Range vs Battery?

How come the Large pack can go 330 miles on a 109kW but the Max needs 140kW pack to go 410 miles?

Added weight of the additional cells?

Large is 135kw

Large is 135kw

For gen 1. It's 109 for gen 2.

Math works out, 330 @ 109 = 3 miles per kWh, 410 @ 140 is 2.9 miles per kWh

I would be amazed if they can do this unless the in house motors are super efficient. My quad with Bosch is closer to 2.3 miles per kWh on long trips unless I really baby it. Highest I recall seeing over a few hundred miles was 2.5 miles per kWh driving under 70 in conserve.

I generally trust the testing, as it should be done to the same standards. Although I’ll be interested in the nuance of there’s a wider distribution of results in extreme scenarios (cold, towing, etc).

I think this will be pretty valuable to both customers and Rivian. A ~20% efficiency boost compared to the original quad means faster charging, and a ~20% reduction in charging costs.

It also helps Rivian. With batteries being commonly quoted at $100/kWh, that’s a ~$2,500 cost decrease from a 135kWh to a 109kWh, with comparable range to the original quad.

I don’t think Ford or GM have anything efficiency related like this in the pipeline. I did the quick math on the Cybertruck, and Tesla’s claims imply around 2.8mi/kWh.
