I missed that - most of these things tend to be vaporware, but that certainly seems to be hitting the mark with early reviewers. The more the merrier, bring it on! 650km with 180kwh seems low though - it's only 100km more than a Tesla S 100D despite almost doubling the charge!
Rivian is in SUV or pickup truck versions. Can't really compare the efficiency of a sleek sedan to a monster truck. Like comparing a Range Rover to a coupé.

But we need more different EVs. What I would like to see more of:

1) More types of EVs: Small cars with long range, Station Wagon / Estate, 8-10 person van, utility vehicles

2) Towing capability

3) Battery pack extension modules

4) Active battery temperature control/regulation

5) Charging network - extension on both roadside (highway mainly), and residential, shopping, industrial etc.

-> 1) Station wagons were popular in the USA around the 1970s, a bit before and after that, but today, there are almost none in the US. Highly popular in Northern Europe especially, it's a big segment to miss. One example could be a station car version of the Tesla Model S (not as a remake, but factory version). With towing hook option, please.

Segments in the USA are mini, sedan, van, SUV, pickup and such. Small and simple cars for 4-5 persons, minimum equipment but long range and fast charging.

Mini cars, simple and cheap, but with a long range. Both for longer journeys, but also for those city dwellers who can't (yet) charge at home/work. Fast charging a must, and active battery cooling.

-> 2) Towing capability still confined to a few EVs only. EVs are great for towing, but the reduced range means larger battery packs needed. Possible that towed vehicles could have added battery storage. Even as rental modules, see below.


-> 3) Cassettes/modules with battery packs that can expand the capacity of an EV. On daily basis, the car can weigh much less, be cheaper to buy and free up those saved batteries for producing EVs at a faster rate. When you need longer range, just stop by and rent one or more packs for your journey. The compartments to place the packs in could double as baggage storage when battery extension is not installed. Not only will you get a longer range, but you will also charge up faster: The more batteries you have, the faster you can charge, and charging to less than 100% significantly reduces charging time as well.

-> 4) All EVs should have an active temperature control and monitor system. Otherwise, there will be too many stories of EV batteries range declining too fast. Or even battery failures. Slower charging and all that.

-> 5) When EVs soon become mainstream (also outside of Norway), there needs to be a lot more charging stations. The most important is (relatively) slow chargers scattered in parking lots. Just sockets one can plug into, 3 to 7 kW, depending on how long a typical car parks in that lot. For airport parking, 2kW charging (220V 10A) would be plenty for most visitors. It is important that people can plug in (or even charge automatically with induction charging), and not having to move their cars when charging is done.
