Update: Rivian got back to us with the following reply regarding the Max Pack battery:
"Instead of adding more cells or modules to an existing battery pack, which would add more mass, our engineers developed a proprietary battery management system that optimizes and increases the usable battery energy from a new version of our 2170 battery cell with advanced chemistry that allows for both higher energy density and higher absolute energy. The total installed capacity for Max Pack is 149kWh."

After several delays, Rivian is finally putting its biggest-ever battery pack – the Max Pack – into production, with the R1T pickup already being delivered to customers, and the R1S SUV expected to follow suit later this fall. And now we learn that this battery actually quite a bit smaller than we expected, even if the resulting range is very impressive.
When it was first announced some time ago, the Max Pack was touted as having a gross capacity of 180 kWh. But the version that''s currently being fitted to customer vehicles has a gross capacity of 149 kWh. By comparison, the next size down, the Large Pack, has 135 kWh, while the Standard Pack offers 105 kWh. (Those are quite large as far as batteries go, but still dwarfed by some giants like the GMC Hummer EV''s 212 kWh battery.)
The Max Pack battery enables an estimated driving range of 400 miles for the R1S equipped with the dual-motor powertrain, making it the longest-range seven-seat electric SUV in the United States, while the R1T can go up to 410 miles with the same power source, according to Rivian.
Furthermore, the range difference between a dual-motor R1S with the Max Pack battery and one with the Large Pack is 48 miles; 400 miles for the Max Pack and 352 miles for the Large Pack.
Those are impressive numbers, but the price increase over the middle-tier Large pack – $10,000 – might make some prospective buyers wonder if the record-setting battery is worth the extra cash, considering it offers just 14 kilowatt-hours more, as Rivian told Car and Driver. We reached out to the California-based EV startup for additional information and will update this article when we hear back.
The next battery – the Large Pack – costs an additional $6,000 and increases the range estimate to 352 miles, while the Max Pack is a $16,000 option over the base model and is only available in conjunction with one of the two dual-motor powertrains – standard or Performance – with the latter adding another $5,000 to the final price, money that brings more power (665 hp) and a quicker 0 to 60 mph time of 3.5 seconds.

The Rivian R1S seven-seat SUV is quickly becoming one of the best-selling all-electric models in the United States with close to 20,000 sold during the first 10 months of the year.
It has one of the broadest choices of versions available, including three battery packs (Standard, Large, and Max) and three powertrain options (Dual, Performance Dual, and Quad), plus a few wheel sizes (20-, 21- and 22-inch). With the recent announcement of the pricing and range for the latest R1S with the Max Pack battery, today we will check out the entire lineup of the 17 available configurations. Aside from the Maxi Pack, the pricing and specs of the other R1S are basically the same as reported in May.
The all-new, 149-kilowatt-hour Max Pack battery (14 kWh bigger than the Large Pack) available on the Rivian R1S with Dual Motor (DM) powertrains makes the R1S the first and only seven-seat electric SUV with 400 miles of EPA Combined range. For reference, the Kia EV9 (7 seats) is rated at up to 280 miles, while the Tesla Model X is up to 348 miles, but both of them are also equipped with much smaller batteries—respectively 99.8-kWh or about 100-kWh (Tesla does not reveal the exact number).
The Rivian R1S DM/Performance DM Max Pack with standard 21-inch wheels has an EPA Combined range of 400 miles, but the switch to bigger 22-inch wheels reduces it by 20 miles or 5% to 380 miles. Meanwhile, the 20-inch wheels with all-terrain (AT) tires return 355 miles (which is 45 miles or over 11% less).
Compared to the Large Pack battery (135 kWh), which is also $10,000 less expensive, the range is noticeably higher:
* EPA-estimated range according to Rivian (not listed by EPA yet); 105 kWh, 135 kWh battery pack capacity according to previous reports, 149 kWh confirmed by Rivian; acceleration depends on the exact configuration; all Rivian R1Ss can tow up to 7,700 lbs
** Expected range of the Standard Pack battery, according to Rivian (no EPA-estimated numbers yet)
*** We assigned all configurations to the 2023 model year, although some might slip into the 2024 model year.
Here is a better look at the EPA-estimated range results (or expected, in the case of the Standard Pack battery) of all 17 versions, plus one additional Quad Motor Large Pack version with 20-inch wheels, which has an EPA rating (289 miles), but is not available:
It would be interesting to see what the range of the originally expected 180-kWh Max Pack would be. Simple math indicates that the range would be 20% higher (compared to 149 kWh), so up to roughly 480 miles and this would be extraordinary. We assume that weight and costs were the biggest concerns that prompted the company to offer the 149 kWh battery instead of a 180 kWh one.
The base Rivian R1S DM Standard Pack, with standard 21-inch wheels, is priced at $78,000 (plus a $1,800 destination charge, the same for all configurations).
The Large Pack option costs $6,000, while the Max Pack option is $16,000 more, which means that the Rivian R1S DM Large Pack starts at $84,000, while the Rivian R1S DM Max Pack starts at $94,000.
The Performance Dual Motor option costs $5,000 more, but it can''t be combined with the Standard Pack battery. The R1S Perf. DM Large Pack starts at $89,000, while Rivian R1S Perf. DM Max Pack starts at $99,000.
Meanwhile, the top-of-the-line Quad Motor powertrain option is $8,000, but in this case, it''s available only with the Large Pack battery and is priced at $92,000.
There is no $7,500 federal tax credit for the Rivian R1S, aside from the entry-level Rivian R1S DM Standard Pack, which fits under the $80,000 price cap, although we don''t whether any will be delivered before the end of 2023.
An electric vehicle''s "usable capacity" is the portion of the battery dedicated to vehicle propulsion and cabin comfort – think driving, heating and air conditioning.
