Lucid Gravity vs Rivian R1S

The R1S is a seven-seater in every build. The Gravity is sold as a five- or seven-seat cabin depending on configuration — the third row is optional, so the cheapest Gravity is not automatically a three-row car. The figures on this page describe the seven-seat build.

Second rows differ too: Lucid's configurator offers the Gravity only with a bench, while the R1S pairs a standard bench with optional captain's chairs. A family set on a middle-row aisle has one choice here, and it is the Rivian.

The Gravity publishes 42.6 in of second-row legroom on the Extended Range Battery basis — the largest second-row figure in this dataset, and 5.9 in ahead of the R1S's 36.7. In the third row the Gravity leads on legroom, 33.9 vs 32.8 in, while the R1S leads on headroom, 38.6 vs 37.4 in — the Gravity's headroom figure is published on the Glass Canopy roof basis.

From the safety records we track: Lucid's owner's manual shows the Gravity's curtain airbag running the full length of the roof rail with a callout beside the third row, while the R1S Owner's Guide (dated December 2023) lists roof-rail airbags for the first and second rows only. For child seats, the R1S documents two lower-anchor sets and two top tethers in its third row; the Gravity's manual places lower anchors in the second row only, with tether anchorages on the third-row seat frames.

The Gravity leads at every seat position: 21.3 vs 17.6 cu ft behind the third row, 56.2 vs 48.6 behind the second, and 111.9 vs 90.7 folded — a 21.2 cu ft gap at the maximum. Note the accounting: Lucid's marketing total of roughly 120 cu ft includes the 8.1 cu ft frunk; our 111.9 figure excludes it so the comparison stays apples-to-apples with rivals measured cabin-only.

Even on the conservative basis, the Gravity's hold behind the third row is 3.7 cu ft larger than the R1S's — with seven aboard, that is the difference between a tight airport run and a comfortable one.

The R1S tows 7,700 lb, the Gravity 6,000 — a 1,700 lb margin for the Rivian.

Both ratings cover a small camper or a boat; the R1S keeps the reserve for heavier trailers. If a trailer over 6,000 lb is in the picture, this section decides the comparison on its own.

The Gravity runs from $79,900 (Touring) to $98,900 (Grand Touring, the top configuration shipping today). Lucid also lists a $125,900 GT-S, but it was not yet delivering as of August 2026, so our dataset records the Grand Touring as the ceiling. The R1S runs from $83,990 to $121,990.

At the floor the Gravity undercuts the R1S by $4,090. At the recorded ceilings the order flips hard: the R1S's $121,990 top build is $23,090 above the Grand Touring.

Lucid Gravity: Passengers and cargo are the mission — the largest second-row legroom figure we track (42.6 in), the bigger hold at every configuration, and a lower entry price ($79,900). Accept the bench-only second row, the configuration-optional third row, and a 6,000 lb tow ceiling, and note the model's top GT-S trim was not yet delivering as of August 2026.

Rivian R1S: The mission includes a trailer (7,700 lb), a preference for captain's chairs, tallest-passenger third-row headroom of the pair (38.6 in), or documented third-row child-seat anchors. Every build is a seven-seater, and the budget can run to $121,990 if the configurator gets away from you.
