, new tie rods, new struts, new front strut bearing, new left wheel bearing. That’s it, and the car is driven in Michigan. As long as you keep the rust away, they’ll last for quite a long time. They’re not all that uncommon though, even now, so…

they want to know what these people do to afford to flaunt their wealth so openly. If you watch - most don’t really tell him. Makes you wonder...

The car itself is great, although the rear Bullit logo is pretty cringe.

A “professional engineer” (vs. “engineer”) is also a licensed profession. Most of the US doesn’t seem to care about this distinction, however.

The guy making stuff in the shop is a technician. He might be more competent and have a wider knowledge base than the engineer who is giving him a design to build, but he’s still a tech.

While the battle over the right to use the title of “engineer” vs. “professional engineer” was waged in places like Oregon (https://ij.org/press-release/oregon-engineer-wins-traffic-light-timing-lawsuit/), in this case Musk does not even have an engineering degree or work in an engineering capacity, and should not be…

That’s probably an edge case. Most bus fleets either involve parking in a large depot at night, or at the very least, they have a single pumping station that is shared amongst all busses. In the case of LPG, there’s either a huge tank on site, or a “bobtail” refueling truck that comes by to fill up the busses at the…

That is probably true. But as a stopgap, LPG makes a ton of sense because its emissions are already incredibly low even compared to gasoline (and it doesn’t stink like diesel), the fuel cost is also really low, and maintenance is about the same as any 7.3L gasoline vehicle- which also means that finding a service…

One thing you should probably mention about the LPG busses is that they are low NoX and generally low emissions. Obviously, not sniffing diesel fumes is a huge benefit both for kids and for anyone following these busses, but with increasing fleet emissions requirements it actually makes a ton of sense for schools to…
