But will announcing anything 45 days before deliveries begin change that? They might sway a few people who will choose to buy something else in that 45 days, that may have otherwise waited, but that number is ??

they have nothing to gain at this point from announcing anything sooner than the point of ordering. Preorders generate hype and gather data, both are great assets when trying to raise funding. Rivian needs none of the above at this point. You’re right that they have nothing to lose, but they...

How do you know they aren’t? How do you know they haven’t been set in stone for weeks? Months? Why? Do they need to communicate the exact specs to you right now? You haven’t actually purchased one. Just because they haven’t released or announced anything doesn’t mean it’s not happening. It’s...

he’s griping about CarPlay/Android Auto, or the lack thereof. You’ll have Bluetooth audio, but it won’t get much fancier than that, just like Tesla.

✋? that’s me! While a little bigger, I’d be spending at least as much money on an Expedition as I would be on the R1S, and I’d have to gas it up. The R1S is a great value on a premium full-size-ish SUV and checks every box for me.

and a built-in incentive for people to stay and spend money for 20+ minutes! Eat at the Denny’s! Buy a fridge magnet!

I would be very surprised if they made it an exclusive premium vehicle. Utility companies, city governments, and large contractors will all be clamoring for exactly this. It will save them a fortune on gas.

Nah, they wouldn't have sold any cars without the infrastructure they built out, and public infrastructure wouldn't have invested in a project that has no benefit. A classic chicken/egg problem. The availability of supercharging was (and is, though to a lesser extent now) the reason for their...

Just like hard drive and SSD manufacturers include a certain amount of extra capacity to compensate for bad sectors (hard drives) that will crop up eventually, and wear-leveling (SSDs) so they can maintain their rated capacity for a longer period of time.

Yep. The connectors aren't, but they will be software restricted to Rivian owners. I imagine that will change eventually, though.

it would also require running 400V DC through wires that aren’t permanently mounted somewhere… if you didn’t have AC input on the car you’d never be able to use a travel charger-like accessory to obtain any meaningful power levels for charging. Sure, you could permanently install a wall charger...

this is the exact video I’m getting info from. The unit under the rear seat is the on-board charger, which is a rectifier, not an inverter. The front unit is what he calls a High Power Distribution Module, and is essentially a high-voltage fuse box with some logic components, like a smart...

They do! When the charger is a charger, and not an EVSE. On-board chargers are a better idea, at least for now, than installing a DC charger in your house. AC charge points you install at your house aren’t chargers at all, they are fancy light switches that communicate to the car’s on-board...

Tesla “drive units” all have their own integrated inverter as one unit, the other cylindrical drum opposite the actual rotor, stator, and gear reduction. It‘s also the motor controller, it directly connects its 3 phase outputs via bus bar to the motor windings, and modulates those itself to...

yeah. The EU has essentially done that with CCS, and it will probably become the de facto standard in north america because of that. It’s coming. SOON.

You can’t run a rectifier in reverse. There are lots of inverters on the vehicle. One on each motor and probably one on the AC compressor, air compressor, and coolant pump (or one shared between all three). Apparently one more for the outlets too. ?

Charging connectors? There is one vehicle available for purchase in North America that uses CHAdeMO. CCS won. Outside of China and Japan, new EVs are using CCS. Tesla uses CCS with a proprietary connector, you could charge your Rivian at a supercharger with an adapter that put the right pins in...

I work in cybersecurity. Rivian far from the first to make a “software-laden” vehicle like this, and there have been plenty of people “researching” (read: hacking) connected vehicles in the last 15 years. With the exception of Chrysler, no car manufacturer has had a life-threatening software...

I dunno what that would have been. The only moving part in the drive unit is the motor and gear reduction, and a small oil pump driven by the gear reduction. Maybe the coolant pump changing frequencies (speeding up or slowing down), or a fan starting up to start cooling off the coolant it just...
