Pay attention when EPA numbers come out, if they do 2 cycle epa test it has a correction factor that will likely make it accrurate or conservative even, if its 5, may be overrated like Tesla.

So etron is 496 wh/mi at 75 mph so I imagine the real hwy range(at 70/80) of Rivian to be 260 which isn't bad, unless there's a buffer then maybe 240 or so(assuming 10kwh buffer). Which isn't terrible considering maybe when hauling flat it won't be so detrimental to range since the Rivian is...

I just think it's a good standard for a non Tesla. Also not sure you know how much charge you may use 'adventuring' in an EV, but you will possibly want to charge to 100% in those cases. Obviously a lot of this relies on information we simply don't know yet. It's okay for me to be interested and...

Yeah quite familiar with charging practices. But for Rivian I'm wondering if 140 in 20 mins is 400 pack or 300. Also we don't know how accurate 300 is, at like 70mph. Tesla is also bad at that. They get far under EPA at 70mph where Taycan gets far over. Which is another reason I gave Taycan as a...

Yeah again, not sure why you're arguing that. I simply said that I'd rather have 300kw charging and good battery life because it's possible, look at Taycan. It's new but got the buffer for the slight degradation and Porsche feels pretty confident or they wouldn't put it out. (additionally, the...

And yes, I wasn't saying 300kwh was bad for Rivian, I was saying it's necessary. If you somehow went to 0-100 at 300kwh(Which you won't ) still 30 mins to full, which is good I admit, but that isn't happening. 200 is 45, which, still isn't happening. When my Model x would road trip, even at...

Why do you use full capacity for Rivian and not for Taycan? Taycan has a 93.7 kwh battery but electronic buffer(limiting use) to 83, you calculate c rating on full capacity, not some arbitrary safety.

Well that 100% depends if it has a buffer like Taycan or not, and the charging curve. If R1T is 300 miles at using 100% of battery then you're wrong, if its 90% of battery, it's pretty close but again would depend on the curve(at 900v)

Got bored but safe to say it's about 600 (436 marked)

Both IMO, we need to get to a point where charging well is not going to murder your battery, re:taycan.

The battery combine thing is the only thing I could see but again hard to know for sure if it's in LE, I take CS responses with a grain of salt. 300kw at 450v(if what someone said is right) is 666.6 amps, that would be pretty insane.

Wasn’t sure on voltage so just chose a generous one in the 400 range.

Ah good to know, 350 must be cap at 1000v only, still doesn’t mean 300kw at 480v though.

Not that I’m aware. I think EA does 350amp max. Tesla does like 525 very briefly. 300kw at 480 would be 625.

It will be that much faster because it almost has to be 800v, which means 300kw will be at a far lower current than 200kw at 480. Means cooler battery and more sustained rates. It doesn’t make sense though that they’d do 800v shortly after launch so makes us think they’re doing 480v, cause they...

And that's exactly why I said I wish they were less vague. @SANZC02 Now we have a CS saying yes but they excluded that definitive information for a reason. If they knew for sure there is zero reason to exclude that huge highlight.(Because yes, I'm a tough crowd), I'm not buying an suv with 300...

Really wish it was less vague. Is the 300 kw future available in current cars with updates, or future cars only.

My point was that it’s a bit dramatic to think because battery improves, value of old ones will plummet to nothing. Model s early models sell for like 30k still and barely charger faster than a leaf, if that.

If your rivian is zero, imagine what a gas truck would be
